When dpdk is compiled as static libraries, it is not possible to load a plugin from an application. We get the following error: EAL: librte_pmd_xxxx.so: undefined symbol: per_lcore__rte_errno This happens because the dpdk symbols are not exported. Add them to the dynamic symbol table by using '-Wl,--export-dynamic'. This option was previously present when compiled with Makefiles, it was introduced in commitf9a08f6502("eal: add support for shared object drivers") Also add it to the pkg-config file. Fixes:16ade738fd("app/testpmd: build with meson") Fixes:89f0711f9d("examples: build some samples with meson") Cc: stable@dpdk.org Signed-off-by: Olivier Matz <olivier.matz@6wind.com> Reviewed-by: Bruce Richardson <bruce.richardson@intel.com>
