C++ - QtCreator qmake run compiler 'cl'

When using Qt Creator with qmake for a C++ project, you might need to configure the compiler and build tools to use a specific compiler, such as Microsoft's cl.exe, which is part of the Visual Studio toolchain. Below are the steps to configure Qt Creator to use the cl compiler with qmake.

1. Install Visual Studio and Set Up the Environment

Ensure that you have Visual Studio installed, including the necessary C++ development tools. To use cl.exe, you need to have the Visual Studio Build Tools installed.

  1. Install Visual Studio: Download and install Visual Studio from the official website.
  2. Install C++ Development Tools: During installation, select the "Desktop development with C++" workload.

2. Configure Qt Creator to Use Visual Studio Compiler

  1. Open Qt Creator:

    Launch Qt Creator and go to Tools > Options.

  2. Set Up the Compiler:

    • Navigate to the Build & Run section.
    • Go to the Kits tab.
    • In the Compilers tab, click Add to add a new compiler.
    • Choose Microsoft Visual C++ (or a similar option depending on your version of Qt Creator).
    • Configure the compiler settings:
      • Compiler Path: Locate the cl.exe compiler. It is usually found in a directory like C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\<version>\bin\cl.exe (adjust for your version).
      • ABI: Make sure the ABI matches the Visual Studio version you are using.

  3. Set Up the Qt Kit:

    • Go to the Kits tab within Build & Run.
    • Create a new kit if necessary, or edit an existing one.
    • Set the Compiler to the one you configured in the previous step.
    • Configure other settings like the Qt version, Debugger, and CMake/Makefile if applicable.

  4. Configure the Build Environment:

    You may need to set up the environment variables for cl.exe by using the Visual Studio Developer Command Prompt, which sets up the necessary environment variables for cl.exe and other tools.

    You can create a custom cmd.exe batch file to set up the environment and then call Qt Creator from this batch file:

    @echo off call "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" x64 "C:\Path\To\QtCreator\QtCreator.exe"

  5. Test the Configuration:

    Open your project in Qt Creator and run qmake to ensure it detects the correct compiler. You can build your project to confirm that cl.exe is being used.

Example Configuration

Here's an example of what your configuration might look like:

  • Compiler Path: C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Tools\MSVC\<version>\bin\cl.exe
  • ABI: Visual Studio 2019
  • Qt Version: Your configured Qt version
  • Build Environment: Ensure Visual Studio environment variables are set

Troubleshooting

  • Environment Variables: If cl.exe is not found, ensure that the environment variables for Visual Studio are correctly set.
  • Error Messages: Check for any specific error messages in Qt Creator's build output and address them as needed.

By following these steps, you can configure Qt Creator to use the cl compiler for building your C++ projects.
