            Bug ID: 61
           Summary: build fails when shared libs enabled and optimization
                    turned off
           Product: DPDK
           Version: 18.05
          Hardware: All
                OS: All
            Status: CONFIRMED
          Severity: normal
          Priority: Normal
         Component: core

          Reporter: erik.g.carrillo@intel.com
  Target Milestone: ---

Overview:

    Build fails with CONFIG_RTE_BUILD_SHARED_LIB=y and EXTRA_CFLAGS="-O0"

Steps to Reproduce:

        1. Generate config file with: "$ make config
T=x86_64-native-linuxapp-gcc O=x86_64-native-linuxapp-gcc"
        2. Set CONFIG_RTE_BUILD_SHARED_LIB=y in .config
        3. Run build with: "$ make V=1 EXTRA_CFLAGS='-O0'"

Actual Results:

    Build fails with following error:
