Issue description

This is possibly an instance of this issue: #53424
With glibc dontStrip = true commented out as described in #35251, The dependencies of a simple C program, when cross compiled, are fairly minimal (Throughout this issue report, host architecture is aarch64, so armv7l target is cross compiled):

% nix-store -q --tree $(nix eval nixpkgs.pkgsCross.armv7l-hf-multiplatform.hello.outPath | tr -d '"') 
/nix/store/76inxagd7vkgz947nc5arf7vghsad03a-hello-2.10-armv7l-unknown-linux-gnueabihf

However, if you cross compile a very simple C++ application (I created a trivial C++ hello world package, hello-cpp), it has a massive closure:

% nix-store -q --tree $(nix eval nixpkgs.pkgsCross.armv7l-hf-multiplatform.hello-cpp.outPath | tr -d '"')

We can see that the actual dependencies of the hello-cpp binary are quite reasonable: It needs the linker, libc, libm from the cross-glibc package, but also needs libstdc++ and libgcc_s.

% /nix/store/8yanx7clq5050zf3ikyjrbivshzhvhp1-glibc-2.27-armv7l-unknown-linux-gnueabihf/lib/ld-linux-armhf.so.3 --list /nix/store/m20s5wffs450mgw8q135976anlxhcwc3-hello-cpp-2-armv7l-unknown-linux-gnueabihf/bin/hello-cpp 
        libstdc++.so.6 => /nix/store/8kv91ppvnwj8hi0l6d4ra4gjc5x03h9b-armv7l-unknown-linux-gnueabihf-stage-final-gcc-7.4.0/armv7l-unknown-linux-gnueabihf/lib/libstdc++.so.6 (0xf6fa2000)
        libm.so.6 => /nix/store/8yanx7clq5050zf3ikyjrbivshzhvhp1-glibc-2.27-armv7l-unknown-linux-gnueabihf/lib/libm.so.6 (0xf6f1c000)
        libgcc_s.so.1 => /nix/store/8kv91ppvnwj8hi0l6d4ra4gjc5x03h9b-armv7l-unknown-linux-gnueabihf-stage-final-gcc-7.4.0/armv7l-unknown-linux-gnueabihf/lib/libgcc_s.so.1 (0xf6eed000)
        libc.so.6 => /nix/store/8yanx7clq5050zf3ikyjrbivshzhvhp1-glibc-2.27-armv7l-unknown-linux-gnueabihf/lib/libc.so.6 (0xf6dac000)

However, it appears, libstdc++ and libgcc are bundled up with lots of other libs and binaries in the *-armv7l-unknown-linux-gnueabihf-stage-final-gcc-7.4.0 output. Since these binaries include the cross compiler, they depend on various host packages such as glibc.

I notice that if I compile hello-cpp for the native platform, it instead depends on gcc-7.4.0-libs, which includes only the libraries. Is there a reason the cross-toolchain C++ libraries aren't split into their own output?

I didn't manage to find it at the time, but it looks like this is probably the same issue as #58501. I'll test the PR linked to that one...

Looks like sotruss is possibly the weak link. It's a bash script, so it depends on bash, but as part of glibc-2.27-armv7l-unknown-linux-gnueabihf-dev, it should probably depend on something like bash-4.4-p23-armv7l-unknown-linux-gnueabihf instead of the host bash.

However, hello-cpp is just a binary, so it shouldn't really need the -dev package in the first place.

Thank you for your contributions.

This has been automatically marked as stale because it has had no activity for 180 days.

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

  1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
  2. Ask on the NixOS Discourse.
  3. Ask on the #nixos channel on irc.freenode.net.
