Hi
I am trying to build a legacy application with DPDK 19.11.14. It links
successfully but fails to parse the whitelisted pci device at runtime:
EAL parameters: phy_app --proc-type=primary --file-prefix wls -w 0000:43:00.1
EAL: Detected 64 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: failed to parse device "0000:43:00.1"
EAL: Unable to parse device '0000:43:00.1'
I think this suggests that the rte_bus_pci library is not loaded?
I suspect my linker command is incorrect. I am using CMake and I
detect the dpdk install using pkg-config. My linker directive is:
target_link_libraries(testApp PRIVATE
-Wl,--start-group
-lpthread
-lrt
-lhugetlbfs
-Wl,-lm
-Wl,-lnuma
-L${WLS_LIB_PATH}
-lwls
-L${_dpdk_lib_path}
-Wl,--whole-archive
${DPDK_STATIC_LDFLAGS} # DPDK libraries - static linking
-Wl,--no-whole-archive
-Wl,--end-group
)
I don't understand well the linker directives such as 'start-group'
and 'whole-archive'. Please could someone review the
target_link_libraries directive above and suggest what may be wrong?
I should mention that the DPDK 23.11 driver is running on the target
server, but I get a similar parse error if I build with DPDK 23.11.

I should have mentioned that the actual, expanded linker command is:
/usr/bin/cc -g <snip> -Wl,--start-group -lpthread -lrt -lhugetlbfs
