yeah you are right. i compiled caffe with gcc-4.9 and leveldb from source with gcc-5. Compiling leveldb from source was suggested in some forum for 'undefined symbol: ...' but it was present still.For caffe, it is suggested in https://github.com/intel/caffe/wiki/Ubuntu-16.04-or-15.10-Installation-Guide to compile with gcc-4.9. This one is to avoid issues with Cuda 7.5. I compiled caffe in CPU ONLY mode so the step is unwarranted here.I removed leveldb and installed it again, and compiled caffe with gcc-5. I worked without any issue. No import error.Earlier i had similar issue with my lab desktop, it was throwing 'undefined symbol: _ZNK6google8protobuf7Message11GetTypeNameB5cxx11Ev caffe import error' while importing caffe in python environment. I solved the issue by compiling google's protobuf from source with gcc-5.
Best regards,
Srinath Balakrishnan

Hi Srinath,How did you install leveldb in the system? Looks like this is problem due to using different compilers for compiling leveldb and caffe (typically happens when you do package install of leveldb).Just 0.02$.Cheers,Bala

Everything gone well from make all command to make distribute command. Once i import caffe in python, the above problem shoots up. Need your help.System: ubuntu 16.04Python version: 2.7.1some suggested me to rebuild leveldb from source with gcc-5. I even tried it but the problem remains same.
