[Pkg-scicomp-devel] Bug#454883: FTBFS with GCC 4.3: duplicate function parameters & co

[Martin Michlmayr]

Package: gmsh
Version: 2.0.8-3
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.  GCC 4.3 now prints an error
message when C++ code contains duplicate function parameter names in
function prototypes, see
http://www.cyrius.com/journal/2007/12/07#gcc-4.3-multiple-params

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.
