title: TCC with Visual Studio 2012
body: <p>I am trying to integrate Visual C++ 2012 and TCC in such as way as to send in a C function (as a string) into the tcc compiler (libtcc.dll).   I have added the libtcc.h header file, though I am unsure how to add the libtcc.dll since there is no corresponding .lib file.  I am using the libtcc_test.c file in the TCC distribution as my Win32 main() function.  </p>
  
  <p>Here is my main:</p>
  
  <pre><code>#include &lt;stdlib.h&gt;
  #include &lt;stdio.h&gt;
  #include &lt;string.h&gt;
  #include "stdafx.h"
  #include "libtcc.h"
  
  int add(int a, int b)
  {
      return a + b;
  }
  
  char my_program[] =
  "int fib(int n)\n"
  "{\n"
  "    if (n &lt;= 2)\n"
  "        return 1;\n"
  "    else\n"
  "        return fib(n-1) + fib(n-2);\n"
  "}\n"
  "\n"
  "int foo(int n)\n"
  "{\n"
  "    printf(\"Hello World!\\n\");\n"
  "    printf(\"fib(%d) = %d\\n\", n, fib(n));\n"
  "    printf(\"add(%d, %d) = %d\\n\", n, 2 * n, add(n, 2 * n));\n"
  "    return 0;\n"
  "}\n";
  
  int main(int argc, char **argv)
  {
      TCCState *s;
      int (*func)(int);
  
      s = tcc_new();
      if (!s) {
          fprintf(stderr, "Could not create tcc state\n");
          exit(1);
      }
  
      /* if tcclib.h and libtcc1.a are not installed, where can we find them */
      if (argc == 2 &amp;&amp; !memcmp(argv[1], "lib_path=",9))
          tcc_set_lib_path(s, argv[1]+9);
  
      /* MUST BE CALLED before any compilation */
      tcc_set_output_type(s, TCC_OUTPUT_MEMORY);
  
      if (tcc_compile_string(s, my_program) == -1)
          return 1;
  
      /* as a test, we add a symbol that the compiled program can use.
          You may also open a dll with tcc_add_dll() and use symbols from that */
      tcc_add_symbol(s, "add", add);
  
      /* relocate the code */
      if (tcc_relocate(s, TCC_RELOCATE_AUTO) &lt; 0)
          return 1;
  
      /* get entry symbol */
      func = tcc_get_symbol(s, "foo");
      if (!func)
          return 1;
  
      /* run the code */
      func(32);
  
      /* delete the state */
      tcc_delete(s);
  
      return 0;
  }

  <p>When I attempt to run it, I get the following errors in Visual Studio 2012:</p>
  
  <pre><code>error C3861: 'exit': identifier not found
  error C3861: 'memcmp': identifier not found
  error C2440: '=' : cannot convert from 'void *' to 'int (__cdecl *)(int)'
  </code></pre>
  
  <p>Does anybody have a solution to this?</p>
  
  <p>Thanks!</p>
