Warning! Be aware, that Mac OS ix not Linux, installation of any GNU (or GNU-based) software can cause problems!

Here is a set of instructions for installing CompHEP on a Macintosh running OS X.

Before doing anything else,

• install the Apple ���Developers' Disk��� that came with your operating system
• install X11 from the OS disk or from the Apple web site
• go to Fink ( http://fink.sourceforge.net/ or any other GNU software repository), download the fink application and ���Fink Commander���, and then use this to download the binary files for:

  gfortran   (fortran 77 compiler)

• download the last version of the software from the comphep web site, http://comphep.sinp.msu.ru.
• Unpack the tar and put the resulting directory in convenient place.
• Run ��� ./configure ���help��� and read the help page. If you need ROOT you can download it from http://root.cern.ch (for Mac!!!)
• Run ���make���.
• Run ���make setup WDIR=path_to_your_working_dir_for_comphep���.

We have tested these instructions on a particular machine running under OS 10.4. and with the following versions of GNU software:

1. GNU make 3.80
2. gcc 4.0.1
3. gfortran 4.3.0

If you have a problem on your machine, please send your report to us at comphep-devel@theory.sinp.msu.ru giving the specific versions of the OS and all software.
