On ARM L4T distro I have to run catkin_make multiple times to compile
On my x86 machine, this package compiles fine for me on ros melodic. But on ARM platform (L4T 32.4.4 for NVidia Jetson) it will only compile for me if I run catkin_make _more than once_.
I did notice there wasn't an add_dependencies so I added:
add_dependencies(curve_fitting ${catkin_EXPORTED_TARGETS})
After the declared executable target for curve_fitting.
Why would running catkin_make multiple times work? And why would this issue only creep up on an ARM architecture?
Here's the logs from my docker container that runs catkin_make multiple times, successfully compiling on the last one. What I'm noticing is there appears to be a race condition where catkin_make doesn't get around to generating cpp messages until the second time I run catkin_make. The first time only python/js/lisp messages are generated:
