Hi,
I'm trying to resurrect an open source C++ reflection tool
(https://github.com/Celtoys/clReflect ) against the latest clang. I've got
everything building and the tool produces some output, though I've yet to
analyse if the generated database is complete and correct.
I'm trying to build with Visual Studio 2017 on Windows 10.
I'm having a hard time getting the compiler settings correct to parse
Microsoft's Visual C headers, as most documentation is relative to the command
line.
First of all, what is the correct/official way to set
lang_options.MSCompatibilityVersion? clang::LangOptions::MSVC2017 by itself
doesn't seem to make a difference, one comment online seems to suggest a scale
factor, though it is odd that I can't find a macro or constant for this.
I am getting
"C:/Program Files (x86)/Windows
Kits/10/Include/10.0.17763.0/ucrt\stdio.h(378,9): warning : macro expansion
producing 'defined' has undefined behavior
2> #if _CRT_INTERNAL_NONSTDC_NAMES"
which is supposedly fixed by "-Wno-expansion-to-defined", though
"m_DiagnosticOptions.Warnings.push_back("no-expansion-to-defined");" doesn't
seem to make a difference. While I can obviously fix my own code not to use
undefined behaviour, I don't want to require a change to the standard C headers
that come with Windows.
And I'm getting
"2>E:/External/clReflect/src/clReflectTest/clcppcodegen.cpp(211,7): warning :
forward references to 'enum' types are a Microsoft extension
2> enum NoInit;"
I've got
" lang_options.MicrosoftExt = 1;
lang_options.MSVCCompat = 1;
lang_options.DeclSpecKeyword = 1;
"
are there any more options to enable Microsoft-specific extensions?
Cheers,
Jens
