As the comment says, GCC2 compiled for x86_64 is broken on most systems, including Ubuntu (it errors out with the "cast specifies signature type" when built that way.)

The errors are because you didn't install the libc32-devel package on Ubuntu. I think the readme already tells you to have a 32-bit compiler, yes? So thkis is invalid.

Thanks for the explanation. I don't see which readme you're referring to. At least the issue is here for anyone searching for it.
