我正在尝试在 odroid 板上将 opencv 与 xubuntu 一起使用。
下载opencv2.4.8并执行以下命令
cmake -D CMAKE_BUILD_TYPE=REALEASE _D CMAKE_INSTALL_PREFIX=/usr/local/opencv
make
其次是 opencv linux安装
但是当我输入make.

如果我错过了一些库，请告诉我需要什么样的库以及我应该做什么。
我通过下载这些库解决了这个问题。
libopenal-dev
libxvidcore-dev
libx264-dev
libssh-dev
libmodplug-dev
libfaac-dev
libopenal-dev
libxvidcore-dev
libx264-dev
libssh-dev
libmodplug-dev
libfaac-dev
但出现此错误。
