Building a GCC PowerPC/Linux Cross Compiler For SPARC/Solaris[5]

fix up

once you have successfully built and installed everything, there are a few minor fix ups that need to be done to complete the installation. the primary outcome of the following steps is to remove the duplicate copies of the target headers and libraries and to permanent copy in the linux headers. if you do not want to do this, you can safely skip this step.

1. cd <tool dir>/host/sparc-sun-solaris/powerpc-linux/
2. rm -f include/asm
3. rm -f include/linux
4. rm -rf include/
5. mv lib/ldscripts lib/nof lib/libstdc++-* <tool dir>/target/powerpc-linux-gnu/lib
6. rm -f lib/ sys-include/
7. ln -si <tool dir>/target/powerpc-linux-gnu/include include
8. ln -si <tool dir>/target/powerpc-linux-gnu/lib lib
9. ln -si include sys-include
10. mkdir <tool dir>/target/powerpc-linux-gnu/include/asm
11. mkdir <tool dir>/target/powerpc-linux-gnu/include/linux
12. (cd <source dir>/linux/include/asm; tar cf - . | (cd <tool dir>/target/powerpc-linux-gnu/include/asm; tar xfbp -))
13. (cd <source dir>/linux/include/linux; tar cf - . | (cd <tool dir>/target/powerpc-linux-gnu/include/linux; tar xfbp -))
