    <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; } </code></pre> <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>

    1. COtcc distributions are rarely updated. Most people on the mailing list would recommend that you get the latest code from the repository and go from there. See http://repo.or.cz/w/tinycc.git

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
