make 3.79 or newer
You need the latest version of GNU
make. Modifying the GNU C
Library to work with other
make programs would be so difficult that we
recommend you port GNU
make instead. Really. We
recommend version GNU
make version 3.79. All earlier
versions have severe bugs or lack features.
- GCC 2.95 or newer
The GNU C library can only be compiled with the GNU C compiler family.
As of the 2.2 release, GCC 2.95.2 or higher is required. As of this
writing, GCC 2.95.3 is the compiler we advise to use.
You can use whatever compiler you like to compile programs that use GNU
libc, but be aware that both GCC 2.7 and 2.8 have bugs in their
floating-point support that may be triggered by the math library.
For PPC you might need some patches even on top of the last GCC version.
See the FAQ.
binutils 2.10.1 or later
You must use GNU binutils (as and ld) if you want to build a shared
library. Even if you don't, we recommend you use them anyway. No one
has tested compilation with non-GNU binutils in a long time.
The quality of binutils releases has varied a bit recently. The bugs
are in obscure features, but glibc uses quite a few of those. 2.10.1
and later releases are known to work. Versions after 22.214.171.124.23 may or
may not work. Older versions definitely don't.
For PPC you might need some patches even on top of the last binutils
version. See the FAQ.
To correctly translate and install the Texinfo documentation you need
this version of the
texinfo package. Earlier versions do not
understand all the tags used in the document, and the installation
mechanism for the info files is not present or works differently.
awk 3.0, or some other POSIX awk
Awk is used in several places to generate files. The scripts should
work with any POSIX-compliant awk implementation;
gawk 3.0 and
mawk 1.3 are known to work.
- Perl 5
Perl is not required, but it is used if present to test the
installation. We may decide to use it elsewhere in the future.
sed 3.02 or newer
Sed is used in several places to generate files. Most scripts work with
any version of
sed. The known exception is the script
po2test.sed in the
intl subdirectory which is used to
msgs.h for the testsuite. This script works correctly
only with GNU
sed 3.02. If you like to run the testsuite, you
should definitely upgrade
You may also need these packages if you upgrade your source tree using
patches, although we try to avoid this.
