[Nix-dev] Extra dependencies for Steam games?

[Mike Cooper]

Thanks for the replies everyone. As for the meta issue, I think that having
a steam package that is compatible with all games is a good idea, instead
of requiring overrides.

Unfortunately, it didn't seem to have worked. I tried adding mesa, which
seems to contain the missing library) to each of commonTargetPkgs and
multipkgs in turn, but neither makes the error when launching the game go
away.

To try and debug this further, I ran steam through strace and saw these
lines:

[pid  2646] write(3, "/usr/bin/uname: error while load"..., 124 <unfinished

[pid  2901] +++ exited with 127 +++

It looks to me that it is looking in the wrong place for the library,
looking in the lib directory of glibc, not mesa.

Any ideas?
