我正在尝试以将C函数(作为字符串)发送到tcc编译器(libtcc.dll)的方式集成Visual C++ 2012和TCC。我已经添加了libtcc.h头文件,但是由于没有相应的.lib文件,我不确定如何添加libtcc.dll。我正在TCC发行版中使用libtcc_test.c文件作为Win32 main()函数。
这是我的主要内容:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#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 <= 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 && !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) < 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;
}
当我尝试运行它时,在Visual Studio 2012中出现以下错误:
error C3861: 'exit': identifier not found
error C3861: 'memcmp': identifier not found
error C2440: '=' : cannot convert from 'void *' to 'int (__cdecl *)(int)'
有人对此有解决方案吗?
谢谢!

我认为最简单的方法是制作一个.lib文件,然后将其用于链接。请参阅http://msdn.microsoft.com/en-us/library/0b9xe492.aspx上的MSDN页面,以了解如何从.def文件创建.lib文件。之后,您可以使用常规方法指定要链接的.lib。
