[SOLVED] DPI and Questasim error

[brainiac_rus]

Hello!

I tryed to run DPI with Questasim. I saw topics about it but version of sim changed and some things could be changed too.

My C code:
#include <svdpi.h>
//#include <gmodel_tb_top.h>

int   factorial(int i)
{
   if(i <= 1)
   {
      return 1;
   }
   else
   {
      return i*factorial(i-1);
   }
}

My SV code

package user_math;
   import "DPI-C" function int factorial (input int i);
endpackage

module test;
   import user_math::*;

   initial begin
      
       $display("%d", factorial(1));
   end
  
  
endmodule

In console of questasim I do next thing:
vlib work
vlog gmodel_tb_top.sv gmodel.c
But the output:
vlog gmodel_tb_top.sv gmodel.c
# QuestaSim-64 vlog 10.2c Compiler 2013.07 Jul 19 2013
# -- Compiling package user_math

#
# Top level modules:

# ** Error: gmodel_tb_top.sv(14): Verilog Compiler exiting
# C:/questasim64_10.2c/win64/vlog failed.

Can you help me to find an error?

I get some thoughts about it.
I use win 7 x64 and may be for using C code questa needs c compiler, but in linux it is standard gcc, but in my windows it can't find it and can't do what i want. Is it true?

Yes, it is true!
I forgot install gcc compiler to my system, but do it and it starts to work!
Thank you for help!)
