1 # The MPE/iX linker doesn't complain about unresolved symbols, and so the only
2 # way to test for unresolved symbols in a program is by attempting to run it.
3 # But this is slow, and fraught with problems, so the better solution is to use
6 # MPE/iX lacks a fully functional native nm, so we need to use our fake nm
7 # script which will extract the symbol info from the native link editor and
8 # reformat into something nm-like.

71 # External functions and data items.
73 # Q: Does Configure *really* get *all* of these wrong?
75 # A: Yes. There are two MPE problems here. The 'undef' functions exist on MPE,
76 # but are merely dummy routines that return ENOTIMPL or ESYSERR. Since they're
77 # useless, let's just tell Perl to avoid them. Also, a few data items are
78 # 'undef' because while they may exist in structures, they are uninitialized.
80 # The 'define' cases are a bit weirder. MPE has a libc.a, libc.sl, and two
81 # special kernel shared libraries, /SYS/PUB/XL and /SYS/PUB/NL. Much of what
82 # is in libc.a is duplicated within XL and NL, so when we created libc.sl, we
83 # omitted the duplicated functions. Since Configure end ups scanning libc.sl,
84 # we need to 'define' the functions that had been removed.
86 # We don't want to scan XL or NL because we would find way too many POSIX or
87 # Unix named functions that are really vanilla MPE functions that do something
88 # completely different than on POSIX or Unix.
