[dpdk-users] igb_uio.ko is not generated via make/dpdk-setup.sh

[Hideyuki Yamashita]

Hello,

I have problem with dpdk-20.02 when compiling.

[1. What is the problem]
igb_uio.ko is not generated under build/kmod/ directory
thus I can not load/bind NIC with igb_uio.

[2.Which platform]
x86_64
Ubuntu 18.04.04 LTS

[3.Which build target]
x86_64-native-linux-gcc
x86_64-native-linuxapp-gcc

I used dpdk-20.02 tarball which can be downloaded via website.

[4.How I compiled source]
I tried the follwoing two ways but both failed to generate igb_uio
module.

4a
#sudo make install T=x86_64-native-linuxapp-gcc
#sudo make install T=x86_64-native-linux-gcc

4b
[for 19.11]
[38] x86_64-native-linuxapp-gcc
[45] Insert IGB UIO module
[50] Display current Ethernet/Baseband/Crypto device settings

All successful

[for 20.02]
[41] x86_64-native-linux-gcc
[45] Insert IGB UIO module

Option: 45

## ERROR: Target does not have the DPDK UIO Kernel Module.
       To fix, please try to rebuild target.

With regard to 19.11, using usertools/dpdk-setup.sh
perfectly worked. However something looks wrong with
20.02.
I've heard that building system is moving from "make"
to "meason". But following the official document
"make" is still supported. So for me it is very odd.


Thanks in advance!
