You probably need to call `jl_init(NULL)` at the beginning of the program.
If you have not done so yet, I would suggest to read the embedding
documentation:
http://docs.julialang.org/en/release-0.3/manual/embedding/
and start with the embedding example in the source:
https://github.com/JuliaLang/julia/blob/master/examples/embedding.c
