【问题描述】：

我已经尝试使用

处的说明构建 opencv 一个多星期了

http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html 和 http://miloq.blogspot.com/2012/12/install-opencv-ubuntu-linux.html 但是每次我进入“制作”步骤时，都会出现错误：

该过程运行了一段时间，然后停止在 79% 并出现上述错误。我认为问题可能是因为我没有安装 OpenCL 库。我按照 www.amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/07/AMD_APP_SDK_Installation_Notes.pdf 所示安装了它，但仍然没有运气。我正在运行 ubuntu 12.04 和 OpenCV 2.4.9。 AMD APP SDK的安装版本为2.8.1.0。请帮忙。到这里我就束手无策了。

【解决方案1】：

我遇到了同样的问题，并通过在 release 文件夹中使用以下 cmake 命令编译 OpenCV 而不需要 GPU 功能的模块为我解决了这个问题：

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_OPENCL=OFF -D WITH_CUDA=OFF -D BUILD_opencv_gpu=OFF -D BUILD_opencv_nonfree=OFF -D BUILD_opencv_stitching=OFF -D BUILD_opencv_superres=OFF ..

随后会停用以下模块：gpu、nonfree、stitching、superres

【讨论】：

我很高兴，不幸的是，这不是一个通用的解决方案，但只要它适合你。这似乎是 Ubuntu 12.04 特有的问题。
