From 0d44b5b7733e35fe17b34921c611c21f805068a9 Mon Sep 17 00:00:00 2001 From: Alyssa Ross Date: Thu, 23 Nov 2023 12:28:49 +0100 Subject: pkgsStatic.stdenv: fix custom CMake LINKER_LANGUAGE If a CMake target has a non-default LINKER_LANGUAGE set, CMake will manually add the libraries it has detected that language's compiler as linking implicitly. When it does this, it'll pass -Bstatic and -Bdynamic options based on the vibes it gets from each such detected library. This in itself isn't a problem, because the compiler toolchain, or our wrapper, or something, seems to be smart enough to ignore -Bdynamic for those libraries. But it does create a problem if the compiler adds extra libraries to the linker command line after that final -Bdynamic, because those will be linked dynamically. Since our compiler is static by default, CMake should reset to -Bstatic after it's done manually specifying libraries, but CMake didn't actually know that our compiler is static by default. The fix for that is to tell it, like so. Until recently, this problem was difficult to notice, because it would result binaries that worked, but that were dynamically linked. Since e08ce498f03f ("cc-wrapper: Account for NIX_LDFLAGS and NIX_CFLAGS_LINK in linkType"), though, -Wl,-dynamic-linker is no longer mistakenly passed for executables that are supposed to be static, so they end up created with a /lib interpreter path, and so don't run at all on NixOS. This fixes pkgsStatic.graphite2. --- pkgs/stdenv/generic/make-derivation.nix | 2 ++ 1 file changed, 2 insertions(+) (limited to 'pkgs/stdenv') diff --git a/pkgs/stdenv/generic/make-derivation.nix b/pkgs/stdenv/generic/make-derivation.nix index 63d02c8f0857..faa83507893f 100644 --- a/pkgs/stdenv/generic/make-derivation.nix +++ b/pkgs/stdenv/generic/make-derivation.nix @@ -427,6 +427,8 @@ else let "-DCMAKE_HOST_SYSTEM_VERSION=${stdenv.buildPlatform.uname.release}" ] ++ optionals (stdenv.buildPlatform.canExecute stdenv.hostPlatform) [ "-DCMAKE_CROSSCOMPILING_EMULATOR=env" + ] ++ lib.optionals stdenv.hostPlatform.isStatic [ + "-DCMAKE_LINK_SEARCH_START_STATIC=ON" ]); mesonFlags = -- cgit 1.4.1
