# 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Install the library and latest driver separately; the driver bundled with the library is usually out-of-date.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). |
