To expand on this, the reason why meson requires a cross file for cross-compilation is because we allow build files to use both native and cross compilers within the same build. This is quite useful when you want to build a tool (or generator) as part of the project that you then use to build/generate other things that are used in the cross build. That workflow is really difficult or impossible in Autotools and CMake, but it's a surprisingly common use-case. Generating cross files is quite easy since they're INI files[1]. If you use the same toolchain for the entire build, you only need to generate it once. 1. https://docs.python.org/3/library/configparser.html Cheers, Nirbheek -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
