Make sure you have installed the following packages as well:-
1. libstdc++.i386
2. libgcc.i386
3. glibc.i386
4. glibc-devel.i386

I faced this error when using ” gcc -m32 -o de ‘/home/atieh/Desktop/debug.o” of course my program is not only in C languge , it ’s embbeded with assembly.
here is the error:
skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.3/libgcc.a when searching for -lgcc
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.3/libgcc.a when searching for -lgcc
/usr/bin/ld: cannot find -lgcc
collect2: ld returned 1 exit status

I found this:
you might want to install glibc-devel.i386 (even if you’re on x64) to fix this problem
and this:
On ubuntu 64-bit version, solution is:
sudo apt-get install g++-multilib

hope that will solve it.

I get a similar error as Vlad:
In file included from /usr/include/features.h:352,
from /usr/include/stdio.h:28,
from slu_util.h:4,
from slu_sdefs.h:28,
from sgssv.c:9:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory

Anyone?

Try giving build info to autoconf.
for a one line solution,
$> env CFLAGS=”-m32″ LDFLAGS=”-m32″ ./configure –build=i686-unknown-linux-gnu …

Any ideas how to convince the average ./configure to compile in 32 bit mode? I’m trying to compile pcsx2 (a PS2 emulator) in 32 bit mode because apparently it works better. I did

export CFLAGS=-m32
export CXXFLAGS=-m32

beforehand, and building stuff works. However the problem is that configure correctly realises I’m using a 64 bit processor and set lots of #defines and other things (such as choosing the x86-64 version of an assembly file). This messes up the build. God I hate autotools.

vlad – you need to install gcc multilib for your distribution – it should then compile O.K.

How can I build x64 target. using -m64 gives error. how can I download the libraries for 64 bit. remember I am using ubuntu and gcc 4.1.2.

looks like by default gcc compiles x86.

I got this error trying to compile with -m32 :S
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h

Whats wrong?

Thanks for heads up!

I think
gcc -m32 -o output64 hello.c

should be
!
gcc -m32 -o output32 hello.c

and

$ gcc -m64 -o output64 hello.c

should be

$ gcc -m64 -o output64 hello.c
