[dpdk-users] Compiling fails

[dpdk-users] Compiling fails

[Saint Michael]

I downloaded dpdk-20.02.tar.xz and run source usertools/dpdk-setup.sh but
the script fails to install with "Installation cannot run with T defined
and DESTDIR undefined"

I also need to build rtr_kni.ko, for my kernel 5.6.12-1.el7.elrepo.x86_64,
but the module that I need to compile, "rte_kni.ko" is not available, all I
see is
 find -name "rte_kni*"
./lib/librte_kni/rte_kni.h
./lib/librte_kni/rte_kni_version.map
./lib/librte_kni/rte_kni.c
./lib/librte_kni/rte_kni_fifo.h
./lib/librte_eal/linux/eal/include/rte_kni_common.h
./x86_64-native-linux-gcc/build/lib/librte_kni/rte_kni.o
./x86_64-native-linux-gcc/include/rte_kni.h
./x86_64-native-linux-gcc/include/rte_kni_common.h

kindly help me understand what am I doing wrong? My goal is to pin two
network interfaces to a single core each, to accelerate packet processing.

Please check the sec 3 of GSG.
Actually, what dpdk make procedure is looking for, DESTDIR for it to store
the lib and other stuff.

make install T=$RTE_TARGET DESTDIR=$DESTINATION_DIR

Here, RTE_TARGET is your target for example x86_64-native-linux-gcc
&
DESTINATION_DIR is any folder location where you want to store the libs.

Adding answer for your second question.
for ko for rte_kni, first you need to compile then you will be able to get
that.

I suggest you to use dpdk-setup.sh present in usertools folder.
