.build_release/lib/libcaffe.so: undefined reference to ...

When I'm trying to compile caffe, I get the following error message:

Any suggestion as for what could be causing the trouble?

Maybe you can check is there any dependent library included in Makefile.config

Hi,

I'm facing the same problem. 

I tried to solve it by installing the opencv library manually from scratch using the last version in GitHub, but it was not solved. I also found some possible solutions related to the version I'm using for protobuf. I installed a previous version of protobuf but it didn't work, either. 

I will keep trying other possible solutions and if anybody gets a solution it will be more than welcome =)
