Short Descriptions
The GCC-3.3.6 package contains the gcc-3.3.6 C and C++ compilers and the GCC-3.3.6 libstdc++.so library that is required by some commercial and pre-compiled packages.
There are several reasons why you may wish to install GCC-3.3.6. Some packages have not been updated so they can be successfully compiled by GCC-4.0.3 as version 4.x.x of GCC is much stricter in enforcing coding standards. Additionally, some pre-compiled packages may require the GCC-3.3.6 libraries at run-time. Another reason you may need to install GCC-3.3.6 is to use the g77 Fortran 77 compiler provided by pre-4.x.x versions of GCC. GCC-4.x.x only includes gfortran, a Fortran 95 compatible compiler that is not yet ready to be used in a production environment.
If all you need is a working {f,g}77 Fortran 77 compiler, you may wish to use the one provided by GCC-3.4.x. This is what the GCC developers recommend. Instructions for building the GCC-3.4.x Fortran compiler can be found on the BLFS Wiki.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/gcc3
Install GCC-3.3.6 by running the following commands:
patch -Np1 -i ../gcc-3.3.6-no_fixincludes-1.patch && patch -Np1 -i ../gcc-3.3.6-linkonce-1.patch && mkdir ../gcc-build && cd ../gcc-build && ../gcc-3.3.6/configure --prefix=/opt/gcc-3.3.6 \ --enable-shared --enable-languages=c,c++ --enable-threads=posix && make bootstrap
If desired, run the test suite using the following commands. The test_summary commands create log files which can be compared to known good results located at http://anduin.linuxfromscratch.org/files/BLFS/gcc336_test.txt.
make -k check && ../gcc-3.3.6/contrib/test_summary >test_summary.log 2>&1 && ../gcc-3.3.6/contrib/test_summary | \ grep -A7 Summ >test_summary_short.log 2>&1
Now, as the root user:
make install && mv -v /opt/gcc-3.3.6/lib/libstdc++.so.5* /usr/lib && ln -v -sf /usr/lib/libstdc++.so.5.0.7 /opt/gcc-3.3.6/lib && ln -v -sf libstdc++.so.5.0.7 /opt/gcc-3.3.6/lib/libstdc++.so.5 && chown -v -R root:root \ /opt/gcc-3.3.6/lib/gcc-lib/i686-pc-linux-gnu/3.3.6/include
mkdir ../gcc-build; cd ../gcc-build: The GCC development team recommends building in a separate directory.
--enable-shared --enable-languages=c,c++ --enable-threads=posix: Configures GCC to build the C and C++ compilers and enable the related C++ options. In addition to c and c++, you can add f77 for FORTRAN (called g77). Note that GCC-4 no longer provides a FORTRAN 77 compiler.
mv -v /opt/gcc-3.3.6/lib/libstdc++.so.5* /usr/lib: Moves the C++ library to the standard lib directory to avoid having to add /opt/gcc-3.3.6/lib to /etc/ld.so.conf.
If you only need the GCC-3.3.6 C++ library, you may delete /opt/gcc-3.3.6.
Whenever you need to use GCC-3.3.6 instead of your system installed compiler, add /opt/gcc-3.3.6/bin to the front of your PATH or (preferably) set the CC environment variable before compiling the concerned package.
If you use g77 programs, you also should move the libg2c.* libraries and symbolic links to /usr/lib. Using export LD_LIBRARY_PATH=/opt/gcc-3.3.6/lib or updating /etc/ld.so.conf to point to /opt/gcc-3.3.6/lib is not recommended as it may conflict with your normal libraries.
