To: dev; +Cc: thomas.monjalon, ferruh.yigit, Jerin Jacob, stable
By introducing explicit -lrte_pmd_ixgbe link request in
testpmd Makefile,"-Wl,-lrte_pmd_ixgbe" provided twice, and linker
removes the duplication by keeping only first occurrence.
This moves "-Wl,-lrte_pmd_ixgbe" out of "-Wl,--whole-archive" flag
and makes symbol generation totally different than previous version
in case of static build.
This patch fixes the static build linking order by introducing
-lrte_pmd_ixgbe under the shared library config
(CONFIG_RTE_BUILD_SHARED_LIB).
Fixes: 425781ff5afe ("app/testpmd: add ixgbe VF management")

After second thought. -lrte_pmd_ixgbe coming first is problem for static compilation, but these libraries used only for dynamic compilation. And locations shouldn't matter with dynamic compilation. Can you please try converting to the following, that should work: +ifeq ($(CONFIG_RTE_BUILD_SHARED_LIB),y) +ifeq ($(CONFIG_RTE_LIBRTE_IXGBE_PMD),y) +LDLIBS += -lrte_pmd_ixgbe +endif +endif I will send a patch for this. > > No objection to initial proposal. > ^ permalink raw reply [flat|nested] 12+ messages in thread
