Hi Altug,
This issue might be related cmake version. Which version of cmake you are
using?
>From the uhd/host/cmake/Modules/FindDPDK.cmake file,
set(DPDK_VERSION "${DPDK_VERSION_MAJOR}.${DPDK_VERSION_MINOR}"
PARENT_SCOPE)
Somehow, your _MAJOR and _MINOR variables are not set. You should check
whether the rte_version.h file is reachable by printing DPDK_VERSION_STR
variable located at uhd/host/cmake/Modules/FindDPDK.cmake:24 . If it's
reachable, please check the REGEX can parse the expression set in lines 26
and 29.
Please let me know if you have any questions.
PS. Your email was flagged as spam, that's probably why nobody has seen it
until now. Fyi
A.
