gccxml attempts to simulate the preprocessor of the target compiler, but it cannot simulate the ABI correctly because it was built only for one target system. In cases like this the target software likely needs to be taught about __GCCXML__ just as any other compiler. -Brad _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Follow this link to subscribe/unsubscribe: http://www.gccxml.org/mailman/listinfo/gccxml
