Here is (straight from the technical department) the explanation for why this happens. To make Mathematica start quickly, we do a special procedure at the end of the installation process called "dumping." What we do is load a bunch of packages (like integral tables and such) into memory, and then create a new a.out file, mathexe, from the current running program. Creating a coff file from a memory image requires creating and manipulating an object file. Between 10.1 and 10.2, changes to the Apollo coff file format causes dumped Mathematica to be incompatible. So, you need to create a second dumped version on SR10.2 if you have both OS 10.1 and 10.2 present. The easy way to do this is to reinstall on the 10.2 system. Make certain that 10.1 nodes link to the 10.1 version, and 10.2 nodes link to the 10.2 version. If you are really short on disk space, or can't do this for some other reason, you can look for a program called mathraw shipped with your distribution. Mathraw is the undumped version of Mathematica, and should run at both 10.1 and 10.2. You will need to play with your init.m file to load the correct packages. It will start up much slower than the dumped version. Latest version of Mma for Apollos is 1.2.6. There is no timetable yet for a new version, but rest assured, there will be a new one someday. ----------------------------------------------------------------------------------------- Leland Ray leland@wri.com Systems Administration -- Unix Platforms {whatever}!uiucuxc!wri!leland Wolfram Research, Inc.
