> If you do not know what glibc is by now, don't worry! When I
|
|
first had problems with a new program I wanted to compile, I only
|
|
knew that my version of glibc was not sufficient for the
|
|
compile. Now that I know more, I will try to explain in a very simple way what
|
|
glibc does.</P
|
|
><P
|
|
>The glibc package contains a library written in the
|
|
programming language of C. Libraries are a very useful thing in programming;
|
|
instead of inventing the wheel from scratch for operations such as
|
|
computing the square-root of a number, such common functions
|
|
are stored in separate files—the so-called libraries.
|
|
When a new version of a library is published it often contains
|
|
some new functions, uses more efficient algorithms for already
|
|
implemented functions, and so on.</P
|
|
><P
|
|
>This is the reason why some programs complain about an older
|
|
version of glibc: the current version just does not contain all the functions
|
|
the program needs in order to run.</P
|
|
><P
|
|
>I know this is not technically correct in all detail, but it
|
|
gives you a basic understanding of the architecture behind.</P
