missing .so file

Regarding the missing clang plugin, I guess it is not supported anymore, see #3372

Regarding the missing header you can make it work specifying the headers file shipped with casadi explicitly,
in case of python with something like:

from pathlib import Path
opts = {"compiler_flags": f"-I{Path(cas.__file__).parent / 'include/'}"}
f_imp = Importer('solver.c','shell',opts)

NB1: Also installing ipopt on your system will likely solve that, in that case you will have the header the compiler is looking for on system default paths.

NB2: If you are code-generating the call to ipopt nlpsol plugin you may also need:
opts = {"compiler_flags": f"-I{Path(cas.file).parent / 'include/'}"
"linker_flags": f"-L{Path(cas.file).parent} -lcasadi_nlpsol_ipopt"}

It seems the opts you provided in the code block have at least compiled the solver for me, will have to wait till the evening till I get around to testing to verify this is a fix on my system. Seems likely though.

Re: installing ipopt on my system. Pretty sure it is installed already, but in any case trying to make a package with minimal dependencies for ease of distribution, so trying to avoid manual installs to the extent possible.

Thanks for the help!
