I cannot load the JSBSim UnrealEngine/UEReferenceApp.uproject into UE5:
- a popup reports missing modules (this is expected, according to Step 4 in the instructions, and requires a rebuild)
- the rebuild fails (see log below), so UE5 prompts me to build the code in the IDE (VS Code), but it fails:
make: *** No rule to make target 'CrashReportClient-Linux-Shipping', needed by 'RequiredTools'. Stop.
JSBSim was originally built in a <path to JSBSim>/build directory and there are several Makefiles in there. When the IDE tries to rebuild the plugin, I think it is trying to use a new Makefile in the <path to JSBSim>/UnrealEngine directory. Is that correct?
How can I rebuild using the IDE? Do I need to create any files for the build to work (e.g. using something like UE5’s GenerateProjectFiles.sh?)
