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?
By the way.
When trying to use +Libs.Private: -lnuma,
I found Even remove building uadk, the dpdk fails if no numa.pc, though
apt-get insall libnuma-dev
/usr/bin/ld: lib/librte_eal.so.23.0: version node not found for symbol

ninja: build stopped: subcommand failed.
libnuma is a general requirement of DPDK.
numa.pc should be installed by the NUMA package.
Maybe a problem with your distribution.
It looks it is the numa source code issue.
Only if we do not install numa by source code,
apt-get install libnuma-dev always works.
But if install numa from source code once via make install,
apt-get seems not workable anymore, same on x86 or arm.
It only install symbol (libnuma.so), but no real library (libnuma.so.1.0.0)
$ sudo apt-get install libnuma-dev
$ numactl
numactl: error while loading shared libraries: libnuma.so.1: cannot open
shared object file: No such file or directory
$ ll /usr/lib/aarch64-linux-gnu/libnuma*

lrwxrwxrwx 1 root root 16 Sep 8 2018
/usr/lib/aarch64-linux-gnu/libnuma.so -> libnuma.so.1.0.0
More details, https://github.com/Linaro/uadk/issues/515
But never mind, will set numa as private, then both case can work, so
will ignore this issue first.
+Libs.Private: -lnuma
Thanks
