error parsing std libraries

[xlab]

Just for note: generates fine with default Apple LLVM, I do not use --ccincl (see Makefile)

$ clang -v

@terinjokes could you please post snippets or the whole file somewhere? Also please try -ccdefs and -ccincl flags (in different combinations):

c-for-go vorbis.yml
c-for-go --ccincl vorbis.yml
c-for-go --ccdefs vorbis.yml
c-for-go --ccincl --ccdefs vorbis.yml

stddef.h

stddef.h hasn't changed in a number of years, and my version is a byte-for-byte match with master.

[xlab]

include file not found: stddef.h. Search paths:
        /usr/include

On my machine, that file is available at:

/usr/include/stddef.h

Hey, just wanted to point out that on my system stddef.h is not located in /usr/include either. It's dependent on the compiler in question, so for me it's located under /usr/lib/gcc/x86_64-pc-linux-gnu//include, so I had to manually add that to the include paths. Apple's Clang probably assumes that it is the only compiler installed on the system and places its stddef.h in /usr/include.

Hello! Trying to make a change to the vulkan-go manifest and getting this issue when I try to rebuild. I'm using Mojave 10.14.2. Clang gives me:

[Noofbiz]

The issue seems to be coming from the __has_feature(modules) macro for Clang. Is your stddef.h the Clang or GCC version?

ETA: Mine seems to be a copy of the one linked above. With the copyright (c) 2008 Eli Friedman header.

[RobinWragg]

I have exactly the same problem as @Noofbiz on Mojave 10.14.6, and I don't have /usr/include/stddef.h.

[xlab]

@RobinWragg I believe nobody has now, Catalina nuked /usr/include and there was some investigation in progress how to parse XCode internal includes that may contain weird macros:
#84

You may try something like

PARSER: 
  IncludePaths: [
    "/usr/include",
    "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include"
  ]

[RobinWragg]

@xlab thanks for the suggestion. After I added the full include path, I get the same errors as @terinjokes at the top of this thread, i.e. issues with parsing stddef.h.

[audiolion]

@xlab I am also getting similar errors as stated above after including /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include
