Caffe installation error when running make test

[Raghu Ram]

I am trying to install Caffe on a Ubuntu 14.04 system. When I run make all, the compilation runs smoothly. When I move onto the next step, make test, I get the following output:

CXX/LD -o .build_release/test/test_all.testbin src/caffe/test/test_caffe_main.cpp

Any help on resolving this would be much appreciated.

you have two versions of opencv which you have set the paths for both in your bash file.

removing one of them would solve the issue.

Some one tell in other theard that can change "DBUID-EFF=0" but i can't know how to change it in cmake

[Raghu Ram]

Hi Majid, can you please let me know how to do it? I edited the Makefile as per the instructions given here (http://stackoverflow.com/questions/34125052/caffe-with-opencv-3-and-nvidia-digits-opencv-version-conflict-2-4-vs-3-0/34211100). When I do that, I get errors like this.

/usr/bin/ld: cannot find -llibopencv_highgui.so.2.4
/usr/bin/ld: cannot find -llibopencv_imgproc.so.2.4

Seems you are missing boost too.

Well the safest way for the OpenCV problem is to have only one version installed. If you need both, install only one into the standard paths (with your package manager) and install the other manually to some other path (e.g. /usr/local/opencv-3.0). Then use only one of both in the Makefile.config.

Jan

[S.Majid Azimi]

include the pkg-config path for your opencv installation and remove others and also do for ld_library_path

do both of them in your bash file

and check with

$pkg-config --libs opencv

$pkg-config --cflags opencv

to check if you've done correctly.

Thanks for the help, but I am ending up with the same errors over and over again. I removed all the versions of OpenCV and reinstalled OpenCV 2.4.9 following the instructions outlined here (http://www.samontab.com/web/2014/06/installing-opencv-2-4-9-in-ubuntu-14-04-lts/). Next, I type this in the terminal
 export LD_LIBRARY_PATH =/usr/local/lib and when I run make test, I get the following:

CXX/LD -o .build_release/test/test_all.testbin src/caffe/test/test_caffe_main.cpp

/usr/bin/ld: cannot find -llibopencv_core.so.2.4
/usr/bin/ld: cannot find -llibopencv_highgui.so.2.4

/usr/bin/ld: cannot find -lopencv_imgproc.so.2.4

/usr/bin/ld: cannot find -llibopencv_imgcodecs.so.2.4
/usr/bin/ld: cannot find -llibopencv_core.so.2.4
/usr/bin/ld: cannot find -llibopencv_highgui.so.2.4
/usr/bin/ld: cannot find -llibopencv_imgproc.so.2.4
collect2: error: ld returned 1 exit status
make: *** [.build_release/test/test_all.testbin] Error 1

The output of pkg-config --libs opencv gives me /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_ocl.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_superres.so /usr/local/lib/libopencv_ts.a /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so /usr/local/lib/libopencv_viz.so /usr/lib/x86_64-linux-gnu/libXext.so /usr/lib/x86_64-linux-gnu/libX11.so /usr/lib/x86_64-linux-gnu/libICE.so /usr/lib/x86_64-linux-gnu/libSM.so /usr/lib/x86_64-linux-gnu/libGL.so /usr/lib/x86_64-linux-gnu/libGLU.so -ltbb -lrt -lpthread -lm -ldl.

Similarly, the output of pkg-config --cflags opencv gives me the following -I/usr/local/include/opencv -I/usr/local/include. From this, I am assuming that opencv installation has gone smoothly and I have followed what you have asked me to do. I did not set the LD_LIBRARY_PATH in a path file, because I came across multiple websites warning against permanently setting the LD_LIBRARY_PATH. Is there something I am not picking up here or doing wrong?

[Jan C Peters]

Is there a specific reason you compiled opencv from source? If not you should rather stick to the stock version provided by your package manager. On Ubuntu 14.04 this would be the package libopencv-dev. This will install OpenCV 2.4.8. You can do a source build, but then you'll have to provide all the include and lib paths for compilation and linking, and also the respective LD_LIBRARY_PATH when running a program that uses the OpenCV libs. Stock version is much easier in that regard.

As for your problems: the LD_LIBRARY_PATH is not used during compilation and linking, so that export LD_LIBRARY_PATH=... won't do you any good here. It is needed when you are _runnning_ (or loading) a program that uses the opencv libs.

The output that pkg-config gives you is intended to be provided to the compiler (in the case of --cflags) and the linker (in the case of --libs), when compiling and linking some program that wants to use OpenCV.

Conveniently, the pkg-config based inclusion of the OpenCV library is already arranged for you in the Makefile.config of caffe. Just uncomment the USE_PKG_CONFIG := 1 line to make it take effect. The compilation should go smoothly then.

Hi Raghu,

Have you found some solution for this issue ? I am also having same error while running make test while i already have installed boost 1.58 .
Thank you in anticipation
