The gcc version requirements may vary depending on the type of CPU in your
|
||||
computer. The next paragraph applies to users of x86 CPUs, but not
|
||||
necessarily to users of other CPUs. Users of other CPUs should obtain
|
||||
information about their gcc version requirements from another source.
|
||||
|
||||
The recommended compiler for the kernel is gcc 2.95.x (x >= 3), and it
|
||||
should be used when you need absolute stability. You may use gcc 3.0.x
|
||||
instead if you wish, although it may cause problems. Later versions of gcc
|
||||
have not received much testing for Linux kernel compilation, and there are
|
||||
almost certainly bugs (mainly, but not exclusively, in the kernel) that
|
||||
will need to be fixed in order to use these compilers. In any case, using
|
||||
pgcc instead of plain gcc is just asking for trouble.
|
||||
|
||||
The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.
|
||||
You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build
|
||||
the kernel correctly.
|
||||
|
||||
In addition, please pay attention to compiler optimization. Anything
|
||||
greater than -O2 may not be wise. Similarly, if you choose to use gcc-2.95.x
|
||||
or derivatives, be sure not to use -fstrict-aliasing (which, depending on
|
||||
your version of gcc 2.95.x, may necessitate using -fno-strict-aliasing).
