At least according to the "Mastering Cmake" boot, if your build process requires special tools built from project source in the native environment, that's a bit of a pain with CMake: https://cmake.org/cmake/help/book/mastering-cmake/chapter/Cross%20Compiling%20With%20CMake.html#running-executables-built-in-the-project I don't know whether newer version of CMake have a built-in concept of "this file must be built with a native compiler when doing a cross-build". ___ Sent via:Wireshark-dev mailing list Archives:https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe

Re: [Wireshark-dev] Issues with cross-compiling
The sad news is that the LEMON_C_COMPILER variable is a mini hack and I doubt it can be arm twisted to support your use case.
