  • Added shared-library field in fpm.toml which tells fpm whether to generate the shared library or not.
  • Added the logic to generate shared library.

Maybe this could use the archive we are already generating. A wildcard for all object files would not be acceptable in any case, let's be explicit about them.

Is there a direct way to get the access to build directory of FPM_TARGET_OBJECT ? @awvwgk

Would this command work for all compilers in the fpm suite, or there are compiler specific flags that should be used?

Also the .so output looks a bit odd to me: isn't a dynamic library supposed to be named .dll on Windows and .dylib on macOS?

Thanks for the review @perazz . .so works well with Unix based operating systems so it works for macOS as well.

But, for windows still need to make .dll format for it.

This thread on SO seems to indicate .dylib as the canonical "dynamic library", whereas ".so" is used for plugins. In practice the formats are (mostly) the same. The Mac Dynamic Library Usage Guidelines refer to .dylib in many places, but don't mention .so.

So I think .dylib and the flag -dynamiclib instead of -shared would be the preferred option for MacOS.
