在OPENCV安裝中出錯

Question

我試圖在Linux Mint中安裝opencv。 我在opencv文件夾中運行cmake命令。

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

但是我在release文件夾中運行make命令時遇到了一些與pango相關的錯誤：

//usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined reference to `pango_attr_font_features_new'
//usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined reference to `pango_renderer_set_alpha'

您需要使用$ mkvirtualenv cv -p python2重新啟動虛擬環境
