Now that the temporary C libraries have been installed, we want all the tools compiled in the rest of this chapter to be linked against these libraries. To accomplish this, we need to adjust the linker's scripts and the compiler's specs file. First install the adjusted linker scripts by running the following from within the binutils-build directory: make -C ld install-data-local These scripts were adjusted a little while back, at the end of the first pass of Binutils, and contain no mention of /lib, /usr/lib or /usr/local/lib. From this point onwards everything will link only against the libraries in /tools/lib. Now that the scripts are adjusted, you have to remove the Binutils build and source directories. The next thing to do is to amend our GCC specs file so that it points to the new dynamic linker. A simple sed will accomplish this: SPECFILE=/tools/lib/gcc-lib/*/*/specs sed -e 's@/lib/ld.so.1@/tools/lib/ld.so.1@g' \     -e 's@/lib/ld-linux.so.2@/tools/lib/ld-linux.so.2@g' \     $SPECFILE > tempspecfile mv tempspecfile $SPECFILE unset SPECFILE We recommend that you cut-and-paste the above rather than try and type it all in. Or you can edit the specs file by hand if you want to: just replace "/lib/ld-linux.so.2" with "/tools/lib/ld-linux.so.2" and "/lib/ld.so.1" with "/tools/lib/ld.so.1". Lastly, there is a possibility that some include files from the host system have found their way into gcc's private include dir. This can happen because of GCC's "fixincludes" process which part of the GCC build. We'll explain more about this further on in this chapter. For now, run the following commands to eliminate this possibility. rm -f /tools/lib/gcc-lib/*/*/include/{pthread.h,bits/sigthread.h} This completes the installation of the self-contained toolchain, which can now be used to build the rest of the temporary tools.
