Also begin to start work on cross compilation, though that will have to
be finished later.
The patches are based on the first version of
https://reviews.llvm.org/D99484. It's very annoying to do the
back-porting but the review has uncovered nothing super major so I'm
fine sticking with what I've got.
Beyond making the outputs work, I also strove to re-sync the packages,
as they have been drifting pointlessly apart for some time.
----
Other misc notes, highly incomplete
- lvm-config-native and llvm-config are put in `dev` because they are
tools just for build time.
- Clang no longer has an lld dep. That was introduced in
db29857eb3, but if clang needs help
finding lld when it is used we should just pass it flags / put in the
resource dir. Providing it at build time increases critical path
length for no good reason.
----
A note on `nativeCC`:
`stdenv` takes tools from the previous stage, so:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.stdenv.cc`: `(?0, ?1, x)`
while:
1. `pkgsBuildBuild`: `(?1, x, x)`
2. `pkgsBuildBuild.targetPackages`: `(x, x, ?2)`
3. `pkgsBuildBuild.targetPackages.stdenv.cc`: `(?1, x, x)`
Unfortunately this requires a bit of trickery with pkg-config to get to
work. The root issue is that the mirage-xen assumes that we use the
default libdir of dune ($out/lib) whereas we install to an OCaml
version-specific site-lib directory. Thus the manually created
pkg-config file makes wrong assumptions (which warrants a patch) and the
.pc file is installed to the wrong location (which is fixed with a mv
invocation).
I should have changed meta.branch in 70e33e3ae3 ("glsurf: use current giflib"),
but I overlooked it.
The bitbucket URL doesn't seem to exist any more, so I've updated the
homepage to the GitLab repository we fetch the sources from.
Fixes: 70e33e3ae3 ("glsurf: use current giflib")
Unfortunately there's no way to get Haxe 4.0 and 4.1 to work with extlib
1.7.8 (not even without the minimal install), so we need to package
1.7.7 again, at least until 1.7.9 (?) brings backwards compatibility
packages, hopefully.
This requires bumping the version of camlimages used by glsurf to a
version that supports current giflib. The most recent versions of
camlimages (even of 4.x) don't support ocaml 4.01 any more, so I've
upgraded to 4.1.2 here, the last version that supports ocaml 4.01 (and
which happily supports current giflib).
