26 | # NOTES: | |
27 | # ----- | |
28 | # | |
29 | # I Have removed inclusion of ODBM_File for OSR5 | |
30 | # because it core dumps and make tests fails. | |
31 | # | |
32 | # Support for icc compiler has been removed, because it 'breaks' | |
33 | # a lot of code :-( | |
34 | # | |
35 | # It's *always* a good idea to first make a static link to be sure to | |
36 | # have all symbols resolved with the current choice of libraries, since | |
37 | # with dynamic linking, unresolved symbols are allowed an will be detected | |
38 | # only at runtime (when you try to load the module or worse, when you call | |
39 | # the symbol) | |
40 | # | |
41 | # The best choice of compiler on OSR 5 (3.2v5.*) seems to be gcc >= 2.8.0: | |
42 | # -You cannot optimize with genuine sco cc (miniperl core dumps), | |
43 | # so Perl is faster if compiled with gcc. | |
44 | # -Even optimized for speed, gcc generated code is smaller (!!!) | |
45 | # -gcc is free | |
46 | # -I use ld to link which is distributed with the core OS distribution, so you | |
47 | # don't need to buy the developement kit, just find someone kind enough to | |
48 | # give you a binary release of gcc. | |
