Install CitcomS

Q: What is the dependency of CitcomS-2.2 or later?

CitcomS-2.2 or later depends on the MPI library. In addition, if you like to use the Pyre framework (which provides an ease-of-use environment), you will need Python 2.3 or newer. (Note that if your machine is 64-bit, you will need Python 2.4.)

Q: I want to use CitcomS in the old way (pure C code, no Python). How can I do that?

You can configure CitcomS to only use C code by running:

    ./configure --without-pyre

before compiling the code.

Q: What does it mean when "configure" reports this error message:

    OverflowError: signed integer is greater than maximum

Are you on a 64-bit machine? If so, you will need to upgrade your Python to v2.4 or newer. Python 2.3 or earlier is not 64-bit safe.

Q: The gcc/python/mpi on my system is too old, but I don't have the privilege to update the software. How can I install gcc/python/mpi under my home directory?

1. Get the tarball of gcc/python/mpi and untar it
2. cd into the untarred directory
3. Run the following to install the package under the directory $HOME/opt:

       ./configure --prefix=$HOME/opt && make && make install 
   

4. Add $HOME/opt/bin into your $PATH and (maybe) $HOME/opt/lib into your $LD_PATH_LIBRARY.
