Workaround for when PatchELF fails?

[chris-martin]

Sorry if this question is off-topic, but I figure anyone working on this project would know the answer (and anyone using this project probably could benefit from the answer).

I'm trying to run Otto on NixOS and I'm blocked by issues #38 and/or #66. So I'm wondering what are the alternatives to PatchELF in cases where it doesn't work?

The only workaround I've come up with so far is to symlink ld-linux-x86-64.so.2 from /nix/store/... to /lib64/, which is pretty ugly.

It should be possible to run a binary directly with /nix/store/<...>/ld-linux-x86-64.so.2 /nix/store/<...>/<program>. You might have to overwrite the LD_LIBRARY_PATH variable too.

When I run nix/store/.../ld-linux-x86-64.so.2 ./otto, it halts immediately with no output.

In case this is of any help:

> /nix/store/.../ld-linux-x86-64.so.2 --list ./otto
        linux-vdso.so.1 (0x00007ffc9c7c3000)
        libpthread.so.0 => /nix/store/.../libpthread.so.0 (0x00007febb77c9000)
        libc.so.6 => /nix/store/.../libc.so.6 (0x00007febb7429000)
        /lib64/ld-linux-x86-64.so.2 => /nix/store/.../ld-linux-x86-64.so.2 (0x00007febb79e6000)

Very anecdotal, but what @darealshinji said in #68 (comment) worked for me. I ended up using a wrapper to the effect of exec $(cat $NIX_CC/nix-support/dynamic-linker) $orig $@.
