32bit compilation on 64bit machine?

[angoyal]

why won't my bloody 32bit compilation work on a 64bit box?

$ cat hello32.c
#include <stdio.h>

int
main()
{
printf("Hello\n");
return 0;
}

$ gcc -m32 hello32.c -lc
/usr/bin/ld: crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status

$ gcc -m32 hello32.c
/usr/bin/ld: crt1.o: No such file: No such file or directory
collect2: ld returned 1 exit status

Check that LD_LIBRARY_PATH has the 32 bit libraries before the 64 bit ones so that the thing is linked with the correct libs, and that those libs can be found at all.

How mixed 32 and 64 bit libraries and programs are handled is distribution specific, so best to ask help with this by your distro's help sources.
