[cfe-dev] Fail to analyze an .m File

[Alberto Lagos via cfe-dev]

Hi,

I'm bulding a libTooling utility to inspect some aspects (Preprocessor
directives mostly) of the iOS source file (Objective-C for now). But when i
run:

./tool IndexingViewController.m -- -fmodules -std=gnu99 -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.4.sdk


The following errors appear:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.4.sdk/usr/include/module.modulemap:118:11:

Error while processing ~/Desktop/tool/IndexingViewController.m.

It seems that is not finding the includes for iOS witch is weird since is
all there. Probably is using some other includes?. If i run the tool
without modules enable (-fmodules) i have only one error:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS12.4.sdk/System/Library/Frameworks/Foundation.framework/Headers/Foundation.h
stdarg.h was not found.

What i'm doing wrong?

Thanks
