1. Install gcc (Takes very long time, about 6 hours)

   1. go to ~/src

   $ cd ~/src
   

   2. install gcc (for cmake, takes few HOURS)

   $ mkdir gcc_src
   $ cd gcc_src
   $ curl -L -O http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-7.3.0/gcc-7.3.0.tar.gz

   $ cd gcc-7.3.0
   $ contrib/download_prerequisites
   $ cd ../objdir
   $ ../gcc-7.3.0/configure --prefix=$HOME/usr/local/gcc --disable-multilib
   $ make && make install
   

   update PATH and LD_LIBRARY_PATH to ~/.bashrc, but don't modify original export just append additional paths

   export LD_LIBRARY_PATH=$HOME/usr/lib:$HOME/usr/local/gcc/lib64:$HOME/usr/local/gcc/lib:$LD_LIBRARY_PATH
   export PATH=$HOME/usr/bin:$HOME/usr/local/gcc/bin:$PATH
   

   then restart remote shell or use source command

   $ source ~/.bashrc
   

   Check gcc is properly installed

   $ gcc --version

       $ tar zxvf ThirdParty-v1806.tgz
       

    2. Add new environment variables for MPI to ~/.bashrc

       export MPI_ROOT=$MPIHOME
       

    3. Change OpenFOAM bashrc

       • open OpenFOAM bashrc

       $ vim OpenFOAM_v1806/etc/bashrc
       

       • change WM_MPLIB variable to use SYSTEMMPI

       export WM_MPLIB=SYSTEMMPI
       

       • create mpi-system file

       vim etc/config.sh/mpi-system
       

       • save the file with following lines

       export MPI_ROOT=$MPIHOME
       export MPI_ARCH_FLAGS="-DOMPI_SKIP_MPICXX"
       export MPI_ARCH_INC="-isystem $MPI_ROOT/include"
       export MPI_ARCH_LIBS="-L$MPI_ROOT/lib -lmpi"
       

    4. type following commands to shell prompt (use parallel build for faster build)

       $ export WM_NCOMPPROCS=4
       

    5. Follow official build guide

       $ source etc/bashrc
       $ ./Allwmake
       

    6. TroubleShooting

       • If you stuck at INT32_MAX error, read this and apply the patch manually but location is different; modify this file wmake/rules/General/Gcc/c++
