Trying to install onevpl-cpu on 32-bit Slackware, of course svt-hevc fails and linking fails too ...

I wonder if it buildable in 64-bit environments?

https://github.com/oneapi-src/oneVPL-cpu/blob/master/INSTALL.md

so, after installing in /usr/local it need this

guest@slax:/dev/shm/libvpl-2022.2.5/build$ source /usr/local/etc/vpl/vars.sh

basically add environment variables ...

now vpl-inspect, system_analyzer and sample_decode works!

guest@slax:/dev/shm/libvpl-2022.2.5/build$ ./sample_decode -sw h264 -i stream.264 -o out.yuv CONFIGURE LOADER: required implementation: sw

stream.264 raw elementary h264 stream was created by ffmpeg:

ffmpeg -i ~/0005.avi -c:v libx264 stream.264

file stream.264

stream.264: JVT NAL sequence, H.264 video @ L 12

but ffmpeg (git commit 73b3344edd39468cb3f729d613949f52dbcba84e compiled with ./configure --enable-libvpl)

still reports
