|

5 | In order to compile Glibc-2.1.3 later on you need to have gcc-2.95.2
|
---|
6 | installed. Although any GCC version above 2.8 would do, 2.95.2 is the
|
---|
7 | highly
|
---|
8 | recommended version to use. egcs-2.91.x is also known to work. If you
|
---|
9 | don't have gcc-2.95.x or egcs-2.91.x you need to install gcc-2.95.2 on
|
---|
10 | your normal sytem before you can compile Glibc later in this chapter.

25 | If you normal Linux system does not have gcc-2.95.x or egcs-2.91.x
|
---|
26 | installed you need to install it now. We won't replace the current
|
---|
27 | compiler on your system, but instead we will install gcc in a separate
|
---|
28 | directory (/usr/local/gcc2952). This way no binaries or header files will be
|
---|
29 | replaced.
