     40<title>Re-adjusting the toolchain</title>
     41<?dbhtml filename="adjustingtoolchain.html" dir="chapter05"?>
     42
     43<para>Now that we have compiled all the necessary tools, it is time to
     44re-adjust our toolchain. We will set it up so that it will link any newly
     45compiled program against the new Glibc, which is the first thing to get
     46compiled in the next chapter. Basically, this is the reverse of what we did
     47in the "Locking in" stage in the beginning of this chapter.</para>
     48
     49<para>The first thing to do is to adjust the linker scripts. For this we
     50retained the <filename>binutils-build</filename> directory from the second
     51pass over Binutils. Do the following:</para>
     52
     53<para><screen><userinput>cd binutils-build
     54make -C ld INSTALL=/stage1/bin/install install-data-local</userinput></screen></para>
     55
     56<para>This installs the adjusted linker scripts. The linker scripts now contain
     57no mention of <filename>/stage1/lib</filename>. From now on every compiled
     58program will link <emphasis>only</emphasis> against the libraries in
     59<filename>/usr/lib</filename> and <filename>/lib</filename>. The extra
     60<userinput>INSTALL=/stage1/bin/install</userinput> is needed because the
     61Makefile created during the second pass still contains the reference to
     62<filename>/usr/bin/install</filename>, which we obviously haven't installed
     63yet.</para>
     64
     65<para>You can now remove the Binutils source and build directories.</para>
     66
     67<para>The next thing to do is to amend our GCC specs file so that it points to
     68the new dynamic linker. Just like earlier on, we use a sed to accomplish
     69this:</para>
     70
     71<para><screen><userinput>CURRENTSPECFILE=/stage1/lib/gcc-lib/*/*/specs
     72sed -e 's@/stage1/lib/ld.so.1@/lib/ld.so.1@g' \
     73&nbsp;&nbsp;&nbsp;&nbsp;-e 's@/stage1/lib/ld-linux.so.2@/lib/ld-linux.so.2@g' \
     74&nbsp;&nbsp;&nbsp;&nbsp;$CURRENTSPECFILE > newspecfile
     75mv newspecfile $CURRENTSPECFILE
     76unset CURRENTSPECFILE</userinput></screen></para>
     77
     78<para>Again, cutting and pasting the above is recommended. And just like
     79before, it is a good idea to check the linker scripts and the specs file to
     80ensure the intended changes were actually made.</para>
     81
     82<para>Note that the linker scripts will still contain a reference to
     83<filename>/stage1/i686-pc-linux-gnu/lib</filename>. This is unavoidable, but
     84luckily does not present a problem. There are no libraries in that location
     85as all the temporary stage1 libraries are located in
     86<filename>/stage1/lib</filename>.</para>
