miniz.c在VS中获取"已定义"错误

Question

将miniz.c添加到项目并包含它之后:

#include "miniz.c"

int main(){
    return 0;
}

链接器会发出大量"已定义"的错误.

Answer 1

永远不要包含源文件!他们不打算这样做.

头文件中的单独声明.h和文件中的定义.c.

在任何需要引用声明的地方包含头文件.

至于你的具体情况,你应该包括miniz.c如下

#define MINIZ_HEADER_FILE_ONLY
#include "miniz.c"

int main(){
    return 0;
}

这在miniz.c文件本身中记录(在第928行)

// ------------------- End of Header: Implementation follows. 
// (If you only want the header, define MINIZ_HEADER_FILE_ONLY.)
