Compilation problem, undefined references

[tie...@gmail.com]

After following the instalation instruccions, on kubuntu 14.10 with cuda 7.0

sudo apt-get install libprotobuf-dev libleveldb-dev libsnappy-dev libopencv-dev libboost-all-dev libhdf5-serial-dev

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev protobuf-compiler

sudo apt-get install libatlas-base-dev

make all throws the following linker errors:

../lib/libcaffe.so: undefined reference to `google::protobuf::internal::kEmptyString'
../lib/libcaffe.so: undefined reference to `H5LTfind_dataset'
../lib/libcaffe.so: undefined reference to `H5LTmake_dataset_double'
../lib/libcaffe.so: undefined reference to `H5LTread_dataset_float'
../lib/libcaffe.so: undefined reference to `H5LTmake_dataset_float'
../lib/libcaffe.so: undefined reference to `H5LTget_dataset_info'
../lib/libcaffe.so: undefined reference to `H5LTread_dataset_double'

protoc --version:

libprotoc 2.5.0

Any hint on what I'm missing here?
Thx.
