Caffe: Build errors, undefined cv::imread() cv::imencode() ...

Any ideas?

See my answer in #2286.
Seems like libc++ related problem.

[shelhamer]

Please ask on the caffe-users group.

@sakrig I have the same problem, but it is solved after using cmake to configure your project.

change Makefile:
LIBRARIES += glog gflags protobuf leveldb snappy \
lmdb boost_system hdf5_hl hdf5 m \
opencv_core opencv_highgui opencv_imgproc
add :opencv_imgcodecs solve my problem

[fabioperez]

@northeastsquare I'm having the same issue. When I add opencv_imgcodec, I get the following error: /usr/bin/ld: warning: libopencv_core.so.3.0, needed by /opt/lib/libopencv_imgcodecs.so, may conflict with libopencv_core.so.2.4

[pranavmaneriker]

@fabioperez
Had the same issue. For me, uninstalling opencv-3.0.0 (using a make uninstall) and installing opencv-2.4.11, followed by building caffe again worked.

It seems like sticking to opencv-<2.4.11 is a good option for now.

[bhack]

Try to use Cmake build

[wlike]

add opencv_imgcodecs to LIBRARIES in Makefile solved my problems too

[blackCmd]

@northeastsquare
oh! thank you !! it's work !

[abouzahir]

i solved this problem by adding -lopencv_imgcodecs to my makefile as follows
OPCV = -L/usr/local/lib -lopencv_core -lopencv_highgui -lopencv_features2d -lopencv_flann -lopencv_imgproc -lopencv_imgcodecs

and the $(OPCV) must be placed after the objects needing them

[colek42]

cmake solved it for me!!!

[blackCmd]

oh sorry.. i'm late

@bhack : how does one do it?!

[mai00dou]

@northeastsquare,Thanks to you,I have solved the problem used your method.

[Elpidam]

same here! Thanks for the help!

[aharishkumar]

@northeastsquare : thank you. It worked

[aharishkumar]

Hey _make all_ worked fine. But when I ran _make test_ it gave mountain of errors.

Please ask installation queries on caffe-users.

It looks like you don't have boost linked. Try reinstalling boost and linking it again.

[aharishkumar]

I had to link boost_filesystem in the libraries in make file. Now its working.
Thank you

[blackCmd]

Good nice work = )

By setting OPENCV_VERSION := 3 can also solve this problem.

Hey @Greencurity, where should i write this? Thank you!
