Google Summer of Code/2014/Ideas/Embedded Gentoo using musl
This project involves integrating an alternative standard C library called musl into Gentoo, both for cross compiling and native compiling. Musl aims to be "lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety."  So far, stage4 tarballs have been built for amd64 , i686  and armv7a-hardfloat-eabi . These were initially built using cross compiling toolchians which themselves were built using crossdev , but then were rebuilt on native hardware using home grown scripts , and not catalyst . Picking up from here, the next steps in the project are:
- To build cross compiling toolschains for mips32r2-o32, mipsel3-o32 and mips64r2-n32 architectures/abis. This will involve properly intergrating musl with crossdev which currently has some bugs .
- To build stage 4 tarballs for the those architectures. This involves, among other things, patching various packages that don't conform to strict POSIX which musl assumes .
- These stages need to be converted to stage3's, properly built using catalyst rather than using the ROOT=rootfs emerge -e @system technique which the homegrown scripts use.
- If all goes well, the project can continue to porting over the hardened tool chain to those architectures .
