We have been looking at this issue over the last couple of days. It seems to be an Ubuntu GCC related bug as it works on other distros. GCC is passing incorrectly the option '--as-needed' to LD resulting in wrong linking. > /usr/lib/gcc/x86_64-linux-gnu/4.8/collect2 --sysroot=/ --build-id > --eh-frame-hdr -m elf_x86_64 --hash-style=gnu --as-needed The '--as-needed' just at the end of the above line is incorrect and not matching a closing '--no-as-needed'. You may get away with it by adding 'EXTRA_LDFLAGS=--no-as-needed'. ie. $ make install T=x86_64-native-linuxapp-gcc EXTRA_LDFLAGS=--no-as-needed Sergio > -dynamic-linker /lib64/ld-linux-x86-64.so.2 -z relro -o testacl > /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/crt1.o > /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/crti.o > /usr/lib/gcc/x86_64-linux-gnu/4.8/crtbegin.o > -L/home/mukawa/tmp/dpdk/x86_64-native-linuxapp-gcc/lib > -L/home/mukawa/tmp/dpdk/x86_64-native-linuxapp-gcc/lib > -L/usr/lib/gcc/x86_64-linux-gnu/4.8 > -L/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu > -L/usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../lib > -L/lib/x86_64-linux-gnu -L/lib/../lib -L/usr/lib/x86_64-linux-gnu > -L/usr/lib/../lib -L/usr/lib/gcc/x86_64-linux-gnu/4.8/../../.. > -Map=testacl.map --cref main.o -export-dynamic --whole-archive > -lrte_distributor -lrte_kni -lrte_pipeline -lrte_table -lrte_port > -lrte_timer -lrte_hash -lrte_lpm -lrte_power -lrte_acl -lrte_meter > -lrte_sched -lm -lrt --start-group -lrte_kvargs -lrte_mbuf -lrte_ip_frag > -lethdev -lrte_malloc -lrte_mempool -lrte_ring -lrte_eal -lrte_cmdline > -lrte_cfgfile -lrte_pmd_bond -lrt -lm -lgcc_s -ldl --end-group > --no-whole-archive -lgcc --as-needed -lgcc_s --no-as-needed -lpthread > -lc -lgcc --as-needed -lgcc_s --no-as-needed > /usr/lib/gcc/x86_64-linux-gnu/4.8/crtend.o > /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../x86_64-linux-gnu/crtn.o > /home/mukawa/tmp/dpdk/x86_64-native-linuxapp-gcc/lib/librte_eal.so: > undefined reference to `rte_mempool_lookup' > /home/mukawa/tmp/dpdk/x86_64-native-linuxapp-gcc/lib/librte_eal.so: > undefined reference to `rte_mempool_create' > collect2: error: ld returned 1 exit status > > Regards, > Tetsuya > > > Sergio > > > > > >> ---------------------------------------------------------------------- > >> > >> I just enabled the following option, then compile DPDK. > >> CONFIG_RTE_BUILD_SHARED_LIB > >> Is this collect to compile PMDs as dynamic link libraries? > >> > >> With the option, all libraries include are compiled as dynamic link > >> library. > >> Does "--start-group/--end-group" options work with dynamic link libraries? > >> > >> Regards, > >> Tetsuya > >> >
