ANN: gcc-python-plugin 0.11
by David Malcolm 05 Dec '12

05 Dec '12

gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the CPython interpreter within GCC, allowing you to write new compiler warnings in Python, generate code visualizations, etc. It ships with "gcc-with-cpychecker", which implements static analysis passes for GCC aimed at finding bugs in CPython extensions. In particular, it can automatically detect reference-counting errors: http://gcc-python-plugin.readthedocs.org/en/latest/cpychecker.html What's new in 0.11? =================== The main change in this release is support for compiling the plugin with a C++ compiler. Recent versions of GCC 4.7 are now built with C++ rather than C, meaning that plugins must also be built with C++ (since all of GCC’s internal symbols are name-mangled). This release fixes the plugin’s Makefile so that it autodetects whether the plugin needs to be built with a C or C++ compiler and (I hope) does the right thing automatically. I've also made the necessary changes to the C source code of the plugin so that it is compilable as either language. This should enable the plugin to now be usable with recent builds of gcc 4.7.* (along with gcc 4.6). The plugin doesn't yet support gcc 4.8 prereleases (help would be appreciated!) For a description of the other improvements in 0.11, detailed release notes can be seen at: http://gcc-python-plugin.readthedocs.org/en/latest/0.11.html Tarball releases are available at: https://fedorahosted.org/releases/g/c/gcc-python-plugin/ Prebuilt-documentation can be seen at: http://gcc-python-plugin.readthedocs.org/en/latest/index.html The project's homepage is: https://fedorahosted.org/gcc-python-plugin/ The plugin and checker are Free Software, licensed under the GPLv3 or later. Enjoy! Dave Malcolm

Plans for C++ Code

Hi all, Are there any plans to port this plugin to C++?[0] I haven't been able to roll out the Gentoo ebuild for gcc-python-plugin-0.10 because my GCC 4.7.[12] is built with C++ so there are plenty symbol mismatches.

Yes, I am certain on my systems :-) I am not interested in installing a complete new distro only for checking one library. And I believe that missing only one symbol should not be a such big deal. But I think it is to much work that you have to install a new distro only for fixing my problems! It is not so important for me to get the things run and I could check out another distro on my colleagues desktops in the next week. My gcc was build with: ../configure --prefix=/opt/linux-gnu_4.7.2 --with-mpfr=/opt/linux-gnu_4.7.2 --with-mpc=/opt/linux-gnu_4.7.2 --with-ppl=/opt/linux-gnu_4.7.2 --with-gmp=/opt/linux-gnu_4.7.2 --enable-languages=c,c++ Thanks a lot for contribute your time for my problem!

Sorry you had to endure this. I just updated the wiki to indicate that dehydra/treehydra are dead. See https://developer.mozilla.org/en-US/docs/Dehydra. Try the python gcc plugin instead.
