I am trying to test out the DPDK sample applications in a CentOS 6.4 VM running under KVM, but I can't get DPDK to compile.

When trying to run 

make install T=x86_64-default-linuxapp-gcc -n

from DPDK-2.0.0, I get the following output:

[...]    
make S=lib/librte_eal/linuxapp -f /home/dpdk-1.6.0r2/lib/librte_eal/linuxapp/Makefile -C /home/dpdk-1.6.0r2/x86_64-default-linuxapp-gcc/build/lib/librte_eal/linuxapp all

I've installed all the required packages specified here:

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

and I've seen and attempted the solution here:

Intel DPDK Compilation Error

The issue appears for both DPDK2-0.0 and 1.6.0.

Also, just to make sure; running 

ls /lib/modules/2.6.32-358.el6.x86_64/build

returns output: 

/lib/modules/2.6.32-358.el6.x86_64/build

so the directory definitely exists..

I've managed to compile DPDK in a CentOS 6.6 KVM on the same host without issue, but this time around I keep getting this error.

Also it does need to be CentOS 6.4, sadly.

Update:

Added verbose output above ^

  • Can you enable verbose build output so as to see what command/etc. is actually failing at that point? – Etan Reisner Jul 07 '15 at 14:29
  • Thanks, I've edited the post to add some of the verbose output. (there wasn't anything about igb_uio before so I left that out) – Alex Hunter Jul 07 '15 at 14:39
  • Oh and yes, it's definitely failing, as when I try to insert the igb_uio module using the setup script, I get this message: "## ERROR: Target does not have the DPDK UIO Kernel Module. To fix, please try to rebuild target." – Alex Hunter Jul 07 '15 at 14:49

Just solved it:

I was using kernel version 2.6.32-358.el6.x86_64, and I had to update to version 2.6.32-504.23.4.el6.x86_64 to get rid of this error.

Additionally, I ran into another error after this which included the line 

previous definition of ‘skb_set_hash’ was here

This happened because of an issue with the DPDK version I was using (1.6) Trying 2.0 fixed this.

Then I got the following error when running any of the module-related options of the setup.sh script:

Traceback (most recent call last):
  File "tools/dpdk_nic_bind.py", line 536, in <module>
    main()
  File "tools/dpdk_nic_bind.py", line 532, in main
    get_nic_details()
  File "tools/dpdk_nic_bind.py", line 225, in get_nic_details
    dev_lines = check_output(["lspci", "-Dvmmn"]).splitlines()
  File "tools/dpdk_nic_bind.py", line 120, in check_output
    stderr=stderr).communicate()[0]
  File "/usr/lib64/python2.6/subprocess.py", line 642, in __init__
    errread, errwrite)
  File "/usr/lib64/python2.6/subprocess.py", line 1234, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

THIS error was because I didn't have pciutils installed and the script couldn't find lspci.

Hope this helps anyone else with the same issues.

When compiling the DPDK, you suppose to have dependency packages and besides that you must have kernel headers of the same kernel version. If you don't install kernel headers then "/lib/modules/your-kernel-version/build" folder is invalid otherwise it is valid.
