28 | # NOTES: |
---|
29 | # ----- |
---|
30 | # |
---|
31 | # I Have removed inclusion of ODBM_File for OSR5 |
---|
32 | # because it core dumps and make tests fails. |
---|
33 | # |
---|
34 | # Support for icc compiler has been removed, because it 'breaks' |
---|
35 | # a lot of code :-( |
---|
36 | # |
---|
37 | # It's *always* a good idea to first make a static link to be sure to |
---|
38 | # have all symbols resolved with the current choice of libraries, since |
---|
39 | # with dynamic linking, unresolved symbols are allowed an will be detected |
---|
40 | # only at runtime (when you try to load the module or worse, when you call |
---|
41 | # the symbol) |
---|
42 | # |
---|
43 | # The best choice of compiler on OSR 5 (3.2v5.*) seems to be gcc >= 2.8.0: |
---|
44 | # -You cannot optimize with genuine sco cc (miniperl core dumps), |
---|
45 | # so Perl is faster if compiled with gcc. |
---|
46 | # -Even optimized for speed, gcc generated code is smaller (!!!) |
---|
47 | # -gcc is free |
---|
48 | # -I use ld to link which is distributed with the core OS distribution, so you |
---|
49 | # don't need to buy the developement kit, just find someone kind enough to |
---|
50 | # give you a binary release of gcc. |
