Package: libglu1-xorg
Version: 6.8.2.dfsg.1-3
Severity: wishlist
Tags: patch

The X.org implementation of libGLU is coded in C++, but it is intended
to expose only C interfaces.  At present, many of the internal
interfaces are visible in the dynamic symbol table of the shared library,
which means that people may accidentally use them.  A version script should
be applied to hide these internal symbols.  [This is true for all
the X libraries, but it's especially important for libGLU because Debian
is assuming that libGLU need not participate in the C++ ABI transition
because the C++ symbols are internal only.]

I have prepared a crude patch which does this; please find attached
064_libGLU_symbol_versions.diff.  It uses the existing list of exports
(GLU-def.cpp) to generate the version script, which may well be wrong;
someone who knows what libGLU's external interfaces are should check this
carefully.  Also, my Imake-fu is nonexistent, so I have kludged the
map generation and application into xc/lib/GLU/Imakefile rather than doing
something that could be applied to the other libraries.  For these reasons
I don't suggest applying this verbatim; please consider it a starting point.
(Sequence number 064 was arbitrarily chosen, by the way.  It doesn't much
matter - nothing else seems to touch those files.)
