Re: eglibc fails to build from source



It works !

Is there a good documentation somewhere about the "official" method for building eglibc for debian ?

i was not aware of this way of patching source and the "classical" way (patch, configure) that i used does not show any error although the compilation failed. It is a little misleading for a beginner.

Thanks

A simpler and less error-prone way to unpack the source would be to use
"dpkg-source -x eglibc_2.11.3-2.dsc".

The Debian diff does not patch the source directly, but uses a patch
system named quilt.  You need to install the quilt package and then run
"make -f debian/rules patch".

The unpatched source does not build because Debian had to remove the
documentation, and the upstream build system is not prepared for that.
