From: Tetsuya Mukawa <mukawa@igel.co.jp> When CONFIG_RTE_BUILD_SHARED_LIB is enabled, linking errors occured while compiling. It seems those errors are caused by wrong link order of some libraries. The patch fixes it like following. 1. librte_eal 2. librte_malloc 3. librte_mempool 4. librte_ring 5. librte_pmd_bond 6. librte_kvargs Signed-off-by: Tetsuya Mukawa <mukawa@igel.co.jp> --- mk/rte.app.mk | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-)

Please Tetsuya, could you describe how you test and what is the error message? Thanks

Anyway, I understand I shouldn't change link order, but should check why '--start-group/--end-group' doesn't work on my environment. I will describe more in the email for Thomas.

I have confirmed '--start-group/--end-groups' is specified while compiling, but I am still seeing the error.

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 > >> >
