General dependencies
sudo yum install protobuf-devel leveldb-devel snappy-devel opencv-devel boost-devel hdf5-devel
Remaining dependencies, recent OS
sudo yum install gflags-devel glog-devel lmdb-devel
Remaining dependencies, if not found
# glog
wget https://google-glog.googlecode.com/files/glog-0.3.3.tar.gz
tar zxvf glog-0.3.3.tar.gz
cd glog-0.3.3
./configure
make && make install
# gflags
wget https://github.com/schuhschuh/gflags/archive/master.zip
unzip master.zip
cd gflags-master
mkdir build && cd build
export CXXFLAGS="-fPIC" && cmake .. && make VERBOSE=1
make && make install
# lmdb
git clone https://github.com/LMDB/lmdb
cd lmdb/libraries/liblmdb
make && make install
Note that glog does not compile with the most recent gflags version (2.1), so before that is resolved you will need to build with glog first.
CUDA: Install via the NVIDIA package instead of yum to be certain of the library and driver versions.
Install the library and latest driver separately; the driver bundled with the library is usually out-of-date.
+ CentOS/RHEL/Fedora:
BLAS: install ATLAS by sudo yum install atlas-devel or install OpenBLAS or MKL for better CPU performance. For the Makefile build, uncomment and set BLAS_LIB accordingly as ATLAS is usually installed under /usr/lib[64]/atlas).
Python (optional): if you use the default Python you will need to sudo yum install the python-devel package to have the Python headers for building the pycaffe wrapper.
Continue with compilation.
