Trouble with calling include in julia C api. v0.7

I’m having some trouble including a file from the C api (via Java - but hopefully that doesn’t matter)

My code is:

#include <jni.h>
#include <stdio.h>
#include <julia.h>

void REPT() {
    if (jl_exception_occurred()) {
        jl_call2(
            jl_get_function(jl_base_module, "show"),
            jl_stderr_obj(),
            jl_exception_occurred());
        jl_printf(jl_stderr_stream(), "\n");
    } else {
        printf("OK\n");
    }
}

extern "C" JNIEXPORT jint JNICALL sayHello
        (JNIEnv * env, jobject self) {
    jl_init();
    REPT();
    printf("Printing include...\n");
    jl_eval_string("print(include)");
    REPT();
    jl_eval_string("include(\"code.jl\")");
    REPT();
    jl_atexit_hook(0);
}

and it is outputting :

OK
Printing include...
UndefVarError(:include)
UndefVarError(:include)

This suggests to me that the include function is not getting setup for some reason.

In contrast if I do a print(include) from the julia REPL I get Base.MainInclude.include as I’d expect.

What am I doing wrong?
