Dear DPMT, This is about matplotlib in Lenny to fix bug #492735. I have backported the changes, and myself and Sandro verified that the patch fixes the memory leak, so I uploaded it to testing-proposed-updates. All fine.
However, the package failed to build on ia64, mips and powerpc due to a strange problem. Matplotlib has C and C++ components which are compiled during the build. The strange way the build system works causes gcc to be used to compile C++ code using gcc as well. This results in a strange problem when the versions of gcc and g++ on the buildd are not in sync. See the logs here: http://buildd.debian.org/~jeroen/status/package.php?p=matplotlib&suite=testing I asked upstream about this, and they told me that it wasn't their fault, but that of distutils which uses gcc for C++ as well (they essentially said something to the effect of "wontfix"). I then mailed the buildd maintainers to give back the package with an updated chroot containing equal versions of gcc and g++. However, the give-back occurred without updation of the chroot, and thus, has failed more than once on all architectures except arm, where the buildd in-charge installed the right versions of gcc/g++ before the give back. With the current situation, I don't seem to be able to tell the buildd maintainers to update their chroots, and some queries with regard to this also made me realize that it isn't wise to assume equal versions of gcc and g++. So, I propose an inelegant workarond by prepending CC=g++ before the setup.py call while building the package, which builds everything using g++. That works perfectly, with the small problem of this warning: cc1plus: warning: command line option "-Wstrict-prototypes" is valid for Ada/C/ObjC but not for C++ So, I wanted your suggestion on what would be the right way to fix this bug. Thanks! Kumar -- Kumar Appaiah
