Thanks Yichao Yu,
Your macro works fine.
So in the next step I tried the following flag: "--compile=all" during
system image compilation.
My userimg.jl:
@Base.ccallable Int64 jl_foo(x::Int64) = (x+1)
with the following C code:
#include <julia.h>
#include <stdio.h>
#include <math.h>
#include <time.h>
int main(int argc, char *argv[])
{
jl_options.compile_enabled = JL_OPTIONS_COMPILE_OFF;
jl_options.startupfile = JL_OPTIONS_STARTUPFILE_OFF;
jl_init_with_image(NULL, "libmyimg_all.dll");
jl_function_t *func = jl_get_function(jl_main_module, "jl_foo");
jl_value_t* argument = jl_box_int64(2);
jl_value_t* ret = jl_call1(func, argument);
if (jl_is_int64(ret)) {
int64_t retInt64 = jl_unbox_int64(ret);
printf("jl_foo(2) in C: %d\n", retInt64);
}
system("PAUSE");
int ret = 0;
jl_atexit_hook(ret);
return ret;
}
I got this message:

jl_foo(2) in C: 3
Press any key to continue . . .
Execution of my function was successful, but I think I found bug in
--compile=all implementation:
code missing for ... sysimg may not have been built with --compile=all
What do you think???
Thanks.
