I found that the download-able fasm distribution for Linux is only in 32-bit ELF object code form. Therefore, I need to pass -m32 to GCC on my x86_64 multilib system to be able to compile it.

I have just checked and the Linux version does come with an executable called "fasm" and also the fasm.o object. Note that the executable was compiled by fasm and uses SYSCALLs while the object file uses libc instead.

I don't know why the Unix/libc version is now part of the Linux package though, but I'm almost sure that the addition is recent.

yes indeed Wink

. I was just toying around with the object code when I found it cannot be compiled simply with:

gcc -o fasm fasm.o

Does your 64bit linux support 32bit executables (kernel config)?
Does your 64bit linux have 32bit libraries installed?

It's would be better to have binary libs built-in to fasm distributive...
Very Happy

But the Linux package already comes with an executable! If it doesn't work it is because of either you don't have execute permissions on the file or your distro is pure 64 bits.
