I am trying to build Unreal engine 4.26 using clang (version 16.0.6). To ignore setting up the Unreal toolchain I add a PerforceBuild.txt under Build/. This indeed skips the downloading of the v17 clang from Epic but I end up with the following errors when trying to make
Creating makefile for CarlaUE4Editor (no existing makefile)
ERROR: Platform Linux is not a valid platform to build. Check that the SDK is installed properly.
make[1]: *** [Makefile:315: CarlaUE4Editor] Error 6
Some warnings are generated when generating the project files
WARNING: Exception while generating include data for UE4Editor: Platform Linux is not a valid platform to build. Check that the SDK is installed properly.
WARNING: Exception while generating include data for BenchmarkTool: Platform Linux is not a valid platform to build. Check that the SDK is installed properly.
[snipped]
Looking at other discussions it seems like it is complaining due to missing toolchain. But that is exactly what I am trying to avoid.
