Ok, so first of all thanks a lot for all the help so far.
So, now I try to follow the instructions and I write the following three
lines of code inside C++:
jl_load("mymodule.jl");
jl_value_t * mod = jl_eval_string("mymodule");
jl_function_t * func =
jl_get_function(jl_new_module(mod),"myfunction");
(the jl file and the module itself have the same name in this case mymodule)
But I do receive the following 2 errors when Eclipse compiles:
1) error: invalid conversion from ‘void*’ to ‘jl_value_t* {aka
_jl_value_t*}’ [-fpermissive] (this is referring to jl_value_t * mod =
jl_eval_string("mymodule");)
2) error: cannot convert ‘jl_value_t* {aka _jl_value_t*}’ to ‘jl_sym_t*
{aka _jl_sym_t*}’ for argument ‘1’ to ‘jl_module_t*
jl_new_module(jl_sym_t*)’ (this referring to jl_function_t * func =
jl_get_function(jl_new_module(mod),"myfunction");)

You are totally right on this, I am just trying first to check if it is
doable to do some combinations between C++ in Eclipse and Julia (such as
using functions written in
Julia inside a C++ routine etc), because I am planning to connect a
large-scale C++ with Julia and before starting to studying Julia in full
detail and start writing proper
code was thinking to do some small tests in connectivity between the two.
But it turns out that I don't know some very basic things to finish this
task.
