O32 and N32 are both 32 +bits, but they have different calling conventions, and alignment +constraints, and similar. The N32 format is the default format from IRIX +6.4. + +You select ABI at compile time, and you can do this with the +@samp{--with-mips-abi} configure option. The valid arguments are +@samp{o32}, @samp{n32}, and @samp{64}, N32 is the default. Libraries for +the three different ABI:s are normally installed installed in different +directories (@samp{lib}, @samp{lib32}, and @samp{lib64}). If you want +more than one set of libraries you have to reconfigure and recompile for +each ABI, but you should probably install only N32 binaries. + +@cindex GCC +GCC had had some known problems with the different ABI:s.
