[Pkg-octave-devel] Bug#421218: FTBFS with GCC 4.3: must #include <typeinfo> before using typeid

[Martin Michlmayr]

Package: octplot
Version: 0.3.9-3
Usertags: ftbfs-gcc-4.3
Tags: patch

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).

You can reproduce this problem with gcc-snapshot (20070422-1 or higher)
from unstable. (Currently not available for i386, but for amd64 and
and ia64.  I hope to have i386 binaries in the archive in the near
future.)
