Unable to build rosidl_generarator_py package.

[goxul]

Hi,

I am using a Jetson Xavier NX board. Here's the relevant info:

NVIDIA Jetson Xavier NX (Developer Kit Version)
L4T 32.6.1 [ JetPack 4.6 ]
Ubuntu 18.04.5 LTS
Kernel Version: 4.9.253-tegra
CUDA NOT_INSTALLED
CUDA Architecture: 7.2
OpenCV version: 4.1.1
OpenCV Cuda: NO
CUDNN: NOT_INSTALLED
TensorRT: NOT_INSTALLED
Vision Works: NOT_INSTALLED
VPI: NOT_INSTALLED
Vulcan: 1.2.70

When I run the script, I get the following error:

--- stderr: rosidl_generator_py
Illegal instruction (core dumped)
make[2]: *** [rosidl_generator_py/rosidl_generator_py/_rosidl_generator_py_s.ep.rosidl_typesupport_fastrtps_c.c] Error 132
make[1]: *** [rosidl_generator_py_custom__py/CMakeFiles/rosidl_generator_py_custom__py.dir/all] Error 2
make: *** [all] Error 2

---

Failed <<< rosidl_generator_py [3.82s, exited with code 2]

Summary: 111 packages finished [1min 8s]
1 package failed: rosidl_generator_py
1 package had stderr output: rosidl_generator_py
88 packages not processed

I've gotten this error when I am building from source as well. Any idea how to fix it?
