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