/usr/bin/ld: cannot find -lopencv_dep_cudart
collect2: error: ld returned 1 exit status
src/caffe/CMakeFiles/caffe.dir/build.make:3284: recipe for target 'lib/libcaffe.so.1.0.0-rc3' failed

I have the same problem apparently it related to disable "Static Linking of Cuda" for OpenCV in CMake but I dont really know how to do that. Let me know if you manage to fix it

i still not fix it,let us keep waiting someone else who have experience on this problem to give us some tips~

I have solved this problem with the next steps I hope it helps you too.

1 Once you are in the build directory
ccmake ..
This will open like a gui in the terminal
2 if you press "t" you get all the possible options
3 then I have disable CUDA_USE_STATIC_CUDA_RUNTIME (if you are on teh flag just press enter to enable On or disbale OFF)
4. press c to configure
5 press g to generate
6 make all

Closing since it looks like the problem has been solved?

hi @ferchonavarro
thanks ,your solution works for me .
But I 'm wandering if disable CUDA_USE_STATIC_CUDA_RUNTIME means Caffe will not use CUDA?
Thank you very much !

[ferchonavarro]

@albertyou2 yes it should work and use CUDA I have tested it.

1)It is an excellent solution, thanks a lot.
2)Install ccmake by executing the following in a terminal:
sudo apt-get install cmake-curses-gui
(from https://askubuntu.com/questions/121797/how-do-i-install-ccmake)
3)Just open CMakeCache.txt and change CUDA_USE_STATIC_CUDA_RUNTIME from on to OFF also works.

I dont get the CUDA_USE_STATIC_CUDA_RUNTIME option in my GUI ?

I faced the same error, could not resolve it with the suggested solution.
I recommend following

to install caffe.
