Hi,

When compiling the util-linux-2.12q sources, I get the following linker
ABI incompatibility error:

[alex@euskadi util-linux-2.12q]$ make

This package compiles completely if I use an -mabi=n32 flag for gcc, but the executable won't run on our -mabi=32 compiled kernel.

Can anybody help with the following:

1) What's the difference between -mabi=32 and -mabi=n32?
2) What should I do to compile util-linux with -mabi=32?

Thanks,
Alex
