GCC-XML internally uses a gcc 3.3 parser with some patching to do the xml dump. The way we get this parser to look through the system headers of other compilers is to copy/patch those headers that it cannot read. This has worked for every GCC compiler up through 4.1 because only a few headers need fixing. Unfortunately the system headers that come with 4.2 *all* use a syntax that is not supported by the 3.3 parser. I'm currently working on upgrading the internal parser to be the gcc 4.2 parser. Upgrading to a 4.x parser internally has been a long-requested feature anyway. However I do not know when I will be able to finish this upgrade. It is a *major* update. The work-around for you is $ sudo apt-get install g++-4.1 $ gccxml main.cpp -fxml=test.xml --gccxml-compiler g++-4.1 -Brad _______________________________________________ gccxml mailing list [email protected] http://www.gccxml.org/mailman/listinfo/gccxml
