Unable to generate xml with Boost on Windows and MSVC about castxml

[bradking]

I think the problem is that CastXML is a Clang parser but is simulating MSVC's preprocessor, so Boost's preprocessor library is using MSVC-specific code instead of its implementation for Clang. In the past with gccxml this worked because the Boost headers gained explicit knowledge of gccxml here.

Something similar may be needed for CastXML, but currently CastXML does not define any macro to identify itself.

CastXML does not define any macro to identify itself.

Commit d2ef49b adds predefined macros that identify both CastXML and the internal Clang version against which it was built. This provides enough information for the Boost preprocessor library to adapt (via boost/config/select_compiler_config.hpp) to the CastXML preprocessor behavior.

Actually modifying Boost with this information is beyond the scope of CastXML development.

@bradking thank you!
I will send an issue to Boost to support CastXML preprocessor behavior.

Hi,

I'm currently facing these issues. Boost doesn't have CastXML support. Is there any workaround that I could use?

I use: Window 10, Boost 1.70, msvc2022, CastXML 0.4.3
