[Nix-dev] wine on x86_64, and x86_64 in general

[Lluís Batlle]

I'd like to use wine in an x86_64 machine... I understand it may not
be possible to do that.
What I get building is, in config.log (configure fails):
configure:2814: checking for C compiler default output file name
configure:2836: gcc -m32    conftest.c  >&5
/nix/store/7w2acjgalb0cm7b3bg8yswza4l7iil9y-binutils-2.18/bin/ld:
skipping incompatible /nix/store/g
3z60ik6aq1wipwmxz8rakb7almcfqdz-gcc-4.2.4/lib/gcc/x86_64-unknown-linux-gnu/4.2.4/libgcc.a
when searc
hing for -lgcc
/nix/store/7w2acjgalb0cm7b3bg8yswza4l7iil9y-binutils-2.18/bin/ld:
cannot find -lgcc
collect2: ld returned 1 exit status

I think "-m32" creates 32bit executables, which should be able to run
in an x86_64 environment, isn't it?

Regarding x86_64 in general... aren't other distros making tricks on
libraries, trying to get 32-bit and 64-bit libraries for all the
system? I only heard that, and I don't know how 64bits cope with
32bits... so I'd like some light on that. I think, for example, that
people run 'skype' in 64-bit OSs having a bunch of 32bit libraries
(some X client libraries I guess, as the X protocol may be the same).
How linux copes with 32-bit executables, I don't know at all.
If it were the case, shouldn't nix have a good way of dealing with 32
and 64bit libraries installed at once?

Can anyone help me a bit, maybe sending a link to a document
explaining about that?

Thank you in advance,
Lluís.
