[llvm-dev] Ld64.lld cannot find Foundation framework

[Edmund Furse via llvm-dev]

Dear LLVM community I need some help please.

I want to use LLVM's clang and lld within a MacOSX sandboxed app.  This is because sandboxing does not allow calls to /usr/bin/clang.
The clang binary works fine to compile a file, but ld64.lld comes up with the error "cannot find framework".
However similar arguments using /usr/bin/ld instead of ld64.lld works fine.

Here are the details:

Here is the call using /usr/bin/ld:

/usr/bin/ld HelloObjC.o -o HelloObjC  -v -sdk_version 10.14.0 -macosx_version_min 10.14.0 -demangle -lto_library /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libLTO.dylib -dynamic -arch x86_64 -framework Foundation -framework Cocoa -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk -lSystem /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/10.0.1/lib/darwin/libclang_rt.osx.a -F/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk

This works correctly.

Here is the call using ld64.lld:

/Users/edmundfurse/Documents/NewClang/NewClangM21b/NewClangM21/Tools/bin/ld64.lld HelloObjC.o -o HelloObjC  -v -sdk_version 10.14.0 -macosx_version_min 10.14.0 -demangle -lto_library /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/libLTO.dylib -dynamic -arch x86_64 -framework Foundation -framework Cocoa -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk -L/usr/local/lib -lSystem /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/clang/10.0.1/lib/darwin/libclang_rt.osx.a -F/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk

gives the error message:

Library search paths:
    /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib
Framework search paths:
    /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
    /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/System/Library/Frameworks
ld64.lld: error: Unable to find framework for -framework Foundation

Any suggestions welcome.
