Package: netgen
Version: 4.4-8
Usertags: ftbfs-gcc-4.3
Your package fails to build with GCC 4.3. Version 4.3 has not been
released yet but I'm building with a snapshot in order to find errors
and give people an advance warning. In GCC 4.3, the C++ header
dependencies have been cleaned up. The advantage of this is that
programs will compile faster. The downside is that you actually
need to directly #include everything you use (but you really should
do this anyway, otherwise your program won't work with any compiler
other than GCC). There's some more information about this at
http://www.cyrius.com/journal/2007/05/10#gcc-4.3-include
You can reproduce this problem with gcc-snapshot from unstable. Note
that Red Hat, Novell and Ubuntu have done some work getting packages
to build with GCC 4.3 so there might be patches floating around
somewhere. I suggest you talk to your upstream.
