Hello Alexis,
Ecllipse IDE is not our product, so it is not in the scope of support, but according to above log, I can give you some advice.
From No.1 screenshot, It seems that Makefile file should be needed for your application, so "no rule to make target" was reminded.
For more detailed about Ecllipse on how to create a Makefile, see here:
Help - Eclipse Platform
Hope above information can help you!
Best Regards,
Weidong
