Adham... I don't think we debugged using clang compiled code for Hello world - mainly because it was only a "helloworld" application and we didn't quite need any debugging!:-)
I found this link: http://blog.llvm.org/2017/08/llvm-on-windows-now-supports-pdb-debug.html ...which says to use the following: Here are two simple ways to test out this new functionality: 1. Have clang-cl invoke lld automatically clang-cl -fuse-ld=lld -Z7 -MTd hello.cpp 1. Invoke clang-cl and lld separately. clang-cl -c -Z7 -MTd -o hello.obj hello.cpp lld-link -debug hello.obj Can you try it with just the -Z7 option? I'm also adding some persons from Microsoft to this thread, hoping they can help... +Harini +Omar +Jeffrey ranjit m.

But when running the helloworld with WinDbg, we can see only function names, we can't see code neither variables, we get the following error: "Private symbols (symbols.pri) are required for locals." We tried to append some flags like -Z7 and -gcodeview, but the compiler ignores them. Do you have any idea what we miss here ? What is the debug mechanism is being used in Windows ? Thanks
