Although you haven't provided a lot of information, I will assume that Tx & Rx are both building in the shared source directories. This prevents parallel builds because the object files will collide. If this is the case, I suggest building in different directories and using VPATH to teach Make how to find the sources. Alternatively, you can keep the same basic Make structure, but add a variable that causes build output to go to a different directory for Tx and Rx. thutt -- My serverless microservice runs in the blockchain. _______________________________________________ Help-make mailing list Help-make@gnu.org https://lists.gnu.org/mailman/listinfo/help-make
