Docker images used to be, essentially, a linked list of layers. Each
layer would have a tarball and a json document pointing to its parent,
and the image pointed to the top layer:
imageA ----> layerA
|
v
layerB
|
v
layerC
The current image spec changed this format to where the Image defined
the order and set of layers:
imageA ---> layerA
|--> layerB
`--> layerC
For backwards compatibility, docker produces images which follow both
specs: layers point to parents, and images also point to the entire
list:
imageA ---> layerA
| |
| v
|--> layerB
| |
| v
`--> layerC
This is nice for tooling which supported the older version and never
updated to support the newer format.
Our `buildImage` code only supported the old version, so in order for
`buildImage` to properly generate an image based on another image
with `fromImage`, the parent image's layers must fully support the old
mechanism.
This is not a problem in general, but is a problem with
`buildLayeredImage`.
`buildLayeredImage` creates images with newer image spec, because
individual store paths don't have a guaranteed parent layer. Including
a specific parent ID in the layer's json makes the output less likely
to cache hit when published or pulled.
This means until now, `buildLayeredImage` could not be the input to
`buildImage`.
The changes in this PR change `buildImage` to only use the layer's
manifest when locating parent IDs. This does break buildImage on
extremely old Docker images, though I do wonder how many of these
exist.
This work has been sponsored by Target.
This ensures that RPATH entries like "/foo/build/bar" doesn't trigger a
match when TMPDIR is "/build/bar". (I've had this problem with a
prebuilt package.)
If there was no older file than $NIX_BUILD_TOP this would result in a
warning, e.g. with nix-info.

This commit causes melpaBuild to use package-build from melpa/package-build
instead of melpa/melpa. Development of package-build happens in the former
repository whereas the latter is much larger, containing also the MELPA
recipes. We do not need to fetch the MELPA recipes from melpa/melpa, as we fetch
them one-by-one for Nixpkgs.
No real function change here, but this updates the trivial and melpa builders to
be formatted more consistently with the rest of the builders, and swaps
`eval "$preBuild"` for the more standard `runHook preBuild`.
If the file in question is not a shared object file but an ELF, we
really want to skip the file, because we won't have anything to patch
there.
For example if the file is created via "gcc -c -o foo.o foo.c", we don't
get a segment header and so far autoPatchelf was trying to patch such a
file.
By checking for missing segment headers, we're now no longer going to
attempt patching such a file.

This function is useful if autoPatchelf is invoked during some of the
phases of a build and allows to add arbitrary shared objects to the
search path.
So far the same functionality was in autoPatchelf itself, but not
available as a separate function, so when adding shared objects to the
dependency cache one would have to do so manually.
The function also has the --no-recurse flag, which prevents recursing
into subdirectories.

This is to be used with the autoPatchelf command and allows to only
patch a specific file or directory without recursing into
subdirectories.
Apart from being able to run the command in a standalone way, as
detailled in the previous commit this is also needed for the Android SDK
emulator, because according to @svanderburg there are subdirectories we
don't want to patch.
The reason why I didn't use GNU getopt is that it might not be available
on all operating systems and the getopts bash builtin doesn't support
long arguments. Apart from that, the implementation for recognizing the
flag is pretty trivial and it's also using bash builtins only, so if we
want to do something really fancy someday, we can still change it.

If you want to only run autoPatchelf on a specific path and leave
everything else alone, we now have a $dontAutoPatchelf environment
variable, which causes the postFixup hook to not run at all.
The name "dontAutoPatchelf" probably is a bit weird in conjunction with
putting "autoPatchelfHook" in nativeBuildInputs, but unless someone
comes up with a better name I keep it that way because it's consistent
with all the other dontStrip, dontPatchShebangs, dontPatchELF and
whatnot.
A specific example where this is needed is when building the Android SDK
emulator, which contains a few ARM binaries in subdirectories that
should not be patched. If we were to run autoPatchelf on all outputs
unconditionally we'd run into errors because some ARM libraries couldn't
be found.
Signed-off-by: aszlig <aszlig@nix.build>
The autoPatchelf main function which is run against all of the outputs
was pretty much tailored towards this specific setup-hook and was
relying on $prefix to be set globally.
So if you wanted to run autoPatchelf manually - let's say during
buildPhase - you would have needed to run it like this:
prefix=/some/directory autoPatchelf
This is now more intuitive and all you need to do is run the following:
autoPatchelf /some/directory

On Linux the `$TMPDIR` is `/build`. The TMPDIR audit looks for `$TMPDIR`
in the build output, which will then fail with packages like
/buildkite-agent.
This fixes the heuristic to look for `$TMPDIR/` instead.
Completely breaks darwin. Every package in the stdenv that has shebangs

This allows to simplify the usage of libredirect inside of nix build
sandboxes. Add "libredirect.hook" to the build inputs to get everything
linked in automaticall. All that's left is to set NIX_REDIRECTS and call
the target program.
Since Nix 2 is now the stable Nix version, we can use closureInfo
which simplifies the Nix database initialisation (size and hash are
included in the "dump").
Pull request #50246 was merged a bit too quickly and it was supposed to
fix libredirect on Darwin. However it still failed on Darwin and this
was missed by the person merging the pull request.
The reason this was failing was that there is no __xstat* on Darwin.
So I'm adding a wrapper for stat() as well as it works on Darwin and it
still doesn't hurt on GNU/Linux.

This is just a sanity check on whether the library correctly wraps the
syscalls and it's using the "true" executable for posix_spawn() and
execv().
The installCheckPhase is not executed if we are cross-compiling, so this
shouldn't break cross-compilation.
One thing I'm not actually sure is whether ${coreutils}/bin/true is
universally available on all the platforms, nor whether all the
functions we use in the test are available, but we can still fix that
after we've found out about that.

This adds the shell shebang to the wrapper script. Without this,
emacs and in particular agda2-mode (but probably other applications as
well) return a format error when trying to execute agda.
With the previous commit `propagateDoc` is now always given the correct value
(i.e. it is never set to `true` when there are no `man` and `info` outputs).
Hence, we can simply symlink the original outputs to the wrapper outputs.
Pros:
- simpler, less indirection compared to `propagated-user-env-packages`,
- uses less inodes (1 symlink, which nix then simply automatically resolves
and removes, vs. two directories and a file),
- makes direct references like "export MANPATH=${stdenv.cc.man}/share/man"
simply work.
Cons:
- I'm not aware of any.
This and the previous commit together almost completely revert commits

I originally thought it would just be enough to just check for an INTERP
section in isExecutable, however this would mean that we don't detect
statically linked ELF files, which would break our recent improvement to
gracefully handle those.
In theory, we are only interested in ELF files that have an INTERP
section, so checking for INTERP would be enough. Unfortunately the
isExecutable function is already used outside of autoPatchelfHook, so we
can't easily get rid of it now, so let's actually strive for more
correctness and make isExecutable actually match ELF files that are
executable.
So what we're doing instead now is to check whether either the ELF type
is EXEC *or* we have an INTERP section and if one of them is true we
should have an ELF executable, even if it's statically linked.
Along the way I also set LANG=C for the invocations of readelf, just to
be sure we don't get locale-dependent output.
Tested this with the following command (which contains almost[1] all the
packages using autoPatchelfHook), checking whether we run into any
library-related errors:
nix-build -E 'with import ./. { config.allowUnfree = true; };
runCommand "test-executables" {
drvs = [
anydesk cups-kyodialog3 elasticsearch franz gurobi
masterpdfeditor oracle-instantclient powershell reaper
sourcetrail teamviewer unixODBCDrivers.msodbcsql17 virtlyst
vk-messenger wavebox zoom-us
];
} ("for i in $drvs; do for b in $i/bin/*; do " +
"[ -x \"$b\" ] && timeout 10 \"$b\" || :; done; done")
'
Apart from testing against library-related errors I also compared the
resulting store paths against the ones prior to this commit. Only
anydesk and virtlyst had the same as they didn't have self-references,
everything else differed only because of self-references, except
elasticsearch, which had the following PIE binaries:
* modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/autoconfig
* modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/autodetect
* modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/categorize
* modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/controller
* modules/x-pack/x-pack-ml/platform/linux-x86_64/bin/normalize
These binaries were now patched, which is what this commit is all about.

In strictDeps=false, autoPatchshebangs should use
--build (corresponding to PATH) to lookup commands. This restores the
previous behavior of patchshebangs so that we don’t break stuff that
isn’t careful in the buildInputs vs. nativeBuildInputs distinction.
Unfortunately this won’t work under cross compilation.
- respect libc’s incdir and libdir
- make non-unix systems single threaded
- set LIMITS_H_TEST to false for avr
- misc updates to support new libc’s
- use multilib with avr
For threads we want to use:
- posix on unix systems
- win32 on windows
- single on everything else
For avr:
- add library directories for avrlibc
- to disable relro and bind
- avr5 should have precedence over avr3 - otherwise gcc uses the wrong one
Usuage: Add breakpointHook to your `buildInputs` like this:
stdenv.mkDerivation rec {
# ...
buildInputs = [ breakpointHook ];
});
When the build fails as show in this example:
pkgs.hello.overrideAttrs (old: {
buildInputs = [ breakpointHook ];
postPatch = ''
false
'';
});
It will halt execution printing the following message:
build failed in patchPhase with exit code 1
To attach to this build run the following command as root:
cntr attach -t command cntr-/nix/store/ynyb4n82x2r7sldd58pbb405jdqh5f00-hello-2.10
Installing cntr and running the command will provide shell access to the
build sandbox of failed build:

Create a many-layered Docker Image.
Implements much less than buildImage:
- Doesn't support specific uids/gids
- Doesn't support runninng commands after building
- Doesn't require qemu
- Doesn't create mutable copies of the files in the path
- Doesn't support parent images
If you want those feature, I recommend using buildLayeredImage as an
input to buildImage.
Notably, it does support:
- Caching low level, common paths based on a graph traversial
algorithm, see referencesByPopularity in
0a80233487993256e811f566b1c80a40394c03d6
- Configurable number of layers. If you're not using AUFS or not
extending the image, you can specify a larger number of layers at
build time:
pkgs.dockerTools.buildLayeredImage {
name = "hello";
maxLayers = 128;
config.Cmd = [ "${pkgs.gitFull}/bin/git" ];
};
- Parallelized creation of the layers, improving build speed.
- The contents of the image includes the closure of the configuration,
so you don't have to specify paths in contents and config.
With buildImage, paths referred to by the config were not included
automatically in the image. Thus, if you wanted to call Git, you
had to specify it twice:
pkgs.dockerTools.buildImage {
name = "hello";
contents = [ pkgs.gitFull ];
config.Cmd = [ "${pkgs.gitFull}/bin/git" ];
};
buildLayeredImage on the other hand includes the runtime closure of
the config when calculating the contents of the image:
pkgs.dockerTools.buildImage {
name = "hello";
config.Cmd = [ "${pkgs.gitFull}/bin/git" ];
};
Minor Problems
- If any of the store paths change, every layer will be rebuilt in
the nix-build. However, beacuse the layers are bit-for-bit
reproducable, when these images are loaded in to Docker they will
match existing layers and not be imported or uploaded twice.
Common Questions
- Aren't Docker layers ordered?
No. People who have used a Dockerfile before assume Docker's
Layers are inherently ordered. However, this is not true -- Docker
layers are content-addressable and are not explicitly layered until
they are composed in to an Image.
- What happens if I have more than maxLayers of store paths?
The first (maxLayers-2) most "popular" paths will have their own
individual layers, then layer #(maxLayers-1) will contain all the
remaining "unpopular" paths, and finally layer #(maxLayers) will
contain the Image configuration.
Using a simple algorithm, convert the references to a path in to a
sorted list of dependent paths based on how often they're referenced
and how deep in the tree they live. Equally-"popular" paths are then
sorted by name.
The existing writeReferencesToFile prints the paths in a simple
ascii-based sorting of the paths.
Sorting the paths by graph improves the chances that the difference
between two builds appear near the end of the list, instead of near
the beginning. This makes a difference for Nix builds which export a
closure for another program to consume, if that program implements its
own level of binary diffing.
For an example, Docker Images. If each store path is a separate layer
then Docker Images can be very efficiently transfered between systems,
and we get very good cache reuse between images built with the same
version of Nixpkgs. However, since Docker only reliably supports a
small number of layers (42) it is important to pick the individual
layers carefully. By storing very popular store paths in the first 40
layers, we improve the chances that the next Docker image will share
many of those layers.*
Given the dependency tree:
A - B - C - D -\
\ \ \ \
\ \ \ \
\ \ - E ---- F
\- G
Nodes which have multiple references are duplicated:
A - B - C - D - F
\ \ \
\ \ \- E - F
\ \
\ \- E - F
\
\- G
Each leaf node is now replaced by a counter defaulted to 1:
A - B - C - D - (F:1)
\ \ \
\ \ \- E - (F:1)
\ \
\ \- E - (F:1)
\
\- (G:1)
Then each leaf counter is merged with its parent node, replacing the
parent node with a counter of 1, and each existing counter being
incremented by 1. That is to say `- D - (F:1)` becomes `- (D:1, F:2)`:
A - B - C - (D:1, F:2)
\ \ \
\ \ \- (E:1, F:2)
\ \
\ \- (E:1, F:2)
\
\- (G:1)
Then each leaf counter is merged with its parent node again, merging
any counters, then incrementing each:
A - B - (C:1, D:2, E:2, F:5)
\ \
\ \- (E:1, F:2)
\
\- (G:1)
And again:
A - (B:1, C:2, D:3, E:4, F:8)
\
\- (G:1)
And again:
(A:1, B:2, C:3, D:4, E:5, F:9, G:2)
and then paths have the following "popularity":
A 1
B 2
C 3
D 4
E 5
F 9
G 2
and the popularity contest would result in the paths being printed as:
F
E
D
C
B
G
A

This causes problems for packages built using a bootstrap stdenv,
resulting in references to /bin/sh or even bootstrap-tools. The darwin

With these changes there is only one derivation which has altered
contents, which is "franz". However the reason why it has differing
contents is not directly because of the autoPatchelfHook changes, but
because the "env-vars" file from the builder is in
"$out/opt/franz/env-vars" (Cc: @gnidorah) and we now have different
contents for NIX_CFLAGS_COMPILE and other environment variables.
I also tested this against a random static binary and the hook no longer
tries to patch it.

The "maxx" package recursively runs isExecutable on a bunch of files and
since the change to use "readelf" instead of "file" a lot of errors like
this one are printed during build:
readelf: Error: Not an ELF file - it has the wrong magic bytes at the
start
While the isExecutable was never meant to be used outside of the
autoPatchelfHook, it's still a good idea to silence the errors because
whenever readelf fails, it clearly indicates that the file in question
is not a valid ELF file.

If the ELF file is not an executable, we do not get a PT_INTERP section,
because after all, it's a *shared* library.
So instead of checking for PT_INTERP (to avoid statically linked
executables) for all ELF files, we add another check to see if it's an
executable and *only* skip it when it is and there's no PT_INTERP.

The `overrideScope` bound by `makeScope` (via special `callPackage`)
took an override in the form `super: self { … }`. But this is
dangerously close to the `self: super { … }` form used by *everything*
else, even other definitions of `overrideScope`! Since that
implementation did not even share any code either until I changed it
recently in 3cf43547f4, this inconsistency
is almost certainly an oversight and not intentional.
Unfortunately, just as the inconstency is hard to debug if one just
assumes the conventional order, any sudden fix would break existing
overrides in the same hard-to-debug way. So instead of changing the
definition a new `overrideScope'` with the conventional order is added,
and old `overrideScope` deprecated with a warning saying to use
`overrideScope'` instead. That will hopefully get people to stop using
`overrideScope`, freeing our hand to change or remove it in the future.
02c09e0171 (NixOS/nixpkgs#44558) was reverted in
c981787db9 but, as it turns out, it fixed an issue
I didn't know about at the time: the values of `propagateDoc` options were
(and now again are) inconsistent with the underlying things those wrappers wrap
(see NixOS/nixpkgs#46119), which was (and now is) likely to produce more instances
of NixOS/nixpkgs#43547, if not now, then eventually as stdenv changes.
This patch (which is a simplified version of the original reverted patch) is the
simplest solution to this whole thing: it forces wrappers to directly inspect the
outputs of the things they are wrapping instead of making stdenv guess the correct
values.
Because dates are an impurity, by default buildImage will use a static
date of one second past the UNIX Epoch. This can be a bit frustrating
when listing docker images in the CLI:
$ docker image list
REPOSITORY TAG IMAGE ID CREATED SIZE
hello latest 08c791c7846e 48 years ago 25.2MB
If you want to trade the purity for a better user experience, you can
set created to now.
pkgs.dockerTools.buildImage {
name = "hello";
tag = "latest";
created = "now";
contents = pkgs.hello;
config.Cmd = [ "/bin/hello" ];
}
and now the Docker CLI will display a reasonable date and sort the
images as expected:
$ docker image list

This commit adds test based on real-world crates (brotli).
There were a few more edge cases that were missing beforehand. Also it
turned out that we can get rid of the `finalBins` list since that will
now be handled during runtime.
The build expression got quiet large over time and to make it a bit
easier to grasp the different scripts involved in the build are now
separated from the nix file.
Cargo has a few odd (old) ways of picking source files if the `bin.path`
attribute isn't given in the Cargo.toml. This commit adds support for
some of those. The previous behaviour always defaulted to `src/main.rs`
which was not always the right choice.
Since there is look-ahead into the unpacked sources before running the
actual builder the path selection logic has to be embedded within the
build script.
`buildRustCrate` currently supports two ways of running building
binaries when processing a crate:
- Explicit definition of all the binaries (& optionally the paths to
their respective `main.rs`) and,
- if not binary was explictly configured all files matching the patterns
`src/main.rs`, `src/bin/*.rs`.
When the explicit list is given without path information paths are now
being picked from a list of candidates. The first match wins. The order
is the same as within the cargo compatibility code.
If the crate does not provide any libraries the path `src/{bin_name}.rs`
is also considered.
All underscores within the binary names are translated into dashes (`-`)
before the lookups are made. This seems to be a common convention.
Previously the Release.xz URL would show up with a new hash whenever
debian releases an update. By using archive.org we should have a stable
source for those. I wasn't able to find the equivalent in the debian
world. Maybe they don't keep all the different Release files around..
By setting useRealVendorConfig explicitly to true, the actual (slightly
modified) config generated by cargo-vendor is used.
This solves a problem, where the static vendor config in
pkgs/build-support/rust/default.nix would not sufficiently replace all
crates Cargo is looking for.
As useRealVendorConfig (and writeVendorConfig in fetchcargo) default to
false, there should be no breakage in existing cargoSha256 hashes.
Nethertheless, imho using this new feature should become standard. A
possible deprecation path could be:
- introduce this patch
- set useRealVendorConfig explicitly to false whereever cargoSha256 is
set but migration is not wanted yet.
- after some time, let writeVendorConfig default to true
- when useRealVendorConfig is true everywhere cargoSha256 is set and
enough time is passed, `assert cargoVendorDir == null ->
useRealVendorConfig;`, remove old behaviour
- after some time, remove all appearences of useRealVendorConfig and the
parameter itself
Introduce a `skawarePackages.buildPackage` function that contains the
common setup, removing a lot of duplication.
In particular, we require that the build directory has to be empty
after the `fixupPhase`, to make sure every relevant file is moved to
the outputs.
A next step would be to deduplicate the `configureFlags` attributes
and only require a `skawareInputs` field.
There's no reason `linkFarm` can't be used for symlinks in
subdirectories, except that currently it doesn't ensure the directory
of the link exists. This backwards-compatible change expands the utility
of the function.
This hopefully makes patchShebangs respect cross compilation. It
introduces the concept of the HOST_PATH. Nothing is ever executed on
it but instead used as a way to get the proper path using ‘command
-v’. Needs more testing.

search for tests in that folder, but also create a .pytest-cache folder.
Not only is this state we don't want, but it was also causing

* Revert "meson: 0.46.1 -> 0.47.0"
With meson 0.47.0 (or 0.47.1, or git)
things are very wrong re:rpath handling
resulting in at best missing libs but
even corrupt binaries :(.
When we run patchelf it masks the problem
by removing obviously busted paths.
Which is probably why this wasn't noticed immediately.
Unfortunately the binary already
has a long series of paths scribbled
in a space intended for a much smaller string;
in my testing it was something like
lengths were 67 with 300+ written to it.
I think we've reported the relevant issues upstream,
but unfortunately it appears our patches
are what introduces the overwrite/corruption
(by no longer being correct in what they assume)
This doesn't look so bad to fix but it's
not something I can spend more time on
at the moment.
--
Interestingly the overwritten string data
(because it is scribbled past the bounds)
remains in the binary and is why we're suddenly
seeing unexpected references in various builds
-- notably this is is the reason we're
seeing the "extra-utils" breakage
that entirely crippled NixOS on master
(and probably on staging before?).
Fixes#43650.
This reverts commit 305ac4dade.

package-build expects the recipe file name to match the Emacs package
name. `melpaBuild` takes an extra argument `ename` for the Emacs package
name (default: `pname`, the Nix package name) which is used to name the recipe
file.
Fixes: #43893

This makes the command ‘nix-env -qa -f. --arg config '{skipAliases =
true;}'’ work in Nixpkgs.
Misc...
- qtikz: use libsForQt5.callPackage
This ensures we get the right poppler.
- rewrites:
docbook5_xsl -> docbook_xsl_ns
docbook_xml_xslt -> docbook_xsl
diffpdf: fixup
With the recent update of BusyBox to version 1.29.0 in
d6aa506e3b there is now a new dependency
on libresolv.
This now throws a runtime error when executing ash, eg. whenever we do
something like this:
nix-build -E 'with import ./. {}; vmTools.runInLinuxVM hello'
The resulting error will be:
.../ash: error while loading shared libraries: libresolv.so.2: cannot
open shared object file: No such file or directory
I tried to override BusyBox with enableStatic, but that still requires
parts of glibc:
Static linking against glibc, can't use --gc-sections
Trying libraries: crypt m resolv
Library crypt is not needed, excluding it
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Library m is needed, can't exclude it (yet)
Library resolv is needed, can't exclude it (yet)
Final link with: m resolv
In the long term maybe switching to a more minimal C library such as
musl would make more sense, but for now I just added libresolv.so to the
initrd which fixes the runtime error.

All package sets are simultaneously updated to accommodate changes to
package-build. Due to new restrictions in package-build, all packages using
`melpaBuild` must now provide a recipe file, even those packages which are not
included in upstream MELPA.
So far the runtimeDependencies variable has been rather useless unless
you also set dontPatchelf, because the patchelf setup hook ran *after*
the autoPatchelfHook and thus stripped off the additional RPATHs added
using runtimeDependencies.
I did this by moving the autoPatchelfHook to be run in postFixup instead
of fixupOutput, however I needed to replicate the for loop that runs the
hook on all outputs.
Until we have a way to influence order of execution for hooks I've
marked this with an XXX so that we can use fixupOutput again.
Tested this against all packages that use autoPatchelfHook using the
following and checking whether the output contains any errors concerning
shared libraries:
nix-build -E 'with import ./. { config.allowUnfree = true; };
runCommand "test-executables" {
drvs = [
masterpdfeditor franz zoom-us anydesk teamviewer maxx
oracle-instantclient cups-kyodialog3 virtlyst powershell
];
} "for i in $drvs; do for b in $i/bin/*; do \"$b\" || :; done; done"
'

Since this is probably never the desired case and has led to actual
issues, see the comments at:

This might also happen when pulling a patch from GitHub or a similar web
interface without explicitly selecting the "raw" format.
Excludes and includes are implemented by passing the parameters to the
respective flags of `filterdiff`. Those were passed unescaped until now.
Since those flags expect patterns (similar to shell globs), something
like `/some/path/*` might be used to exclude or include all files in
some path. Without escaping the shell would expand the `*`, leading to
unexpected behaviour.
This commit was originally introduced as part of #41420 and then
reverted with the rest of that PR. However there was no reason to revert
his particular commit.
docker-tools tests load images without specifying any tag
value. Docker then uses the image with tag "latest" which doesn't
exist anymore since commit 39e678e24e.
In particular, this contains Firefox-related and libgcrypt updates.
Other larger rebuilds would apparently need lots of time to catch up
on Hydra, due to nontrivial rebuilds in other branches than staging.
A .la file specifies linker flags to link with the library it describes. Its
"dependency_libs" field lists the libraries that this library depends upon.
This list often contains "-l" flags without corresponding "-L" flags. Many
packages in Nixpkgs deal with this in one of these ways:
- delete .la file [1]
- clear dependency_libs [2]
- add -L flags to dependency_libs [3]
- propagate dependencies [4]
Sometimes "dependency_libs" contain wrong "-L" flags pointing to the "dev"
output with headers rather than to the main output with libraries. They have to
be edited or deleted to reduce closure size [5].
Deleting .la files is often but not always safe [6]. Atomatically deleting as
many of them as possible is complex [7]. Deleting .la files that describe
shared rather than static libraries is probably safe; but clearing their
"dependency_libs" field achieves the same effect with less potential for
unintended consequences. This is the approach that may be enabled for all
Nixpkgs.
