vhpi build on clang arm64 macOS

[metebalci]

VHPI library cannot be built like it is described in man page (cc -shared -fPIC my_plugin.c -o my_plugin.so) on macOS using clang because any vhpi_ function causes undefined symbol errors. -Wl,-undefined,dynamic_lookup can be used but then all such errors are disabled and it is not convenient to disable this for each symbol. Would it not be useful to build a vhpi library when building nvc ? (similar to libghdlvpi built with ghdl)

You might want to try creating a bundle instead (e.g. see here https://stackoverflow.com/a/50183179). Something like:

clang -o my_plugin.so my_plugin.c -bundle -bundle_loader $(which nvc)

Windows has the same issue and there it's possible to link against the executable which exports the VHPI symbols without an intermediate library.
