How to cross debug Kratos under Windows
The presented development environment allows to cross debug Kratos (Phyton and C++). In addition, it is possible to easily switch between the Debug and Release configuration. Moreover some hints how to bypass common errors in setting up Kratos under Windows (see also Windows Install) are provided.
- Visual Studio 2015 (see Windows Install) for debugging C++
- Visual Code (https://code.visualstudio.com/) for debugging Python
For debugging Kratos, Visual Code requires a Pyhton extension. The following screenshot shows some useful extensions.
To allow for fast switching between the Debug and Release configuration it is strongly recommended to use two different build folders (e.g. build_release and build_debug) with two different configuration files (see -DCMAKE_BUILD_TYPE=Debug or Release in configure.bat).
- Make sure you have compiled the boost library in the Release and Debug modus
- Make sure the following environment variables are set properly PYTHONPATH=[e.g. C:\Kratos_install], LD_LIBRARY_PATH=[e.g. C:\Kratos_install\libs] and add e.g. C:\Kratos_install and C:\Kratos_install\libs to the variable PATH
- Make sure you have copied the necessary Release AND Debug .dll files into the Kratos installation folder (see Post Compilation in Windows Install)
The first step is to perform one debugging step (Python) in Visual Code (Hint: use "stopOnEntry": true in the launch.json file). This creates a Python process.
Once the first debugging step in Visual Code is done, one can attach the Visual Studio Debugger (C++) to the before created Python process.
Done! Now you can cross debug Kratos (Python and C++) under Windows.
- For switching between Debug and Release you need to open the two different KratosMultiphysics.sln files created by CMake in the corresponding build folders e.g. build_release and build_debug
Have fun by cross debugging Kratos under WINDOWS ;-)
