cannot find -lcaffe when run make_deep_image_analogy.sh

[taneta]

I already have preinstalled caffe docker bvlc/caffe and trying to make the project, but get this error:

deep_image_analogy/source/lbfgs.cu:17:9: warning: #pragma once in main file
 #pragma once
         ^
/usr/bin/ld: cannot find -lcaffe
collect2: error: ld returned 1 exit status

How can I fix it? I have caffe path exported to LD.

When I change the line:
-lcaffe \
in make_deep_image_analogy.sh to:
-L/opt/caffe/python \
it returns:

ln -s /caffe/build/lib/libcaffe.so /usr/lib/libcaffe.so

It works for me

@zhengziqiang
Linking the library failed to work for me. I no longer get the /usr/bin/ld: cannot find -lcaffe error message, but now this is returned:

I do not know how to comprehend that. What I can tell you is that I did not make Caffe from the build provided in this repository since its an older build without compatibility for CUDNN > v5.1, rather I compiled Caffe from BVLC's master repository. Also, I do have a previous build of Deep Image Analogy, which runs successfully on this same machine, but it is from otrimegistro's fork (https://github.com/otrimegistro/Deep-Image-Analogy#deep-image-analogy) for Linux support. I also built Caffe from that fork when I only had CUDNN v5.1 installed, which is supported in that build of Caffe.

Are there dependencies for this project included in this repository that is not included in BVLS's master repository of Caffe?

[tisawe]

I successfully made the project by installing the master branch of Caffe and copying the specific files for this project into my directory of Caffe's master branch. Added '~/caffe/build/lib' to my 'LD_LIBRARY_PATH' and edited the scripts documented in the readme to work with my environment. Then I ran 'config_deep_image_analogy.sh' and 'make_deep_image_analogy.sh', and a working executable was made.

Hi I have the same issue
I downloaded and compiled caffe successfully
No when I try to compile the project I got the following error
/usr/bin/ld: cannot find -lcaffe
as you mentioned LD_LIBRARY_PATH
my source path is /root/deeplearnng/Deep-Image-Analogy-linux
and my caffe path is /root/deeplearning/caffe-rc5/.build_release/lib
how can I set LD_LIBRARY_PATH
thanks and regards

@tisawe
I tried your copy methods and build deep-image-analogy in the master branch of Caffe. However, I still got the same error as before.

Could you give me more suggestions or details about how you solved this problem?
Thanks a lot!
