 An example of a micro-ROS application using PlatformIO is available [here](https://github.com/husarion/micro_ros_stm32_template).

+#### Known issues
+
+- `multiple definition of` Link errors on galactic:
+
+  Create a python script fix_linker.py on your directory and modify the linker flags manually:
+  ```
+  Import("env")
+  env["_LIBFLAGS"] =  ('-Wl,--start-group -Wl,--whole-archive '
+                      '${_stripixes(LIBLINKPREFIX, LIBS, LIBLINKSUFFIX, LIBPREFIXES, '
+                      'LIBSUFFIXES, __env__)} -Wl,--no-whole-archive -lstdc++ '
+                      '-lsupc++ -lm -lc -lgcc -lnosys -lmicroros -Wl,--end-group')
+  ```
+
+  Now add it to your `platformio.ini` like this: `extra_scripts = fix_linker.py` and delete the `-l libmicroros` line on `build_flags`.
