When building with IWYU enabled I receive many errors regarding missing members and undeclared identifiers e.g: '/Library/Developer/CommandLineTools/usr/include/c++/v1/cstdint:153:8: error: no member named 'int8_t' in the global namespace using::int8_t;'
I built and installed IWYU from: https://include-what-you-use.org/downloads/ Using: -DIWYU_LLVM_ROOT_PATH=/usr/local/opt/llvm
Please could you suggest what I've got wrong to cause these errors? Failing that, how can I suppress these (false?) errors?
Programming with C++17. Using include-what-you-use 0.10 based on clang version 6.0.0. Compiling using clang 6.0.0. Builing using cmake 3.11.1. Mac OS High Sierra version 10.13.4.
Appears I was pointing to the wrong llvm path. As I was using the version of clang installed by homebrew the set path should have read:
-DIWYU_LLVM_ROOT_PATH=/usr/local/Cellar/llvm/6.0.0/
