Dear USRP Users Mailing List Members,
I am following the guide called "Getting Started with DPDK and UHD - Ettus
Knowledge
Base<https://kb.ettus.com/Getting_Started_with_DPDK_and_UHD#Enable_hugepages>"
in order to run applications on USRP X440 with DPDK. As it is recommended, I
installed DPDK via the system-provided installer: sudo apt install dpdk
dpdk-dev . After the verification with dpdk-proc-info -v, the RTE Version is
shown as 'DPDK 21.11.6'
Then, I cloned the UHD v4.6.0.0 to my home directory in order to build UHD from
source. However, when I run the cmake ../ command the DPDK was listed under the
"UHD disabled components" and there were no errors. Nevertheless, there were
some messages related with DPDK:
CMake Warning (dev) at
/usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:477 (message):
'find_package()' specify a version range but the module DPDK does not
support this capability. Only the lower endpoint of the range will be
used.
Call Stack (most recent call first):
cmake/Modules/FindDPDK.cmake:86 (find_package_hangle_standard_args)
lib/CMakeLists.txt:63 (find_package)
This warning is for project developers. Use -Wno-dev to suppress it.
-- Could NOT find DPDK: Found unsuitable version ".", but required is at least
"18.11" (found /usr/include/dpdk;/usr/include/x86_64-linux-gnu/dpdk)
I checked uhd/host/lib/FindDPDK.cmake and edited the line 63 from
find_package(DPDK 18.11...21.11) to find_package(DPDK 21.11.6). Then the
warning messages disappeared in the output of cmake ../ and only the message
below remains:
-- Could NOT find DPDK: Found unsuitable version ".", but required is at least
"21.11.6" (found /usr/include/dpdk;/usr/include/x86_64-linux-gnu/dpdk)
I also tried to edit usr/include/dpdk/rte_version.h and
/usr/include/x86_64-linux-gnu/dpdk/rte_config.h in order to get around of the
version "." message. However, I failed.
What should I do to see the DPDK under "UHD enabled components" after writing
the build files with cmake ../ ?
Best Regards,
Altug KAYA
