Zapcc not able to compile due to not finding stddef.h while Clang compiles fine. #39

I am getting an error that zapcc can't find stddef.h? I have no clue as to what could be happening. Clang compiles perfectly.

zapcc had not been updated for quite a while, maybe the include paths are not correct for gcc 9.2.

hamoid commented 4 years ago

@yrnkrn Will that change in the future? Is it easy to update those include paths?

yrnkrn commented 4 years ago

Yes, cherry picking just the relevant source lines for these include paths should be easy.

dimitre commented 4 years ago

I'm having issues here too, zapcc doesnt find the file I need which is 

xcrun clang -c -M -xc - <<<'# include <TargetConditionals.h>'
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/TargetConditionals.h

any tips of how to make this work without recompile zapcc ? something like symlinks or maybe make additional folders?

and here the different paths for clang & zapcc

Maybe add the missing includes using -I flag.
