Question

我设法在openCV网站上运行示例，在eclipse中显示图像（http://docs.opencv.org/doc/tutorials/introduction/linux_eclipse/linux_eclipse.html）

我有另一个项目，其中我从mat文件中读取了一些矩阵，当我尝试合并这两个时，为了显示从mat文件中读取的图像，显示了以下错误：

这个错误甚至在opencv示例中显示，当我只添加-Wl，-rpath，/ usr / local / MATLAB / R2014b / bin / glnxa64时，不向源文件添加任何代码。没有旗帜，一切正常。

如何在这个opencv项目中包含matlab代码？

Answer 1

这个话题很老但我遇到了同样的问题，我修好了。

我尝试重新安装OpenCV，最后我发现ccmake

BUILD_TIFF | OFF

是安装OpenCV时的defaut参数。

所以我把它打开并重新安装OpenCV，它的工作原理。

仅在使用-Wl，-rpath，/ usr / local / MATLAB / R2014b / bin / glnxa64添加Matkab代码后才链接错误OpenCV
