| 6 | <para>This package is known to behave badly when you have changed its
|
|---|
| 7 | default optimization flags (including the -march and -mcpu options).
|
|---|
| 8 | Therefore, if you have defined any environment variables that override
|
|---|
| 9 | default optimizations, such as CFLAGS and CXXFLAGS, we recommend unsetting
|
|---|
| 10 | or modifying them when building GCC.</para>

| 12 | <para>This is an older release of GCC which we are going to install for the
|
|---|
| 13 | purpose of compiling the Linux kernel in Chapter 8. This version is recommended
|
|---|
| 14 | by the kernel developers when you need absolute stability. Later versions of
|
|---|
| 15 | GCC have not received as much testing for Linux kernel compilation. Using a
|
|---|
| 16 | later version is likely to work, however, we recommend adhering to the kernel
|
|---|
| 17 | developer's advice and using the version here to compile your kernel.</para>
