current ovs dpdk supports only dpdk-1.7.1.
so i was forced to use dpdk-1.7
I have seen a patch for similar error but it is for  dpdk-1.9.1 release
http://dpdk.org/dev/patchwork/patch/716/

How can I solve this error .

thanks,
srinivas.

hi,
Getting error while compiling dpdk on ubuntu10.04.


export RTE_SDK=$(pwd)
export RTE_TARGET="x86_64-ivshmem-linuxapp-gcc"

make CONFIG_RTE_BUILD_COMBINE_LIBS=y CONFIG_RTE_BUILD_SHARED_LIB=y
install
T="$RTE_TARGET"

Check to make sure you are linking in the math lib -lm you can add a V=1
to the command line and see the linker lines.
