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.

<title>Installation of GCC on the normal system if necessary</title>

|

<para>
|
||||
In order to compile Glibc-2.1.3 later on you need to have gcc-2.95.2.1
|
||||
installed. Although any GCC version above 2.8 would do, 2.95.2.1 is the
|
||||
highly recommended version to use. egcs-2.91.x is also known to work. If you
|
||||
don't have gcc-2.95.x or egcs-2.91.x you need to install gcc-2.95.2.1 on
|
||||
your normal sytem before you can compile Glibc later in this chapter.
|
||||
</para>
|

|

<para>

To find out which compiler version your systems has, run the

following command:

<para>
|

If you normal Linux system does not have gcc-2.95.x or egcs-2.91.x
|
||||
installed you need to install it now. We won't replace the current
|
||||
compiler on your system, but instead we will install gcc in a separate
|
||||
directory (/usr/local/gcc29521). This way no binaries or header files will be
|
||||
replaced.
