So as it is, ACL autotest is broken when building static libs (non-combined). For combined libs we usually wrap libdpdk.a with --whole-archive, thus it is not an issue. Just thinking a bit more about the 'dlopen of drivers' case you mentioned before, shouldn't the driver have proper dependencies and therefore need shared DPDK libraries? What does happen if binary/app and driver are built against different library versions? Where does it say that we do support this use case? Sergio
