I tried the example [1] for embedding Julia in C, using the latest Julia-0.5 nightly, but have run into problems.
One trivial problem I had was that jl_atexit_hook(); seems to now require a return argument. That was easy to fix. However the C program given at [1] didn't link. It claims to not be able to find libjulia. Yet Julia is working fine on the system. I did a search to see if I could find libjulia and I have /usr/lib/x86_64-linux-gnu/julia/libjulia.so. But linking against this causes undefined symbol errors, and indeed nm seems to indicate that this library contains no symbols (it may be just a leftover from an old version of Julia I had installed or something). Is embedding currently supported with the nightlies? Do I need to install a different Ubuntu package to get libjulia? (I'm using Ubuntu 14.04). On a different, but related note, does anyone know what the current plans are for producing .o files or executables from Julia, rather than using it via the REPL? I know there was at one point some kind of compiler available. Has that been abandoned, or is it likely to resurface again in some form? I realise it's probably technically feasible. I'm really just asking whether it sits in the currently forseeable roadmap or not. Bill. [1] http://docs.julialang.org/en/latest/manual/embedding/
