<title>Installation of GCC</title>
|
|
|
|
<para>This package requires its patch to be applied before you can
|
|
install it.</para>
|
|
|
|
<para>We won't be needing a C++ compiler until Chapter 6. So, only
|
|
the gcc-core tarball needs to be unpacked at this time.</para>
|
|
|
|
<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. Therefore, if you have defined any environment variables
|
|
that override default optimizations, such as CFLAGS and CXXFLAGS, we
|
|
recommend unsetting or modifying them when building GCC. You have
|
|
been warned.</para>

|
<para>Install GCC by running the following commands:</para>
