--- title: "Installation: RHEL / Fedora / CentOS" --- # RHEL / Fedora / CentOS Installation **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://storage.googleapis.com/google-code-archive-downloads/v2/code.google.com/google-glog/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 Install the library and latest driver separately; the driver bundled with the library is usually out-of-date.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](installation.html#compilation).
