I'm happy to announce CastXML, a successor to GCC-XML .
CastXML is hosted here:
It is a tool based on LLVM/Clang that generates the same
XML output format as GCC-XML . CastXML's design offers
some advantages over GCC-XML's:
1. LLVM/Clang offers a true SDK for external tools,
so CastXML does not need to maintain a fork.
GCC-XML requires significant work to update its
parser to a more recent GCC. CastXML can simply
be built against a recent LLVM/Clang.
2. LLVM/Clang natively supports parsing both GCC and
Visual Studio system headers, so CastXML does not
need to maintain a set of system header patches.
GCC-XML must be updated with system header patches
for each new version of compilers it supports.
CastXML can simply parse the headers directly.
3. CastXML will need little to no work to support newer
GCC and Visual Studio versions as they are released.
LLVM/Clang maintainers already take care of this.
Due to the above, CastXML supports recent versions
of Visual Studio, while GCC-XML does not support
VS 2010 or later.
4. CastXML can parse in some language modes besides C++98,
though since the output format currently matches GCC-XML,
only C++98-compatible interface structures appear in the
For discussion of CastXML please join the mailing list for
that project rather than posting on this gccxml list. The
CastXML mailing list is here:
 If anyone is interested in continuing to maintain gccxml
please contact me off-list to volunteer.
 The output format is intended to be close to gccxml's
format to make porting clients easy. There may be some
differences where output constructs depend on internal
compiler implementation details.
