Hi Keith -
Thanks for sharing the scripts. It definitely helps.

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.
