I guess that's the only thing you can do with a static executable (using static libc is bad enough by itself). Of course, you can feign the paths by some chroots, proot or VM.

(Is > this expected?) Same thing, LD_PRELOAD doesn't work with static binaries because it affects the dynamic linker, which doesn't get used for static executables. If there is a dynamic executable hidden inside the static executable via UPX compression or something similar, I guess you need to decompress it first and then apply patchelf. -- Eelco Dolstra | LogicBlox, Inc. | http://nixos.org/~eelco/ ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
Re: [Nix-dev] Static Executable: Patchelf fails me
Not an expert here, but maybe the binary is so much stripped that patchelf
is not able to determine the right offsets for patching the binary.
About the segfault, maybe it spawns some other process and the libs are not
propagated? That may explain why the symlink works.
