18# Default on 3.2v5 is to use dynamic loading.
19# To use static linkink instead, use to sh Configure -Dusedl=n

21# Warning: - to use dynamic loading with gcc, you need gcc 2.8.0 or later

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.
