            Bug ID: 744
           Summary: [dpdk-19.11.9-rc3] make build failed on Fedora34 with
                    GCC11
           Product: DPDK
           Version: 19.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: yux.jiang@intel.com
  Target Milestone: ---

[DPDK version]:
e5f56f22a8 (HEAD, tag: v19.11.9-rc3, origin/19.11) version: 19.11.9-rc3

[OS version]:
Fedora 34 (Server Edition)/5.12.10-300.fc34.x86_64
gcc version 11.1.1 20210531 (Red Hat 11.1.1-3) (GCC)


[Test Setup]:
export RTE_TARGET=3Dx86_64-native-linuxapp-gcc
export RTE_SDK=3D`pwd`
rm -rf x86_64-native-linuxapp-gcc
rm -rf ./app/test/test_resource_c.res.o
rm -rf ./app/test/test_resource_tar.res.o
rm -rf ./app/test/test_pci_sysfs.res.o
make -j 20 install T=3Dx86_64-native-linuxapp-gcc  MAKE_PAUSE=3Dn

Should support to build 19.11.9 with GCC11 or not?
