Hi everyone,
We have a new crypto PMD submitted on ML
(http://patches.dpdk.org/project/dpdk/cover/20221008083747.6559-1-zhangfei....@linaro.org/)
This PMD is dependent on an external library which needs to be cross
compiled for ARM on x86.
It mandatorily need “numactl” also cross-compiled and instead of
using pkg-config of libnuma, it need the library and headers to be
copied manually to aarch toolchain.
And if that is also done, it is not generating pkg-config which DPDK
can use to compile the PMD.
Thanks for the guidance
We are trying to provide pkgconfig file for uadk libs
https://github.com/Linaro/uadk/pull/513
And have fixed the x86 local build.
https://github.com/Linaro/uadk/pull/512
Under this git pull, I have verified building and installing dpdk on x86
with this diff to switch to pkg-config

One uncertainty is numa, "Requires: numa",
This requires numa.pc has to be installed, so numa only can be installed
from source code (make install).
While apt-get install libnuma-dev does not install numa.pc, so system
can not search numa.
So do we have to build numa from source code?
Thanks
