Checking prerequisites

https://doc.dpdk.org/guides/linux_gsg/sys_reqs.html

1. Check gcc version

   gcc --version
   

   version 11.4.0

2. Update and install build-essentials

   sudo apt-get update && sudo apt-get install build-essential
   

   sudo apt-get install libnuma-dev
   

3. The above step didn’t install pkgconf. Had to install it manually:

   sudo apt-get install pkgconf
   

4. Checked python version

   python --version
   

   version 3.10.12 present

5. Installed meson and ninja

   sudo apt-get install python3-pip
   

   pip install meson ninja
   

6. Installed pyelftools

   sudo apt-get install python3-pyelftools
   

7. Checked Kernel version and allocated hugepages

   uname -r

   returned 5.15.0-86-generic

   Checked the number of nodes:

   ls /sys/devices/system/node/ | grep node
   

   Allocated Hugepages:

   sudo su
   

   echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
   

   echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages
   

   then exit out of superuser mode

8. Cloned DPDK (ref: https://doc.dpdk.org/guides/linux_gsg/build_dpdk.html)

   git clone <https://github.com/DPDK/dpdk.git>
   

   cd dpdk
   

9. meson and ninja were not properly installed with pip. Installed them with

   sudo apt-get install meson ninja-build
   

10. Built dpdk

    meson setup -Dexamples=helloworld build
    

    cd build
    

    ninja
    

    sudo meson install
    

    sudo ldconfig
    

11. cd dpdk/build/examples and run

    sudo ./dpdk-helloworld -l 0-3 -n 4
