Hi Kasim,
The files with extension *.a (static libraries) are source of the
problem. Put the needed libraries without static libraries in a separate
directory, let's say /usr/local/lib/x86_64-linux-gnu/pmds , and change
in the config to:
dpdk-driver=/usr/local/lib/x86_64-linux-gnu/pmds
UHD exiting due to too many library files in the dpdk-driverpath is a
very common problem when getting DPDK to work with UHD, what isn't
highlighted strongly enough in the Ettus's documentation.
Try to copy all librte*.so and librte*.so.* or only the ones needed by
you. I choose the second option and in my case I copied from
/usr/lib/x86_64-linux-gnu only:
librte_mempool_ring.so, librte_mempool_ring.so.20.0
librte_pdump.so, librte_pdump.so.20.0
librte_pmd_i40e.so, librte_pmd_i40e.so.20.0
librte_pmd_ixgbe.so, librte_pmd_ixgbe.so.20.0
librte_pmd_ring.so, librte_pmd_ring.so.20.0
Best Regards,
Piotr Krysik

Dear all,
I have a DPDK initiation problem
I installed DPDK19.11 with apt install and install UHD4.2 from source
and in the uhd.conf file I wrote the dpdk driver path as
dpdk-driver=/usr/lib/x86_64-linux-gnu
then I follow the instruction of Getting Started with DPDK and UHD to
run the uhd example with dpdk, then I get
EAL: /usr/lib/x86_64-linux-gnu/librte_pmd_enetc.a: invalid ELF header
EAL: FATAL: Cannot init plugins
Same error happens when I install DPDK18.11 and UHD4.0 manually from souce
.a is static library, so I suggest this is an install error of DPDK.
That's why I tried different installation, but both did not work
I would appreciate the help
Sincerely
Kasim
