This shows how to install rasmol on ROCKS 5.4.3 which is based on CentOS.
Rasmol 2.7.5.2
wget http://www.rasmol.org/software/RasMol_Latest.tar.gz
tar xvf
cd RasMol-2.7.5.2/src/
./build_all.sh
If all went well
sh rasmol_run.sh
should start it
NOTE: this doesn't install rasmol anywhere -- it builds it and allows you to run it from the src directory. Put an alias in your ~/.bashrc pointing towards the rasmol_run script e.g.
alias rasmol='sh /home/me/.rasmol/RasMol-2.7.5.2/src/rasmol_run.sh'
Note that prior to this you will have to set up a working build environment, e.g.
sudo yum install gcc gcc-c++ gcc-gfortran cpp
