This tells the compiler not to optimise for your machine. This switch can be used with debug or release mode. To enable, simply add: - -DCROSSCOMPILE=1 + -DNO_NATIVE_OPTIMIZATION=1 to your cmake command. -Note that real cross-compilation is hard at this moment, because an executable generated during the build process is required for later stages, so if your computer cannot run executables it generates the build will not work. - ### List of all build flags ### Cuberite's build process supports a large number of flags for customising the builds. Use these flags by adding `-DFlag_name=Value` to the cmake configuration command. For example to enable test generation using the `SELF_TEST` flag add: `-DSELF_TEST=ON` ###### BUILD_TOOLS -Adds the Cuberite tools to the build. At the moment only MCADefrag and ProtoProxy are added.
