<title>Installation of GCC</title>
|
|
|
|
<para>This package is known to behave badly when you have changed its default
|
|
optimization flags (including the -march and -mcpu options). GCC is best
|
|
left alone, so we recommend you unsetting CFLAGS, CXXFLAGS and other
|
|
such variables/settings that would change the default optimization that
|
|
it comes with.</para>
