[dpdk-dev] building shared library

[Newman Poborsky]

Hi,

I want to build one .so file with my app (it contains API that I want to
call through JNI) and all DPDK libs that I use in my app.

As I've already mentioned, when I build and start my dpdk app as a
standalone application, I can see that before main() is called, there is a
call to 'rte_eal_driver_register()' function for every driver. When I build
.so file, this does not happen and no driver is registered so everyting
after rte_eal_init() fails.


BR,
Newman
