[dpdk-dev] problem with rte_hash

Hello all,

I am trying to do an example of using rte_hash, i am getting the following
linker problem:

/main.o   -lrte_eal -lpthread -lethdev -lrte_malloc -lrte_mbuf
-lrte_mempool -lrte_pmd_igb -lrte_pmd_ixgbe -lrte_ring -lrte_timer
-lrte_hash
/home/gal/dpdk/x86_64-default-linuxapp-gcc/lib/librte_hash.a(rte_hash.o):
In function `rte_hash_create':
rte_hash.c:(.text+0x6f8): undefined reference to `rte_cpu_get_flag_enabled'
collect2: ld returned 1 exit status

anyone familiar with that?

Thanks in advance!

Hi

Could this problem be a circular linker problem, try duplicating the libraries on the link line again and see if that fixes the problem. In GCC you also have the option --start-group and --end-group to force the linker to resolve  relink these libs until all of the dependences have been resolved.

In the mk/rte.app.mk makefile fragment is an example of these options.

I hope this helps.

Thank you, ++Keith

Hi,

Thanks for the help, i got it fixed (just moved the rte_hash library before
the rte_eal and it solved it)
