cmake/setup-hook.sh: Don't skip build-RPATH #108496

knedlsepp · 2021-01-05T17:05:14Z

Motivation for this change

This should simplify using nix-shell -A or nix develop to develop
CMake based projects. CMake features a mechanism to use a different
RPATH for all executables in the build directory and only rewrite these
RPATHs on installation. This makes it possible to run executables
already from the build directory without having to set LD_LIBRARY_PATH.
This should simplify the checkPhase for cmake based projects and
hopefully not break anything.

Fixes: #22060

👍 Currently stuck at building bluez with this anyway.

Darwin stdenv still builds with this fyi

Thanks for the heads up. I'll try to figure out what was my issue with the bluez build then we can move this forward.

stale · 2021-07-26T14:24:26Z

I marked this as stale due to inactivity. → More info

knedlsepp · 2021-07-26T16:25:40Z

After #123011 was merged I can build bluez and continue with this.

knedlsepp · 2021-07-26T19:07:40Z

For reference. The last attempt was reverted because of #15881

knedlsepp · 2021-07-26T19:17:23Z

cc @ttuegel You once tried to drop the SKIP_BUILD_RPATH in 8ec5adc, which had to be reverted in d5d4606 because of a broken Darwin stdenv.
I'd like to try again to get rid of it since it's somewhat of an inconvenience that by default tests in cmake builds don't work unless you set LD_LIBRARY_PATH or disable the SKIP_BUILD_RPATH.

I tried nixpkgs-review on this, but it requires downloading 128GB of stuff, so I just rebuilt the projects on a best effort basis and everything seems to work fine on x86_64-linux.

Metis hasnt been updated in nixpkgs since 2015 so either lets mark it broken or try updating it or set the cmake flag removed here for it

@danshapero also @jtojnar due to him having created an issue in https://github.com/KarypisLab/METIS

MatthewCroughan · 2022-07-12T06:40:25Z

I can confirm that spirv-llvm-translator was broken on staging-next, as I ran into this specific issue when trying to use staging-next to cross compile an sdImage for riscv64.

My program (quick-lint-js) successfully installs with Nix on Linux. However, due to this patch, the installed executable can't find libstdc++.so.6.

I don't know if this bug happens with other programs.

How should I work around this problem?

Notice how the gcc-11.3.0-lib runpath entry is missing from the executable after this patch:

Nixpkgs commit e1e0d5d (after this patch was merged):

$ nix-shell -I ~/Projects/ -p quick-lint-js --run 'quick-lint-js --version'
quick-lint-js: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory

$ readelf -a "$(nix-shell -I ~/Projects/ -p quick-lint-js --run 'which quick-lint-js')" | egrep -i 'r(un)?path'
 0x000000000000001d (RUNPATH)            Library runpath: [/nix/store/mhhlymrg2m70r8h94cwhv2d7a0c8l7g6-glibc-2.34-210/lib]

Nixpkgs commit de1ff46 (before this patch was merged):

$ nix-shell -I ~/Projects/ -p quick-lint-js --run 'quick-lint-js --version'
quick-lint-js version 2.6.0

$ readelf -a "$(nix-shell -I ~/Projects/ -p quick-lint-js --run 'which quick-lint-js')" | egrep -i 'r(un)?path'

@strager sorry to hear that, I don't see why this change should have broken that. For now, you can manually revert to the old behavior on a per-package basis, which seems to fix the rpath:

--- a/pkgs/development/tools/quick-lint-js/default.nix
+++ b/pkgs/development/tools/quick-lint-js/default.nix
@@ -15,6 +15,10 @@ stdenv.mkDerivation rec {
   nativeBuildInputs = [ cmake ninja ];
   doCheck = true;
 
+  cmakeFlags = [
+    "-DCMAKE_SKIP_BUILD_RPATH=ON"
+  ];

Turning on CMAKE_BUILD_WITH_INSTALL_RPATH also seems to fix it, so it seems there is something wrong with the rpath rewriting for this package.

i tried autoPatchelfHook and first got

quick-lint-js> auto-patchelf failed to find all the required dependencies.
quick-lint-js> Add the missing dependencies to --libs or use `--ignore-missing="foo.so.1 bar.so etc.so"`.

then added stdenv.cc.cc.lib to buildInputs and then it works

autoPatchelfHook is usually used for random binaries from other distros so its not the proper fix for this case
