Bug 110735

As a temporary work around--link to code from non-standard directory to the 32-bit /usr/lib directory, for example:

if [[ $ARCH == *86 ]]; then
sudo find ${HOME}/lib32/ -name "libXvMC*" -type f -maxdepth 1 -exec bash -c 'ln -s "$0" /usr/lib/"${0##*/}"' {} \;
sudo find ${HOME}/lib32/ -name "libXvMC*" -type l -maxdepth 1 -exec bash -c 'ln -s "$0" /usr/lib/"${0##*/}"' {} \;
fi

Then delete links after compiling finishes:

sudo rm /usr/lib/libXvMC*

_____
Update: setting an rpath on 32-bit complied libXvMC* would still not let Meson find the libs.

I'm not at my computer right now (its a holiday here), but you might be
able to fix this by seeing -Dc_link_args="-L /path/with/xvmc"

I'm on mobile, please excuse autocorrect fail.

I can wait.

Setting "-Dc_link_args" in a config file results in:
meson: error: unrecognized arguments: ..

So I set it in a meson crossfile like:
[properties]
c_link_args = ['-L /home/a/lib32']

Results in 'XvMCW not found'.

I also tried setting a native file (https://mesonbuild.com/Native-environments.html) mesa32.ini like:

[paths]
libdir = '/home/a/lib32'
prefix = '/home/a'

Still not found.

Ah, sorry. The -D version is for the command line, in the cross file it
would be :
c_link_args = ['-L', '/path']

In a crossfile, setting like:

c_link_args = ['-L', '/home/a/lib']

terminates meson configuring earlier and results in a new error:

meson.build:1114:2: ERROR: C library 'dl' not found

Thanks for your time.

I started thinking about this over the weekend, and realized that all of this work-arounding a lack of a .pc file for libxvmcw is silly, we should just add a pkg-config file so this is less painful:
https://gitlab.freedesktop.org/xorg/lib/libxvmc/merge_requests/2

I recompiled both 32-bit and 64-bit libXvMC with the patch applied and mesa meson configure error remains.
