Apply OS checks to host platform, not build Previously, the build system used uname(1) output when it wanted to check the operating system it was being built for, which meant that it didn't take into-account cross-compilation when the build and host operating systems were different. To fix this, instead of consulting uname output, we consult the host triple, specifically the third "kernel" part. For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a simple ifeq to test whether we're compiling for that system, but for other platforms, like Darwin, FreeBSD, or Solaris, we have to use a more complicated check to take into account the version numbers at the end of the "kernel"s. I couldn't find a way to just strip these version numbers in GNU Make without shelling out, which would be even more ugly IMO. Because these checks differ between kernels, and the patsubst ones are quite fiddly, I've added variables for each host OS we might want to check to make them easier to reuse. 2021-06-01 07:58:21 +00:00			`HOST_OS = @host_os@`

enable LTO in optimized builds gives 2-5% performance improvement across a board of tests. LTO is broken when using clang; some libs link fine while others crash the linker with a segfault in the llvm linker plugin. 🙁 2021-12-21 18:34:40 +00:00			`CXXLTO = @CXXLTO@`

Add x86_64 compute levels as additional system types When performing distributed builds of machine learning packages, it would be nice if builders without the required SIMD instructions can be excluded as build nodes. Since x86_64 has accumulated a large number of different instruction set extensions, listing all possible extensions would be unwieldy. AMD, Intel, Red Hat, and SUSE have recently defined four different microarchitecture levels that are now part of the x86-64 psABI supplement and will be used in glibc 2.33: https://gitlab.com/x86-psABIs/x86-64-ABI https://lwn.net/Articles/844831/ This change uses libcpuid to detect CPU features and then uses them to add the supported x86_64 levels to the additional system types. For example on a Ryzen 3700X: $ ~/aps/bin/nix -vv --version \| grep "Additional system" Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux 2021-02-16 13:32:12 +00:00			`HAVE_LIBCPUID = @HAVE_LIBCPUID@`

Use pkg-config-provided LDFLAGS for libsqlite3 and libcurl. Previously, pkg-config was already queried for libsqlite3's and libcurl's link flags. However they were not used, but hardcoded instead.

fix make's impurity on /bin/sh This is important when using tooling like BEAR to generate compilation database since the used glibc version needs to match for LD_PRELOAD to work. It might be also beneficial when building on systems other than NixOS with nix develop since /bin/sh might be not bash (which is what all nix devs use for testing). This fix is not perfect because Makefile.config.in itself is also build with make but strictly better than the status quo. 2020-07-18 06:58:37 +00:00			`SHELL = @bash@`
Use libsodium instead of OpenSSL for binary cache signing Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA signatures. Public keys are also much shorter, so they're now specified directly in the nix.conf option ‘binary-cache-public-keys’. The new command ‘nix-store --generate-binary-cache-key’ generates and prints a public and secret key. 2015-02-04 15:43:32 +00:00			`SODIUM_LIBS = @SODIUM_LIBS@`
