The text above when "referência indefinida" must read "indefined reference"

Error in pfstools compilation. Seems a error in previous "ilmbase" compilation (that is not shown)  that the pthread is not detected (or it is not installed in OS(Ubuntu 16.04)) by the configure 

Can you help me?

Thanks

Which version of pfstools was that? 

Which OpenEXR packages are installed (dpkg -l "*openexr*")?

You need to install 

libopenexr-dev

sudo apt install libopenexr-dev

Something must be wrong with OpenEXR installation. 

You can run 

make VERBOSE=1

to see the full command line used to link the program. Then, you can compare the libraries used with what is returned by:

>  pkg-config --libs OpenEXR

-lIlmImf -lImath -lHalf -lIex -lIexMath -lIlmThread -lpthread

My guess is that -lpthread is missing. You may need to edit CMakeCache.txt to add the missing library.

I had to replace -lpthread by -pthread (text) in "link.txt" files of ...inexr and ...outexr projects

It solved that problem. Now it is a problem in Mex files of Matlab. But I will try to solve myself before post something

Thanks

Now, it is giving this problem. I did not found opencv_nonfree in any place with synaptic and apt-get and in my computer. I only found a libopencv_nonfreexxx (library) in my Matlab instalation

Despite I found "/usr/include/opencv2/features2d/features2d.hpp"

Can anyone give some clues?

Thanks

Please check if the answer from

http://stackoverflow.com/questions/27481849/include-nonfree-opencv-2-4-10-on-ubuntu

solves the issue.
