digitalmars.D.learn - Runtime.loadLibrary() on Linux

Is it possible?

I get a message "rt_loadLibrary() not supported on Posix" when I 
try. Is there something I'm doing wrong or is loading shared 
libraries not supported at all on Linux systems?

thanks.

No, not using "rt_loadLibrary". You can still use the good old C function "dlopen". I think "rt_loadLibrary" does some extra stuff that the corresponding Windows function for "dlopen" doesn't do for shared D libraries. -- /Jacob Carlborg

Ah, thank you. That set me on the right track.

It should be made to work on Linux. Interested in submitting a pull request? The function is in src/rt/dmain2.d.

Isn't it just a matter of dlopen on most (if not all) POSIX impls? -- - Alex
