Hi Surya, SSE3 instructions are not enabled by default. To enable, you can either tell gcc your CPU architecture (-march=<arch>) as suggested by Marc, or enable just the specific SSE version that's supported by your CPU (e.g., make TOOLCHAIN_CFLAGS="-msse4")
See http://gcc.gnu.org/onlinedocs/gcc/i386-and-x86_002d64-Options.html for a list of CPU architectures and instruction flags.

I faced the same problem sometime ago. best marc On 29/11/13 11:39, Surya Nimmagadda wrote: > Hi, > > I am a beginner with dpdk and trying to follow the instructions in > http://www.dpdk.org/doc/quick-start > > I am seeing the following error when doing make with 1.5.0r2 or > 1.5.1r1 > > == Build lib/librte_meter > == Build lib/librte_sched > CC rte_sched.o > In file included from /home/surya/dpdk/dpdk-1.5.1r1/lib/librte_sched/rte_bitmap.h:77:0, > from /home/surya/dpdk/dpdk-1.5.1r1/lib/librte_sched/rte_sched.c:47: > /usr/lib/gcc/x86_64-linux-gnu/4.6/include/tmmintrin.h:31:3: error: #error "SSSE3 instruction set not enabled" > make[3]: *** [rte_sched.o] Error 1 > make[2]: *** [librte_sched] Error 2 > make[1]: *** [lib] Error 2 > make: *** [all] Error 2 > > I am running this on a Ubuntu VM (12.04) with gcc version 4.6.3 > > It built fine on another vm where I have Ubuntun 13.10 with gcc > version 4.8.1 > > Should I upgrade to 4.8.1 here as well (it has become a long process with lot of road blocks) or is there any simple fix? > > The DPDK doc says I just need gcc versions 4.5.x or later. > > Thanks, > Surya >
