Does the build work without sed command, if it does then something is wrong with the sed command. In your case just edit the new config file and enable PCAP PMD if this style will work for you needs.

Do not know if this will help at all. I some times copy the config/deconfig_x86_64-native-linuxapp-gcc to config/deconfig_x86_64-mine-linuxapp-gcc then modify the new file to contain the changes you want the config file. This way you do not have to be concerned about how you do the make … config or as I do it this way.

cd dpdk
export RTE_SDK=`pwd`
export RTE_TARGET=x86_64-mine-linuxapp-gcc

make install T=$RTE_TARGET -j

You will get a warning at the end, but you can ignore it as you were not installing the results anyway. Here is a bash script I use being lazy.

function _rte() {
   if [ "$1" != "" ]; then
       export RTE_SDK=`pwd`
       export RTE_TARGET=`basename $1`
       echo "RTE_SDK: "$RTE_SDK " RTE_TARGET: "$RTE_TARGET
   else
       echo "Currently RTE_SDK: "$RTE_SDK " RTE_TARGET: "$RTE_TARGET
   fi
}

function _bld() {
   echo make -C ${RTE_SDK} install T=${RTE_TARGET} $@ -j
   make -C ${RTE_SDK} install T=${RTE_TARGET} $@ -j
}

function _dbld() {
   echo make -C ${RTE_SDK} install T=${RTE_TARGET} EXTRA_CFLAGS="-g -O0" $@ -j
   make -C ${RTE_SDK} install T=${RTE_TARGET} EXTRA_CFLAGS="-g -O0" $@ -j
}

alias rte=_rte $@
alias bld=_bld $@
alias dbld=_dbld $@


Then I just cd into the DPDK directory and type ‘rte x86_64-native-linuxapp-gcc’ then I can just do ‘bld’ to build DPDK and it does not matter which directory I am in when I do the build it will stay in the directory I executed ‘bld’. The dbld command is to build DPDK with EXTRA_CFLAGS=“-g -O0"

The rte command without args will print the current values and I normally cd to DPDK directory and do ‘rte x8<tab>’ to complete the command.

Anyway I hope that helps.
