hi, This mailing list is the support according to the contact page: https://www.graphics.rwth-aachen.de/software/openflipper/contact/ although, I can't access the archive: https://mailman.rwth-aachen.de/mailman/listinfo/openflipper There's also a bug tracker: https://graphics.rwth-aachen.de:9000/OpenFlipper-Free/OpenFlipper-Free/-/iss... but I don't see an option to sign up. -- I'm trying to build openflipper with vs2019, using vs2017 toolset. I'm using cmake 3.18. I'm successfully creating .sln through cmake with: mkdir build cd build %CMAKE_EXEC% ^ -DEIGEN3_INCLUDE_DIR:path="c:/prj-external-libs/eigen-eigen" ^ -DQT5_INSTALL_PATH:path="c:/Qt/online2/5.13.2/msvc2017_64/" ^ -Wno-dev -G"Visual Studio 16" -A"x64" -T v141 .. When I build the project, uic isn't called and it can't find auto-generated headers such as ui_pythonWidget.h. These headers aren't generated. I'm not too familiar with qt. I can see that cmake creates a pre-build event that runs its autogen on, e.g., c:\prj-external-libs\OpenFlipper\build\OpenFlipper\CoreApp\CMakeFiles\OpenFlipper_autogen.dir\AutogenInfo.json It's supposed to scan the source files for including ui_*.h, and call uic accordingly. Something fails here. As a sanity check, I was able to build successfully a cmake-qt test project: https://github.com/jasondegraw/Qt-CMake-HelloWorld Thanks, Zohar
