Compiling C++ software Using Mex

Hello,

I am trying to compile a .cpp code that uses libraries such as opencv 3.0, ceres, boost, and tbb. Below is the output. I have Ubuntu 14.04 and MATLAB 2015a. I have more than one version of opencv (e.g., 2.5, 3.0) in my machine. The one needed for the code is 3.0. So I use the -L to indicate where the path for opencv3.0 libraries are yet the mex command says it can't find them. Anyone know what's going on?

Thanks

[Harsheel]

Replace -llibopencv_core and -llibopencv_highgui to:

-lopencv_core -lopencv_highgui

For -llibname, MATLAB expands libname to liblibname.so

Thank you. Yes. I found out that out while reading a CUDA website. However, it has not solved my problem. Most recent output below. It looks like is missing the opencv linked libraries; however, they are provided.
