Using Clang configured with MSVC 2017 on Windows with QtCreator 4.3.1

  • Hi,

    I've been trying to build my Qt application using Clang.
    It worked fine (mostly) while I was using it alongside MSVC 2015's standard library (by simply using the auto-detected "LLVM 64bit based on MSVC2015" compiler), however, I would like to use some of the new C++17 headers that were shipped with MSVC 2017 only.

    QtCreator does detect my installation of LLVM/Clang 3.9.1, but it insists on using it configured based on MSVC 2015, and I can't find a way to switch it to be based on MSVC 2017.

    I have desperatly been trying to manually add some compiler configuration that would allow me to do such a thing, but it seems that I can not set up the build environment properly.

    For instance, if my understanding is correct, MSVC ships a script called vcvarsall.bat to set all the build environment variables necessary, but I can't see any option in the manual configuration for a Clang compiler (or a custom compiler for that matter) to call that script. Even though the auto-detected LLVM clearly knows this script and uses the MSVC 2015 version of it!


    I would like to avoid manually changing the build environment variables (mostly the include and lib paths for the standard library) for each of my projects, if at all possible.

    NB: I also have installed Qt 5.9 binaries built with MSVC2017, and it builds fine with MSVC.

    I am quite puzzled by this issue, so if anyone can point me in the right direction, it would be very much appreciated!
