Help cross compiling for ros2_java/Android
mclayton7 opened this issue · 2 comments
I'm looking into updating the https://github.com/ros2-java/ros2_java project to work with ROS2 Galactic, and the Android build is failing because it's trying to cross compile foonathan_memory and running the ARM64 cross compiled binary on x64. I've also read about using qemu as an emulator in these scenarios (#60)
I'm new to the ROS2 and ament ecosystem, so forgive me if this is a dumb question, but is there a way to pass arguments to ament such that qemu would get passed to the foonathan cmake scripts?

Error: Process completed with exit code 2.@mclayton7 You almost answered the question yourself. You've taken a look at #60. The important bit is that you should set CMAKE_CROSSCOMPILING_EMULATOR on your cmake toolchain file
This worked, thank-you @MiguelCompany!
