            Bug ID: 333
           Summary: PCI devices not found when DPDK is linked as dynamic
                    libraries
           Product: DPDK
           Version: 19.08
          Hardware: All
                OS: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: Normal
         Component: core
          Assignee: dev at dpdk.org
          Reporter: stephen at networkplumber.org
  Target Milestone: ---

If DPDK is configured with RTE_SHARED_LIB=y then applications are not loading
the required PCI library and therefore devices are not found.

Example is that l3fwd works if linked statically but fails if built with shared
libraries.

# ./examples/l3fwd/build/l3fwd -n4 -l0-3 -w 02:00.0
EAL: Detected 8 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: failed to parse device "02:00.0"
EAL: Unable to parse device '02:00.0'
EAL: Error - exiting with code: 1
   Cause: Invalid EAL parameters  

The string 02:00.0 should have been parsed by PCI library and that will find
the device. but since library is not pulled in, the device is not found.
