Would using a unique directory per release not lead to clobbering up the lib directory unnecessarily? How about having a single "dpdk" or "dpdk-pmds" directory in lib, and having $MAJORVER as a subdir under that? E.g. dpdk/pmds-18.08/, dpdk/pmds-18.11/, or dpdk-pmds/18.08/ dpdk-pmds/18.11 [The former of the above would be my preference, since I don't like having hypenated names, and like having "dpdk" alone as a folder name :-)] /Bruce
