@Silvia. In that case, NuttX build system is a set of plain makefiles. We have a makefile calling colcon with a cross-compilation toolchain. In this link: https://github.com/microROS/apps/tree/feature/microROS_stm32-e407/uros You can find the makefile and the related toolchain file. I think those are the files you may be interested. --- [Visit Topic](https://discourse.ros.org/t/ros2-cross-compilation/6834/11) or reply to this email to respond.
