问题描述
在将miniz.c添加到项目中并包含它之后：
After adding miniz.c to the project and including it:
#include "miniz.c"
int main(){
return 0;
}
链接器发出大量的已定义错误。 p>
The linker spits out a huge amount of "already defined" errors.

推荐答案
永远不要包含源文件！他们不打算这样做。
Never, ever include source files! They aren't intended to do so.
在头文件 .h 中单独声明并在 .c 文件。
Separate declarations in a header file .h and definitions in the .c file.
将头文件包含在需要引用声明的任何位置。
Include the header file anywhere you need to refer to the declarations.
对于你的特殊情况，你应该包括 miniz.c 如下
As for your particular case you should have included the miniz.c as follows
#define MINIZ_HEADER_FILE_ONLY
#include "miniz.c"
int main(){
return 0;
}
这在 miniz.c 文件本身（在第928行）
This is documented in the miniz.c file itself (at line 928)
// ------------------- End of Header: Implementation follows.
// (If you only want the header, define MINIZ_HEADER_FILE_ONLY.)
