在树莓派上升级opencv

Question

我目前在我的rapsberry pi上安装了opencv 2.4.1，并且一直在寻找将其升级到最新稳定版本2.4.10的方法。 我需要重新安装还是可以升级？

Answer 1

您将必须下载源代码并进行编译：

wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.10/opencv-2.4.10.zip

文档中针对Linux的说明基本上是：

Create a temporary directory, which we denote as <cmake_binary_dir>, where you want to put the generated Makefiles, project files as well the object files and output binaries.
Enter the <cmake_binary_dir> and type
cmake [<some optional parameters>] <path to the OpenCV source directory>
For example
cd ~/opencv
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
Enter the created temporary directory (<cmake_binary_dir>) and proceed with:
make
sudo make install

对于ubuntu 14.04，有一个详尽的教程可能也很有用。
