Caffe: make all error

[rmanor]

I get the following errors when I do 'make all', although I installed all the required dependencies.

/usr/bin/ld: cannot find -lcblas
/usr/bin/ld: cannot find -latlas

Using Ubuntu 12.10. Thanks.

The same happens with openblas. It's weird because I see earlier commands with -lcblas -latlas that works and all of sudden it fails.

Had the same problem on Ubuntu 15.04, the solution from ^link hasn't worked, it appeared that one has to install libatlas-base-dev. Maybe it's worth to add it to dependencies.

install libatlas-base-dev solve my problem. Thanks @inexxt .

libcblas.so may also present in subdirectory of /usr/lib. Check whether libcblas.so is present in /usr/lib/atlas. If exists, then include this path.

I had this problem any one with solution...

Ubuntu 14.04, installing libatlas-base-dev solved my problem too.

@habemen
Long shot but I have the same problem, any ideas how to fix it?

[nerdykamil]

@duygusar pkg-config --modversion opencv run this command on terminal to check opencv version if it is not version 3 then comment out OPENCV_VERSION := 3 in makefile.config

[duygusar]

@nerdykamil thanks but it is opencv3.3 as I intended, I installed it from build myself and as far as I know 3 is recommended for computation > 6.0 GPUs. Opencv 3.3 has some changes Caffe build doesn't support yet (can't refer to some files as opencv separated them but content is the same) but what I did solves the problem:

I am not sure what worked exactly since I didn't take notes, as far as I remember

1.First, make sure you run this to satisfy all python requirements
sudo sh -c 'for req in $(cat requirements.txt); do pip install $req; done'
2.Then Follow the answer to this question religiously (for OpenCV 3.3 at least but possibly for 3.2 as well):

On Ubuntu 18.04, installing libatlas-base-dev solved my problem as well.

Can you take a look at this problem?

This is the error that i got when i tried to make caffe:

rheza@rheza-VirtualBox:~/Documents/BirdWatcher/caffe$ make all
AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0-rc3

Any help will be appreciated. Thank you!
