Question

我正在尝试在Ubuntu 13.04（64位）上运行以下链接中给出的代码：

https://github.com/bensapp/Stretchable-Models-for-Motion-Parsing

我收到以下错误：

INVALID MEX FILE：'filepath / cps / utils / mex_opencv_boosting.mexa64'：filepath / cps / utils / mex_opencv_bosting.mexa64：undefined symbol：_ZN7CvBoostC1EPKc。

有人可以帮我修复此错误吗？

谢谢

当我运行命令lld mex_opencv_boosting.mexa64时，我得到以下输出。一切似乎都很好。

Answer 1

尝试以下

export LD_LIBRARY_PATH=filepath/cps/thirdparty/opencv/lib:$LD_LIBRARY_PATH

此后从终端运行MATLAB。你的代码应该运行。

我发现的是符号：_ZN7CvBoostC1EPKc存在于filepath / cps / thirdparty / opencv / lib / libml.so.4中

nm filepath/cps/thirdparty/opencv/lib/libml.so.4 | grep _ZN7CvBoostC1EPKc

不在文件filepath / cps / thirdparty / OpenCV-2.0.0 / lib / libml.so.4中，并以某种方式从MATLAB设置环境变量不起作用。在运行MATLAB之前导出LD_LIBRARY_PATH是必要的。
