Please forgive me for taking so long to reply, I just came back from vacation yesterday.
Thank you it is working, well I have to do a manual configure to create a right Makefile but everything seems good. I can complie curl, json-c, …, copy them manually and make them run successfully in my MangOH board.
Your Makefile seems good, that might be what I need to create a packaging .update for each library/app and install it in Legato platform. I’ll keep you informed about my tests.
