1. Required

   a) gcc 4.9.3
   b) boost 1_55_0
   c) CUDA_8.0 or CUDA_7.5
   

2. Install gcc-4.9.3

   first you should download gcc-4.9.3.tar.bz2, then
   

   # yum install libmpc-devel mpfr-devel gmp-devel
   $ tar xvfj gcc-4.9.3.tar.bz2
   $ cd gcc-4.9.3
   $ ./configure --disable-multilib --enable-languages=c,c++
   $ make -j 4
   # make install
   $ ln -s /usr/local/lib64/libstdc++.so.6.0.20 path/LiNMT // where you want to run LiNMT, you should link libstdc++.6.0.20
   

3. Install boost_1_55_0

   first you should download boost_1_55_0.tar.gz, then
   

   $ rpm -qa boost // if show something, then use the second command, otherwise use the third command
   # yum remove boost // uninstall boost, then use 'rpm -qa boost', you will see nothing
   $ tar xzvf boost_1_55_0.tar.gz
   $ cd boost_1_55_0
   $ ./bootstrap.sh
   $ ./b2
   $ ./b2 install
   

4. Install CUDA_8.0 or CUDA_7.5

   $ ./cuda_8.0.44_linux.run --tmpdir=. // all option is 'yes'
   $ sudo vi /etc/profile.d/cuda.sh // write enviroment variable
   # export PATH=$PATH:/usr/local/cuda/bin
   # export LD_LIBRARY_PATH=$PATH:/usr/local/cuda/lib64
   $ source /etc/profile.d/cuda.sh
   $ nvidia-smi // check
   

5. Compile the LiNMT

   $ cd LiNMT/
   $ tar xzvf eigen.tar.gz
   $ make
   $ vim ~/.bashrc // add 'export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH'
   $ source ~/.bashrc
   

6. Training a NMT model

   $ cd LiNMT/scripts/
   $ perl LiNMT.pl -config ../config/LiNMT-nmt-training.config
   

7. Decoding a file with source sentences

   $ cd LiNMT/scripts/
   $ perl LiNMT.pl -config ../config/LiNMT-nmt-decoding.config
