I need to build 32 bit apps the same way as they would be built on i386. When I run 64-bit gcc I get this: gcc -m32 -o m m.c /usr/bin/ld: skipping incompatible /usr/lib/libgcc.a when searching for -lgcc /usr/bin/ld: skipping incompatible /usr/lib/libgcc.a when searching for -lgcc /usr/bin/ld: cannot find -lgcc When I run 32bit gcc I get this: /gcc-4.5.0-32/bin/gcc -m32 -o m m.c /var/tmp//ccif89DB.s: Assembler messages: /var/tmp//ccif89DB.s:11: Error: suffix or operands invalid for `push' /var/tmp//ccif89DB.s:14: Error: `-12(%ebp)' is not a valid 64 bit base/index expression In first case libgcc.so isn't found, and specifying -L/usr/lib32 doesn't help. In the second case 32bit compiler runs 64-bit assembler which is wrong. Is there a documentation how to cross compile 32 bit apps on 64 bit platform? Yuri
