c语言写的程序怎么样生成.dll文件?

dll制作步骤:

1.编写dll函数实现源代码hello.c

#include

int say_hello(char* name)

{

printf( "hello %s\n ", name)

return 1

}

2.编写dll函数输出定义文件hello.def.

LIBRARY hello

EXPORTS

say_hello @1

3.编译dll源码,生成dll,lib文件.

3.1 新建命令行窗口

3.2 设置PATH ?? INCLUDE ?? LIB 3个环境变量.

SET PATH=K:\vcnet\vc7\bin%PATH%

SET INCLUDE=K:\vcnet\vc7\include%INCLUDE%

SET LIB=K:\vsnet\Vc7\lib%LIB%

3.3 编译hello.c

cd K:\Source\dllsample (hello.c和hello.def所在目录)

cl /c hello.c

3.4 链接hello.obj,生成hello.dll,hello.lib两个文件.

link /def:hello.def /dll hello.obj

4.测试dll函数.

4.1 编写测试代码 test.c

extern int say_hello(char* name)

int main(int argc,char** argv)

{

say_hello( "robbie ")

return 0

}

4.2 编译测试代码test.c

cl /c test.c

4.3 链接test.obj和 hello.lib,生成可执行文件test.exe

link test.obj hello.lib

4.4 运行test.exe,屏幕输出:

hello robbie

至此,一个dll构造完毕.

dll制作步骤: 1.编写dll函数实现源代码hello.c #include int say_hello(char* name) { printf( "hello %s\n ", name)return 1} 2.编写dll函数输出定义文件hello.def. LIBRARY hello EXPORTS say_hello @1 3.编译dll源码,生成dll,lib文件. 3....
