I normally do not get this error. I tested with other projects and it works fine but not for this one which includes several packages like Entities, Jobs, Mathematics and Burst. Is Burst not compatible with Linux at the moment? Why is it looking for gcc in a Windows environment? Se error below. Error building Player: BuildFailedException: Burst compiler (1.1.2) failed running stdout: Burst requires gcc/clang toolchains to be correctly installed in order to build a standalone player for Linux with X64_SSE4 Unable to find /usr/bin/clang or /usr/bin/gcc, is the gcc/clang toolchain installed?
