It should also work to build applications with Makefile or any other kind of build system, but the trick is how to extract the build configuration/variables that were used for RTEMS. We are (slowly) moving toward an interface to get at those variables, with the rtems_waf module providing the state-of-the-art and best developed method. > On Wed, 17 Mar 2021 at 22:49, Gedare Bloom <ged...@rtems.org> wrote: > >> >> >> On Wed, Mar 17, 2021 at 2:23 PM Olga Syrbachova <syrba4ev...@gmail.com> >> wrote: >> >>> Thank you very much for your reply!
