Boa tarde, I have compiled your code with `gcc RBC_C.c -Wall -o RBC_C -lc -lm` Without -lc and -lm your code will not link. Additionally you can get rid of the memset warnings by adding #include <string.h> I ran your code on a Linux machine with `./RBC_C` and got this: Output = 0.562731, Capital = 0.178198, Consumption = 0.384533 Iteration = 1, Sup Diff = 0.0527416 Iteration = 10, Sup Diff = 0.0313469 Iteration = 20, Sup Diff = 0.0187035 Iteration = 30, Sup Diff = 0.0111655 Iteration = 40, Sup Diff = 0.00666854 Iteration = 50, Sup Diff = 0.00398429 Iteration = 60, Sup Diff = 0.00238131 Iteration = 70, Sup Diff = 0.00142366 Iteration = 80, Sup Diff = 0.00085134 Iteration = 90, Sup Diff = 0.000509205 Iteration = 100, Sup Diff = 0.000304623 Iteration = 110, Sup Diff = 0.000182265 Iteration = 120, Sup Diff = 0.00010907 Iteration = 130, Sup Diff = 6.52764e-05 Iteration = 140, Sup Diff = 3.90711e-05 Iteration = 150, Sup Diff = 2.33881e-05 Iteration = 160, Sup Diff = 1.40086e-05 Iteration = 170, Sup Diff = 8.39132e-06 Iteration = 180, Sup Diff = 5.02647e-06 Iteration = 190, Sup Diff = 3.0109e-06 Iteration = 200, Sup Diff = 1.80355e-06 Iteration = 210, Sup Diff = 1.08034e-06 Iteration = 220, Sup Diff = 6.47132e-07 Iteration = 230, Sup Diff = 3.87636e-07 Iteration = 240, Sup Diff = 2.32197e-07 Iteration = 250, Sup Diff = 1.39087e-07 Iteration = 257, Sup Diff = 9.71604e-08 My check = 0.146549 Elapsed time is = 1.59662 ... This should work on Windows too. I suspect you don't know how the C build process works. I suggest you start by figuring out what the difference between compilation, linking, and execution is.
