CMake OpenCV 安装问题

这三个小时让我发疯了。我简单地想要安装 CMake，然后安装 OpenCV 3.1，但出现错误Unsupported protocol（请参见下文）。

我安装了 CMake 3.4.3。像这样：

wget https://cmake.org/files/v3.4/cmake-3.4.3.tar.gz
tar xf cmake-3.4.3.tar.gz
cd cmake-3.4.3
./configure
make
sudo make install

然后运行这个：

./bootstrap --prefix=/usr
make
sudo make install

当我在 OpenCV 的安装过程中运行此命令时出现错误：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

这是我收到的确切错误：

CMake Warning at 3rdparty/ippicv/downloader.cmake:56 (message):

因此显然存在哈希不匹配的情况。我猜这是 CMake 的问题（也许我的安装不正确？）。我该如何修复这个问题，安装 OpenCV 应该没那么难，对吧？

答案1

我找到了解决方案评论基本上我只需要手动下载文件ippicv_linux_20151201.tgz（从这里) 并将 zip 文件移动到正确的位置 ( /home/ao/opt/opencv/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e/)。

然后它就可以编译了:)

答案2

或者，你可以使用 SSL 支持重新编译 cmake，因为这最终是“哈希不匹配”的原因（状态：[1；“不支持的协议”]）

答案3

从 ：

再试一次：

 cmake \
 -DOPENCV_ICV_URL="http://downloads.sourceforge.net/project/opencvlibrary/3rdparty/ippicv"

答案4

如果您确定不想使用此第三方实用程序，您可以轻松禁用 IPP 选项。
