Has anyone been able to compile opencv with clang-cl ? We are trying to switch over to using clang-cl instead of MSVC since MSVC in VS2017 dies trying to compile/optimize some of our internal code but clang-cl works well. However clang-cl fails building upstream opencv which we use for quick prototyping.
Traceback attached and also filed a bug here: https://bugs.llvm.org/show_bug.cgi?id=39007
Thanks
