| 8 | <para>This package is known to behave badly when you have changed its
|
|---|
| 9 | default optimization flags (including the -march and -mcpu options). GCC is
|
|---|
| 10 | best left alone. Therefore, if you have defined any environment variables
|
|---|
| 11 | that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
|---|
| 12 | recommend unsetting or modifying them when building GCC. You have
|

| 13 | been warned.</para>

| 15 | <para>Install GCC by running the following commands. These commands will
|

| 16 | build the C and C++ compilers, so you'll need to unpack both the gcc-core
|

| 17 | and gcc-g++ tarballs. Other compilers are available in the full gcc package;
|

| 18 | instructions for building them may be found at
