Meson fails to detect the dependencies that are included
in PKG_CONFIG_PATH and built for ppc64le if binaries.pkgconfig
is not set in the ppc64le cross-file for Ubuntu.

This fixes the issue by setting binaries.pkgconfig to the
binary provided by the package 'pkg-config-powerpc64le-linux-gnu'.

Why not adding the same for ppc64le-power8-linux-gcc?

I didn't find any operating systems that distribute the powerpc64le cross-compiler with the binary names found in config/ppc/ppc64le-power8-linux-gcc.
Both Ubuntu and Fedora use the -gnu suffix. Fedora doesn't seem to have a pkg-config binary for powerpc64le though.

So how does it work on Fedora?

On Fedora, the pcc64 cross-compiler is provided by package 'gcc-powerpc64le-linux-gnu' with binary names /usr/bin/powerpc64le-linux-gnu-*, same as in Ubuntu.
The cross-file config/ppc/ppc64le-power8-linux-gcc doesn't work with Fedora since the binary names in the file don't have the -gnu suffix, so I'm not sure where this cross-file is being used.

Another issue I found is that when I set the correct binary names in config/ppc/ppc64le-power8-linux-gcc or use config/ppc/ppc64le-power8-linux-gcc-ubuntu, I get the following error on Fedora:
    config/ppc/meson.build:6:4: ERROR: Problem encountered: Only 64-bit compiles are supported for this platform type
It happens because cc.sizeof('void *') in https://git.dpdk.org/dpdk/tree/config/meson.build#n144 returns '-1'. I'm on Fedora 35.

Is anyone able to cross-build for ppc64le in Fedora?

I believe that's because the Fedora package doesn't provide stdio.h for ppc64le.

Hi Thinh,

I'm also able to cross-build for ppc64 on Ubuntu, but without setting binaries.pkgconfig, meson will skip some build targets, even if PKG_CONFIG_PATH points to their dependencies.
Have you tried on Fedora?

Hi Ali,
Sorry for the delay.
Cross-build failed - missing the stdio.h same as yours on Fedora 30 and 35.
checking gcc-powerpc64-linux-gnu.x86_64 and 
gcc-powerpc64le-linux-gnu.x86_64 packages, both do not ship stdio.h and 
other header files: pthread.h, inttypes.h, etc...

We are investing this issue.
Regards,
Thinh Tran

As Thinh points out, you can't cross-compile for ppc64le on Fedora with 
distro supplied packages.  Ran across this question about the issue 
relative to ARM on the Fedora Project website:

https://ask.fedoraproject.org/t/cross-compiling-to-arm/17864/12

And also confirmed internally with our toolchain developers that you'd 
need glibc support which isn't provided in the existing Fedora packages. 
  Consensus seems to be that Fedora cross-compile is for 
kernels/bootloaders only, though I'd love to hear from someone at Red 
Hat if I'm mistaken.

Ubuntu/Debian do support the functionality, so you could try those 
environments (as used by Github Actions for DPDK commits), use a third 
party toolchain such as those found on:

https://toolchains.bootlin.com/releases_powerpc64le-power8.html

Or you could use the IBM Advanced Toolchain for POWER:

What's the test environment that prompted this patch?  I'd like to try 
replicating before approving.

Not from me yet.

Just asked about the test environment so I can duplicate the issue.  My 
understanding is that Ubuntu cross-compiles for CI/CD are still working 
so I'd like to understand the test case the drives this need.

Trying to enable the mlx drivers when cross-building for ppc64le, I added the directory containing
the .pc files from an rdma-core (https://github.com/linux-rdma/rdma-core) ppc64le cross build, but Meson
didn't detect the dependencies without installing pkg-config-powerpc64le-linux-gnu and setting
binaries.pkgconfig as powerpc64le-linux-gnu-pkg-config.

I just tried to reproduce the issue with a cross build of numactl, but Meson will not
detect it, even with my change. Seems that PKG_CONFIG_PATH=:/path/to/numactl/build/lib/pkgconfig
gets ignored.

Hello David,

Do you still have any concerns about this change?
Do you have any similar use-cases that you can test? (i.e., check if pkg-config can detect a cross-built dependency for ppc64le).

By the way, we do a similar change for arm cross builds:
https://git.dpdk.org/dpdk/commit/config/arm/arm64_armv8_linux_gcc?id=f31d17807236094268ccd1bead5d740a10fec513

Thanks,
Ali
