Opencv 打开Cv生成错误

我正在尝试安装opencv 3.0.0版。我以前安装过2.4版，没有错误，但是3.0版给我带来了很多麻烦。我的make命令总是出错。这是日志

知道哪里出了问题吗？

ctxMessageFunc/ctxStatusFunc/ctxMessageFunc的OpenCV声明与gphoto2中定义的参数列表不同

将代码修改为

friend void ctxErrorFunc(GPContext *, const char *, va_list args, void *);
friend void ctxStatusFunc(GPContext *, const char *, va_list args, void *);
friend void ctxMessageFunc(GPContext *, const char *, va_list args, void *);

并应用下面相同的更改

尽管如此，还有其他“函数缺失”问题，我只是将它们注释掉以通过编译阶段模块，最好获得兼容版本的gphoto2。

尽管如此，还有其他原因
