c++ - 仅在使用 -Wl,-rpath,/usr/local/MATLAB/R2014b/bin/glnxa64 添加 Matkab 代码后出现链接错误 OpenCV

Question

我已成功运行 openCV 站点中的示例，并在 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 文件中读取一些矩阵，当我尝试合并两者时，以显示从 mat 文件中读取的图像，显​​示这些错误:

当我只添加 -Wl,-rpath,/usr/local/MATLAB/R2014b/bin/glnxa64 而不向源文件添加任何代码时，即使在 opencv 示例上也会显示此错误。没有标志，一切正常。

如何将 matlab 代码包含到这个 opencv 项目中？

Answer 1

这个主题很旧，但我遇到了同样的问题并修复了它。

我尝试重新安装 OpenCV，最后我发现 ccmake

BUILD_TIFF | OFF

是安装OpenCV时的默认参数。

所以我将其设置为 ON 并重新安装 OpenCV，它就可以工作了。
