TinyC(TCC) 获得 LibTcc.dll 的简单方法

[lim2003]

长期从 CSDN 里 down 东西，获得支持， 可未曾为其添砖加瓦， 今天获知一个技巧性的东西，和大家共享。 ^_^

最近寻找可放在自己程序里的 C/C++ 脚本（所谓嵌入式脚本），CInt、Tcc 等等都试了个遍，最后看中这个两个。

特希望 Cint可用（虽然是日本人写的，丰田本田松下等等东东也为我们所用嘛，所以就不介意用人家的源代码啦），毕竟这东东是 C++ 的。 可不管怎么编译（MinGW中）， 获得的 LibCint.dll 怎么 LoadLibrary 都是失败，官网发布的LibCint.dll也是一样的问题， 让人灰心。

退而求其次， Tcc 这么小，挺可人，说明、例子看起来使用都很简单，可惜只是 C99 的。
可找老半天，就找不到 LibTcc.dll. 只好自己编译啦。

方法一：
根据 《基于Tiny C compiler的c脚本混合编程方法》，在 MinGW 中编译获得：
gcc -O2 -shared -Wall -Wl,--export-all-symbols -mpreferred-stack-boundary=2 -march=i386 -falign-functions=0 -fno-strict-aliasing -DTCC_TARGET_PE -DLIBTCC -o libtcc.dll tcc.c

好，该Dll 用 libtcc_test.c 测试通过。

方法二——本帖要说的简单方法：
灵机一动, TCC 号称最小编译器，但也是编译器嘛，所以直接用 TCC来编译自己获得：
tcc -shared -rdynamic -o libtcc.dll tcc.c

注意参数， 参数的说明，可参见 tcc.c 源程序本身。
哈哈，用 libtcc_test.c 测试，一样OK。
此法真是简单方便呀， 特别是对类似我这种长期在Win下编程的人。。。 说不定还能玩出其他花样。。。

据说今天也是光棍节，祝大家节日快乐！

cint性能比php还差很多....
tcc要好很多.但有很多BUG
其实C/C++的设计并不太适合用做脚本.选它们做脚本还不如用专门的脚本语言.像lua/javascript这些..
另外,如果真要用C/C++脚本.建议用ch.这玩意是商业软件.质量比较好.而且有免费版可以用.

用lua吧~~

[gamemagic]

很久前就关注过tcc

既然是编译器，肯定可以自编译了。

我不采用dll的方式，而是直接把源代码放进自己的工程里，随工程编译成exe

[gamemagic]

其实cint也没有问题啊，为什么一定要做成dll呢？我很不喜欢dll这个东西。

你可以编译成.lib静态库，给你的程序使用啊

和工程有关，所以习惯用dll。 ^_^

[gamemagic]

我是游戏开发的，所以可能不希望带有太多dll ^_^

[lim2003]

源代码直接放进工程，也挺好的。 ^_^
等会直接加把 CINT 的源代码加进工程试试。

用CINT 时，发布的文件量多不多？

[mnbqwe1]

dll2lib 可以转

[lim2003]

CINT总是嵌入调用不成功，老有R6034之类的运行时库错误。。。

毕竟用C来表达东西也比用 lua 等熟些， 所以

最后还是用 TCC，简单方便些。

谢谢各位！

Hi Lim2003, 谢谢你的分享。我在编译libtcc.dll的时候出现了错误，不知道为什么，可能是我的Mingw的安装或者配置有问题，问题如下：

请帮我看看什么地方出了问题，谢谢！

Hi Lim2003,请忽略上面的问题，上面仅仅是告警，DLL还是生成了，现在担心这个生成的DLL是否有问题，有待验证。谢谢！
