Subject: [dpdk-dev] section mismatch warnings
Date: Mon, 6 Oct 2014 18:42:04 +0000 [thread overview]
Message-ID: <D058300A.10185%humichael@vmware.com> (raw)
Hi Everyone,
When we enable kernel config CONFIG_DEBUG_SECTION_MISMATCH=y and compile DPDK 1.7 with 3.14.17 kernel + gcc 4.8.2, we got lots of warnings like these.
Do we have plan to fix them? If so, please advise on which version. Thanks.
