Hello, I would like to use PJSIP on a board wich conatain an ARM7 processor (STM32) with FreeRTOS OS. I have several questions : 1) Is it possible porting pjsip in this kind of architecture ? 2) If I understood correctly, I need GNU tools to make the library ? (do I need a Linux computer to make it ?) Thanks for you replies Best regards Sebastien
