18 | Whether you should use sun1, sun2 or sun3 depends on the | |
19 | VERSION OF THE OPERATING SYSTEM | |
20 | you have. There are three machine types for different versions of | |
21 | SunOS. All are derived from Berkeley 4.2, meaning that you should | |
22 | use -opsystem=bsd4-2. Emacs 17 has run on all of them. You will | |
23 | need to use sun3 on Sun 2's running SunOS release 3. | |
24 | ||
25 | For SunOS release 4 on a Sun 3, use -machine=sun3 and | |
26 | -opsystem=sunos4. See the file share-lib/SUNBUG for how to solve | |
27 | problems caused by bugs in the "export" version of SunOS 4. | |
