Hi all,

I did a static linking of libdpdk to my application and when I start the application EAL init fails.
Logs:
EAL: Detected 80 lcore(s)
EAL: Detected 2 NUMA nodes
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
EAL: Probing VFIO support...
EAL: VFIO support initialized
EAL: No legacy callbacks, legacy socket not created
MBUF: error setting mempool handler
EAL: Error - exiting with code: 1
  Cause: Cannot init packet mbuf pool Invalid argument

I installed DPDK-20.11 in my test server, using the following commands.
# meson build
#cd build
#ninja ; ninja install

I built my application Makefile taking l2fwd Makefile as an example, not sure what I am missing.
Looking out for suggestions.

Regards,
Prashanth

Update:
Had few issues with DPDK 20.11 in Centos-7.


  *   Installing  Mellanox libverbs somehow affects the cflags and ldflags for dpdk libdpdk.pc
  *   pkg-config from the installed target was also incorrect.

Manually updating libdpdk.pc to include the static libraries under -Wl,--whole-archive and -Wl,--no-whole-archive

Prashanth

This is a known issue with pkg-config 0.27.
See: https://doc.dpdk.org/guides/linux_gsg/sys_reqs.html?highlight=pkg%20config#building-dpdk-applications
