Installation Guide

[gurmeherchawla]

Your installation guide instructs to build the LLVM sources using the makefile.
After running the makefile, what must be done?

[macmade]

If you have built Clang/LLVM from the supplied makefile in ClangKit/LLVM, then everything should be fine.
The makefile copies the new libraries to the location expected by the Xcode project.

So simply rebuild ClangKit from Xcode...

[gurmeherchawla]

And where can I view these libraries in the Xcode project? Linked frameworks and libraries?

[macmade]

They are set in the target's build settings (OTHER_LDFLAGS).

[gurmeherchawla]

Even though I've done that, I am still getting the following verbose message in the CKDiagnotic:
ignoring nonexistent directory "/Users/Gurmeher/Library/Developer/Xcode/DerivedData/ClangKit-ddxafeblyiqsqwagblctgyofkfet/Build/Products/Debug/ClangKit.framework/Versions/A/clang/3.7.0/include"

[gurmeherchawla]

Must there be a clang directory in the ClangKit Framework's root?

[macmade]

No, there's not... Clang include are not copied into the framework.
Looks like you modified the project to copy them, hence the error...

[gurmeherchawla]

The include directory is not being copied into the framework.
It seems that the CKTranslation is looking for include directory at the root folder of the framework, and cannot find the same.

[macmade]

I have no idea about what you are trying to achieve.

If you don't give me some context, I won't be able to help you...

• Are you experiencing a compile-time issue, or a runtime issue?
• Why are you rebuilding LLVM?
• How did you modified the project?
• ...

I cannot read your mind...

[gurmeherchawla]

• I have built the ClangKit(framework) target from Xcode.
• I have then run the ClangKitTest target.
• The C code compiles without any diagnostics.
• However, when the Objective-C Code compiles with the diagnostic: "'stdarg.h' file not found"
• On passing the "-v" flag in the CKTranslationUnit arguments, I am getting the message:
  ignoring nonexistent directory "/Users/Gurmeher/Library/Developer/Xcode/DerivedData/ClangKit-ddxafeblyiqsqwagblctgyofkfet/Build/Products/Debug/ClangKit.framework/Versions/A/clang/3.7.0/include"

[macmade]

Ok, so this is a runtime issue.
Basically, it means that ClangKit is working fine, if it gives you diagnostics.

Again, as mentioned in your previous issue, if <stdarg.h> is not found, it means your development environment is not correctly set-up.
And ClangKit warns you about this, as your compiler would do.

What version of macOS/Xcode are you using?

[gurmeherchawla]

The latest of both.
Also, I have tried running the app on various systems but with no success.

[macmade]

Ok, I'll see if I can update the example, so it's more clear.

The error you are getting just means you need to supply additional arguments to the translation unit, as you would do for a usual compiler.

[macmade]

OK, I've added an example in 6e2a2f5.
It gets the correct Clang include paths from the Xcode default toolchain, if available.

Depending on your Xcode version, ClangKit may report other diagnostics, because the LLVM libraries need to be updated for the latest macOS SDKs.
But as it seems you've updated them, this shouldn't be an issue.

I'll try to update them, but I'm on other things right now.
