What is an undefined reference/unresolved external symbol error and how do I fix it? 29个
我已经从SBIG网站下载了这个C代码,以便控制(拍照并保存)我从他们那里购买的相机(型号ST-401ME).我有一个需要调用它的Matlab程序,所以我试图用它的头和库编译(用Visual Studio)这个代码到一个可执行文件中.但是,当我尝试时,我得到上述错误.请注意,我已将包含库的文件添加到目录路径中.
输出的确切措辞是这样的：

我认为这与链接库有关.我从来没有在Visual Studio中学会过如何做到这一点,而且我在大学读取的课程是在5年前,所以我几乎没有记住任何东西.
由于代码的长度,我只会错误地发生错误的部分.如果您想要更多(如主要),请告诉我.
