The ./install compiles a fortran program to get things rolling, it looks like either your g77 doesnt exist or you need to edit the installer script. If you have gfortran installed rather than g77, then edit the ./install and replace g77 with gfortran.

In fact thats true throughout Johnathan’s guide. If you do the above, the installer will start, and then fail. Edit the makemcnp script and replace g77 with gfortran, also remove the “./” from fsplit.

Run makemcnp and then you’re done.

Hope that helps

Yeah I struggled to find a how-to for ages until I realized that I had to work it out myself. It a bugbear of mine that the opensource/scientific community often keep the entry level too high for end-users.

As for the problems you’re having I’d love to help but my MacBook Pro died two days ago and I’d in for repair so I can’t look at the directory structure as the install is taking place.

Your error (forgive me if you know this already) means that mcsetp is not located in the current working directory (signified by the ./). Now it’s been a while and I can’t be sure as I can’t work through the install again at the moment but the mcsetup file is copied to your hard disk when unzipping the MCNP distribution when you begin (the part with the gunzip command).

From your output it seems that you’re current working directory is / rather than (for example) /Applications/mcnp/mcp4c2. But as the install has begun I’m guessing that I’m wrong in thinking this.

So first check that the folder with install also contains mcsetup. If not, then I’d start again making sure that the unzip process works properly.

Let me know if this helps.

Thank you for what seems to be the only tutorial online on how to install this for the Mac! I have followed your directions and have hit a snag at the install stage and would appreciate your advice. I get the following error message shown below.

Many thanks,

Phil

Thanks for the help. I’ve been pretty busy at work and haven’t had any time to try to set this up. I’m hoping to get a chance within the next few weeks. As soon as I try, I’ll let you know the results.

No follow-up at the moment unfortunately! Would be worth checking back here every now and then. One day I’ll get the 5/X upgrade too.

And you’re welcome for the tutorial
