~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you cannot find an appropriate binary pack for your platform you can
build the complete OpenFOAM from the source-pack. First you will need to
compile or obtain a recent version of gcc (we recommend gcc-4.1.?) for
compile or obtain a recent version of gcc (we recommend gcc-4.2.?) for
your platform which may be obtained from http://gcc.gnu.org/. Install the
compiler in $WM_PROJECT_INST_DIR/$WM_ARCH/gcc-4.1.? and change the gcc
compiler in $WM_PROJECT_INST_DIR/$WM_ARCH/gcc-4.2.? and change the gcc
version number in $WM_PROJECT_DIR/.bashrc and $WM_PROJECT_DIR/.cshrc as
appropriate and update the environment variables as in section 3.

A. Network settings
~~~~~~~~~~~~~~~~~~~
OpenFOAM requires a basic level of networking to be set up. Firstly, the
host name must be set - to test, type 'uname -a'. The running shell must
be tcsh, csh, bash or ksh - to test type 'echo $SHELL'
The user must be able to 'ping' the host machine itself (<host>) - to
test, type 'ping -c 1 <host>'
If the ping fails then it is possible that that the entry for the host
machine is missing, incorrect or duplicated in the /etc/hosts file. The
user can check this by typing 'grep <host> /etc/hosts' which should return
a single line, typically of the form:
<IPaddress> <host>.<domain> <host>
The <IPaddress> must correspond to that in the networking settings of the
machine which can also be checked by typing on Linux '/sbin/ifconfig'
which should produce lines of output that include something similar to the
following:
eth0 Link encap:Ethernet HWaddr ...
inet addr:<IPaddress> ...
If the user is connected to a network that uses dynamic IP addresses, they
must be particularly careful to ensure that an entry for their hostname/IP
exists in the /etc/hosts file. If the server frequently reallocates IP
addresses across the network, it is advisable that the /etc/hosts file is
updated automatically when any changes occur.
The user should also be able to contact any other machine that it needs
to, either a remote licence host or other machines that are being used
within some parallel computation. Essentially the user needs to be able to
ping these machines as described in preceeding sections.
The machine must have one of (or both) remote (rsh) and secure shell (ssh)
running on his/her account. To check whether rsh is running correctly, the
user should type 'rsh <host> ls'. Alternatively the user can check if ssh
is running correctly by typing 'ssh <host> ls'. In either case, the output
to the command should produce a file/directory listing for the current
directory and no other text. If neither command works, we recommend the
user set up rsh for their use as follows:
Check the rsh executable actually exists, e.g. the path to the executable
should be returned when typing 'which rsh'. Check with the system
administrator that rsh is enabled on the user's account; if not, request
that it is enabled. Create a '.rhosts' file in the $HOME directory
containing entries to access any machines they need to access, i.e. their
own machine and, if different, the licence host machine. The entries are
of the form: '<host> <user>'.
Remote shell accesses the .bashrc (or .cshrc) file and will not run
correctly if there is a problem with this file. In particular the user
should be careful with the following:
The ~/.cshrc (or ~/.bashrc) file should not contain errors that prevent it
from executing fully at startup; all error messages during execution of
the ~/.bashrc (or ~/.cshrc) file should be investigated and acted upon to
eliminate them. echo (print to screen) statements within ~/.bashrc (or
~/.cshrc) must not be executed during the running of rsh. This does not
mean that echo statements are forbidden from the ~/.cshrc (or ~/.bashrc)
file, but they must be enclosed in a control structure, e.g. an if
statement, that ensures they are not executed when rsh is executed.
For ~.bashrc:
if [ "$PS1" ]; then
echo "..."
fi
# or, alternatively
if /usr/bin/tty -s 2>/dev/null; then
echo "..."
fi
and, for ~.cshrc:
if ($?prompt) then ; echo "..." ; endif
