我正在尝试安装 OpenCV 2.2.0。我认为我在运行之前已经遵循了所有步骤make，但每当我输入时make，它都不起作用并且会出现 2 个错误。我不知道为什么会发生这种情况。请告诉我如何解决这个问题。
答案1
我正在尝试弄清楚您为什么使用 2.4 版本。错误通常都是次要的。例如，您可能没有安装次要依赖项。通常可以通过密切关注安装过程中的警告来检测这些错误。
我的建议是删除 cmake 创建的所有内容，然后重新运行 cmake。完成后，滚动到顶部并检查以确保已找到它所寻找的所有内容。如果它不是强依赖项，则在编译时，它会跳过它。
对于像您这样安装旧版本软件的情况，我会确保所有依赖项都比您尝试安装的旧版本更新。大多数新版本都与旧版本兼容，但它们无法测试所有内容。根据国防部的说法，100% 测试的有效性为 60-80%。
