GCC 7.1 Compilation warning when compiling science and arm apps

[jessieramseyer]

I am making my way through the firmware training document. When I tried compiling the science and arm apps I receive these warnings.

Did the apps still compile? This could just be a warning that doesn't affect compilation

[jessieramseyer]

I rebooted my WSL terminal and the warnings have disappeared...? This doesn't match the expected output from the readme. Do you know if this is okay too?

[cindyli-13]

Could be because the app was already built? If you find under the folder cmake_build/SCIENCE_REV2_2021/develop/GCC_ARM/rover-apps/science_2021 a .bin and .elf and .elf.map and .hex file then that means you've already built the app

To echo what @cindyli-13 says, the ninja: no work to do indicates that the target has already been built.

Theres a clean target in the makefile that u can use to delete the built artifacts (ie. make clean)

Just fyi for github etiquette, always post terminal output using markdown code blocks instead of images so that its searchable.
