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 -----Original Message----- From: Thomas Monjalon [mailto:[email protected]] Sent: Wednesday, March 23, 2016 7:31 PM To: Murali Krishna Cc: users at dpdk.org Subject: Re: [dpdk-users] dpdk 2.2.0 build failure on Rhel 6.8 Beta 1 Kernel Hi, 2016-03-23 19:04, Murali Krishna: > [root at Rhel68B1 dpdk-2.2.0]# cat /etc/redhat-release > > Red Hat Enterprise Linux Server release 6.8 Beta (Santiago) > > [root at Rhel68B1 dpdk-2.2.0]# uname -a > > Linux Rhel68B1 2.6.32-621.el6.x86_64 #1 SMP Wed Feb 24 00:07:06 EST > 2016 > x86_64 x86_64 x86_64 GNU/Linux [...] > /root/dpdk-2.2.0/x86_64-native-linuxapp-gcc/build/lib/librte_eal/linuxapp/igb_uio/igb_uio.c:213: > error: ?PCI_MSIX_ENTRY_CTRL_MASKBIT? undeclared (first use in this > function) [...] > Is there any workaround for this? 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 at dpdk.org. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...
