And as soon I will include that Makefile it will do make all first. But I need only cflags and ldflags. To link pmds we did that hack: https://git.linaro.org/lng/odp-dpdk.git/commitdiff/9e41f167a8f44b74af6a1e1ffe00dc6d305ac8a4?hp=ac1789bfe9ceb6bbe04b6455f996680a20441813 Which mostly solved problem. But I would add sse and other cflags especially for inline functions to or link. Will take a look at examples/skeleton. Before I looked only to 1.7.1 and there is no such example. Looks like it appeared later. Thank you, Maxim.
