Originally opened as https://github.com/drepl/drepl-old/issues/2

I'm unable to get drepl to compile. I'm getting the following error:

Undefined symbols for architecture x86_64:
  "_rt_loadLibrary", referenced from:
      _D4core7runtime7Runtime17__T11loadLibraryZ11loadLibraryFxAaZPv in drepl.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

That's with dmd. ldc thinks the problem is in engines.dmd.o (which does call loadLibrary).

Looks like linenoise isn't available and you get a terrible error message.

I don't think it's linenoise. I compiled it to a .so and was able to compile and run a test C program that used it. I'll check some more, but I've seen errors from not having linenoise and they don't look like this... The fact that loadLibrary is a D function also makes me think it's something else.

Do you compile with dub or manually? Maybe it helps to increase the verbosity of dub with dub --verbose?

Here's the full output from dub build --vverbose. I don't see anything more informative than the linker error from above. Are you compiling in a similar environment (OS X, dmd version, etc.)? (Thanks for the help!)

I wonder if the last comment on this thread is still operative: http://forum.dlang.org/post/[email protected]

"Does your code call Runtime.loadLibrary anywhere?

It looks like rt_loadLibrary is only implemented when on Windows or with version(Shared)."

(I'm not sure what version(Shared) is.)

Have you tried to remove that and see whether it compiles?

Yeah, that loadLibrary call is definitely the problem. I replaced that w/ void* lib; and got it to compile and run. The REPL takes inputs but doesn't seem to give output.

Running ./drepl
Welcome to D REPL.
D> import std.stdio;
D> writeln(10);
D> auto x = 42;
D> x
D>

I'm not 100% sure what expected behavior is, or what the workaround for loadLibrary is...

Nope it's not. Can you try

  1. a simple 1+1
  2. Just declarations (no importing)

There is no shared library support on OSX yet.

Maybe w/ ldc? Not sure what the problem there is.

There is no workaround, compiling and loading new code as shared libraries is how this REPL works.
