I did not follow to a tee all the other recommendations, but at times when I 
was using older an OS, I would try older libs and if I still could not get it 
to work, I would compile the lib myself. If the target hardware being used is 
too small in resources to compile, then I would create a VM with the same 
OS/Version with higher resources and then compile the libs. Then copy the libs 
to the target. Sometimes I had to use older versions of the lib sources to get 
it to work. Other times it was just finding whatever was hanging up the compile 
and fixing it, like finding required libs and proper versions. 

In any case, since you are using older versions, you can go to the custom build 
solution if needed. And just document the process. If this fall outside your 
liability model, then maybe not a great choice, but you can get it to work 
sometimes with these methods. 

Also, what did the AI's ask you to check. In cases like this I have seen them 
spin you around in many directions and never solve the issue. I have noticed 
that if there are not good proven solutions out there for your specific problem 
the AI's struggle and can drive you nuts with BS. But it is worth a shot anyway.

Good Luck!

I am stuck and hope someone in TriEmbed or EMP might know ..

I need to program a Linux process using the libgpiod library's C++ bindings. 
Trouble is all the examples in the source repo don't compile, and all other 
forum answers regurgitate the same examples. The same environment's rebuilt 
commandline utilities work fine.

Does anyone have any working example of reading some GPIO lines, and setting 
others?
