I am simply trying to run the first example attached in the embedding
documantation which is the following block of code:
#include <iostream>
#include <julia.h>
using namespace std;
int main() {
/* required: setup the julia context */
jl_init(NULL);
/* run julia commands */
jl_eval_string("print(sqrt(2.0))");
/* strongly recommended: notify julia that the
program is about to terminate. this allows
julia time to cleanup pending write requests
and run all finalizers
*/
jl_atexit_hook();
return 0;
}
And when I try to run the program in eclipse (after having linked the
library and defined the path of the header file) the above mentioned
error message appeas which says:
- System image file
"/home/kostas/workspace/juli/Debug/../lib/x86_64-linux-gnu/julia/sys.ji"
not found
