Introduction to GCC-3.3.6
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-4.1.2 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.

Installation of GCC-3.3.6
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/6.3/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
Command Explanations
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.
Configuring GCC-3.3.6
Configuration information
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.

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.
