Shouldn't have to specify julia path in jl_init.

[twadleigh]

As it stands, if a path is not passed to jl_init, the default logic in _julia_init is used. There, if jl_compileropts.julia_home and the JULIA_HOME environment variable are not set, it derives the julia path from that of the current executable. When embedding, though, that's likely not the right place.

jl_init should use analogous logic, but derive the default path from the executing julia shared library.

See also JuliaLang/IJulia.jl#206 and #7801.

@twadleigh I also run into similar problems when using the embedding stuff under windows and had the idea that #5045 could make this more robust.

[stevengj]

On MacOS and Linux, we can use dladdr to find the libjulia path. On Windows, maybe GetModuleFileName? (See also here.) Ah, I see that's precisely what you did in #5045.

Closing this. Most likely way out of date.
