     11
     12<para>The last patch changes GCC's default location of the dynamic linker,
     13a simple substitution of "/lib/ld-linux.so.2" with "/stage1/lib/ld-linux.so.2"
     14in <filename>config/i386/linux.h</filename>. Patching now rather than adjusting
     15the specs file after installation ensures that our new dynamic linker gets
     16used during the actual build of GCC. That is, all the final (and temporary)
     17binaries created during the build will link against the new Glibc.</para>

     32<para>Compile the package:</para>
     33
     34<para><screen><userinput>make</userinput></screen></para>
     35<para>There is no need to use the <userinput>bootstrap</userinput> target now,
     36as the compiler we're using to compile this GCC has been built from the exact
     37same sources.</para>
     38
     39<para>Test the package:</para>
     40
     41<para><screen><userinput>make -k check</userinput></screen></para>
     42
     43<para>The <userinput>-k</userinput> flag is used to make the test suite run
     44through to completion and not stop at the first failure. The GCC test suite is
     45very comprehensive and is almost guaranteed to generate a few failures. To get
     46a summary of the test suite results, run this:</para>
     47 
     48<para><screen><userinput>../gcc-3*/contrib/test_summary | less</userinput></screen></para>
     49
     50<para>You can compare your results to those posted to the gcc-testresults
     51mailing list for similar configurations to your own. For an example of how
     52current GCC-3.2.x should look on i686-pc-linux-gnu, see
     53<ulink url="http://gcc.gnu.org/ml/gcc-testresults/2003-02/msg00204.html"/>.</para>
     54
     55<para>Note that the results contain:</para>
     56
     57<screen>* 1 XPASS (unexpected pass) for g++
     58* 26 XPASS's for libstdc++
     59* 1 FAIL for libstdc++</screen>
     60 
     61<para>The unexpected pass for g++ is due to the use of
     62<userinput>--enable-__cxa_atexit</userinput>. Apparently not all platforms
     63supported by GCC have support for "__cxa_atexit" in their C libraries, so this
     64test is not always expected to pass.</para>
     65
     66<para>The 26 unexpected passes for libstdc++ are due to the use of
     67<userinput>--enable-clocale=gnu</userinput>, which is the correct choice on
     68Glibc-based systems of versions 2.2.5 and above. The underlying locale support
     69in the GNU C library is superior to that of the otherwise selected "generic"
     70model (which may be applicable if for instance you were using Newlibc, Sun-libc
     71or whatever libc). The libstdc++ test suite is apparently expecting the
     72"generic" model, hence those tests are not always expected to pass.</para>
     73
     74<para>The failure for libstdc++ is in
     75<filename>26_numerics/c99_classification_macros_c.cc</filename> and is a
     76long-standing known failure (since at least January 2002) that the developers
     77are apparently unable to easily fix.</para>
     78
     79<para>And finally install the package:</para>                                             
     80
     81<para><screen><userinput>make install</userinput></screen></para>
