Installing XIOS

Procedure

Use PuTTY to log in to the server as the root user.
Go to the directory generated after the decompression.
```
cd /path/to/XIOS
```

Download the XIOS source code from the Internet.

svn co -r 703 https://forge.ipsl.jussieu.fr/ioserver/svn/XIOS1/branches/xios-1.0/ xios-1.0

Install the system dependencies.
```
yum install -y perl-lib* boost-*
```
Go to the directory generated after the decompression.
```
cd xios-1.0
```

Modify the bld.cfg file.

Open the bld.cfg file.
```
vi bld.cfg
```

Press i to enter the edit mode and modify the file as follows:

search_src           true
src::zzz .
#src::date $PWD/extern/boost/src/date_time
src::blitz $PWD/extern/blitz/src
src::netcdf $PWD/extern/netcdf4
bld::lib xios
bld::target libxios.a
#bld::target generate_fortran_interface.exe
#bld::target xios_server.exe test_client.exe parse_xml.exe test_complete.exetest_xios_interface.exe
bld::exe_dep

Press Esc, type :wq!, and press Enter to save the file and exit.

Create an arch-AARCH64_GNU_LINUX.env configuration file.

Create an arch-AARCH64_GNU_LINUX.env configuration file.
```
vi arch/arch-AARCH64_GNU_LINUX.env
```

Press i to enter the edit mode. Create and edit the arch-AARCH64_GNU_LINUX.env file.

export HDF5_INC_DIR="/path/to/HDF5/include"
export HDF5_LIB_DIR="/path/to/HDF5/lib"

export BOOST_LIB_DIR="/usr/lib64/"
export BLITZ_INC_DIR="/path/to/BLITZ/include"
export BLITZ_LIB_DIR="/path/to/BLITZ/lib"

Edit the file based on the actual environment variables and the dependency library installation path.

Press Esc, type :wq!, and press Enter to save the file and exit.

Create an arch-AARCH64_GNU_LINUX.fcm configuration file.
