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 /stage1/lib. You can now remove Binutils' build and source directories. The other 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=/stage1/lib/gcc-lib/*/*/specs sed -e 's@/lib/ld.so.1@/stage1/lib/ld.so.1@g' \     -e 's@/lib/ld-linux.so.2@/stage1/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 "/stage1/lib/ld-linux.so.2". Also, because we allowed GCC's "Fixincludes" script to modify our host's header files (and this was necessary because of improper use of the __thread keyword in some older software), we want to get rid of those modified header files, and replace them with pristine ones. GCCDIR=/stage1/lib/gcc-lib/*/* rm -rf $GCCDIR/include/* cp $GCCDIR/install-tools/include/* $GCCDIR/include cp $GCCDIR/install-tools/gsyslimits.h \ $GCCDIR/include/syslimits.h unset GCCDIR This completes the installation of the self-contained toolchain, which can now be used to build the rest of the temporary tools.
