<userinput>--with-local-prefix:</userinput> GCC installs a number of
|
|
files in /usr/local even when --prefix is set to something else. We
|
|
don't want that to happen in this case so that's why we use the
|
|
--with-local-prefix option to change that path.

<userinput>--with-gxx-include-dir:</userinput> GCC installs the C++
|
|
header files in /usr/include/g++ by default. Again, in this case we
|
|
don't want that to happen, we want this GCC version to be installed
|
|
completely under /usr/local/gcc2952.

<userinput>make bootstrap:</userinput> Compile GCC by bootstrapping it.
|
|
Here that means the compiler will be built three times in total. First
|
|
it is compiled with your system's default compiler (which will usually
|
|
be a gcc or egcs compiler). This is stage 1 compiler. Then GCC will re-compile
|
|
itself but instead of using your system's compiler it will use itself to
|
|
compile itself again. This is the stage 2 compiler. Then it will compile
|
|
itself a second time with the stage 2 compiler and compares the second
|
|
and the third build to see if they are identical. If so, the
|
|
compilation was a success.
