Hi Thomas,
I tried workaround 1, 2 and 3.
1. I still see some errors after disabling igb_uio(setting
CONFIG_RTE_EAL_IGB_UIO=n in x86_64-native-linuxapp-gcc/.config) in the same
kernel(2.6.32-621.el6.x86_64). Please see the attachment for detailed error
information.
2. I tried to build dpdk 2.2.0 on Rhel7.2 kernel(3.10.0-327.el7.x86_64) and
I didn’t see any errors.
3. I tried to compile older DPDKs(DPDK 1.7.1, DPDK 1.8.0 and DPDK 2.0.0) on
the same Rhel6.8 kernel(2.6.32-621.el6.x86_64). I am seeing the same errors
which I observed while building dpdk 2.2.0 when I try to compile older
DPDKs(DPDK 1.7.1, DPDK 1.8.0 and DPDK 2.0.0)
Thanks,
Murali

Yes there are a lot of workarounds (see the 4 proposals below).
igb_uio is an out-of-tree kernel module.
We are replacing it with upstream modules uio_pci_generic or vfio.
1/ Try to disable igb_uio in your config
(x86_64-native-linuxapp-gcc/.config):
CONFIG_RTE_EAL_IGB_UIO=n
2/ If you want igb_uio, you should upgrade your kernel 3/ If you want to
keep this kernel, you can try an older DPDK version 4/ If you want to keep
this kernel and this DPDK, you can try to fix
the issue and submit a patch to dev@dpdk.org.
