I have a heavily templated C++ program (w/ macros too), written by someone else, which compiles and runs using an earlier version of g++ (but not by me). I have managed to find a number of tweeks (this-> additions) which enable the compile to move along. However, I am stumped at the moment. I have used -E, -Q, -dy, and -save-temps options to g++, but the info obtained is not quite enough. I could use something that would dump the source code file name, line number, name of syntactic element observed (e.g., template, non-type template-parameter, template specialization, etc.) and the source text snippet at that point. This is just an aid so that I can be sure that the compiler and I are thinking about the same thing in the same way. The output could be spit out as an xml file. XSLT post-processor tools would spring up to handle that format. Does this exist already? If not, what piece of gcc compiler code would I hack to product this output? Thanks for any replies. BobG
