@Michael. I am studying in a software reegineering lab - I do have a small clue ;) We had a Masters' student who implemented his own C grammar. 3 months of work for one bullet in one slide. No fun.
I know that C++ is an horrible monster to parse. My question was why pick a tool over another. Maybe the JavaCC or Antlr grammars are not very good. Maybe the Phoenix framework doesn't work for some variants of C++ we care about. Maybe GCC has an horrible API. Maybe nobody feels like asking for a license for the Bauhaus framework. You can tell I've done a lot of guessing in the last paragraph :D Since I am in such a lab, and someone will sooner or later want an improved C/C++ analysis tool, I'd like to give the best suggestion. @Lubos. I started writing a plug-in. I have a problem with compiling, however. It somehow doesn't find the headers on my system. This is the autogen.sh I use (I tried with and without --includedir, and --includedir=/usr/) ./autogen.sh CC=clang CXX=clang++ --includedir=/usr/include/ --enable-compiler-plugins I get this in the output: checking clang/AST/RecursiveASTVisitor.h usability... no checking clang/AST/RecursiveASTVisitor.h presence... no checking for clang/AST/RecursiveASTVisitor.h... no configure: error: Cannot find Clang headers to build compiler plugins. Yet... $ ls /usr/include/clang/AST/RecursiveASTVisitor.h /usr/include/clang/AST/RecursiveASTVisitor.h I am on Linux Mint 14. Any clue what is going on?
