MIPS clarification: o32 ABI (32bit) -> /lib n32 ABI (32bit w/ full access to 64bit address space/registers) -> /lib32 n64 ABI (64bit) -> /lib64 In a full-on MIPS multilib, you can have all three folders present and filled with their respective ABI libs/binaries. One ABI will dominate the system, though. Right now, that's still o32, but not for much longer. n32 will become the defacto soon, and o32 will be built only if needed (i.e. a program exhibits issues in n32 until upstream can fix). n64 is also an as-needed basis, typically where a program derives a benefit from being true 64bit versus one of the other two. -- Joshua Kinard Gentoo/MIPS ku...@gentoo.org 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.
