CalcHEP

This is the most difficult to work under Windows. This is because the program is not an .exe file as the case of QGRAF, and it assumes an Unix/Linux logic of files and subdirectories. I did not find any help on the web and my suggestion is to install a virtual machine in Windows from where you can run a Linux system. I have tried it and it works. I give here the steps of what I did on a PC running Windows 7 with an i3 CPU and 4GB of RAM.

• Download the virtual machine (VM)
  I used the VirtualBox provided by Oracle. You can get it at https://www.virtualbox.org/wiki/Downloads or for more specific versions of the OS here

• Install the VM
  Follow the steps of the installer. The only important thing to decide is the amount of RAM and disk space. I tested that you need at least 1 GB RAM and at least 10 GB disk space. Better more, if you can. The memory settings can be changed latter. They are in use only when you use the VM, of course.

• Install Linux
  I installed the latest Ubuntu 12.04. This already installed the C compiler gcc. The default desktop is heavy and the icons are too large. It is better to install a lighter desktop like lubuntu. For that you use the command

  sudo apt-get install lubuntu-desktop

  and then choose it in the login screen. Next time you login this will be the default.

• Extra programs
  

  You need to install the gfortran compiler. The instructions are

  sudo apt-get install gfortran

• CalcHEP
  
  • Installation
    Follow the instructions on the CalcHEP web page.
  • Graphical display
    You need to install the libX11 library to have a graphical display. In Ubuntu you just do

    sudo apt-get install libX11-dev

    Then follow the rest of the installation instructions for CalcHEP.

  • Problems with X11
    You need to have the gsfonts available for X11. In some cases you should have the following lines in the xorg.conf

    Section "Module"
Load "type1"
EndSection

• Install QGRAF
  Download the files and compile with gfortran. The command is

  gfortran qgraf-3.1.3.f -o qgraf

  qgraf is just the name of the binary executable file

Have fun.
