7 # GNU as and GNU ld might not work. See the INSTALL file.
12 # Configure will issue a WHOA warning. The problem is that
13 # Configure finds getzname, not tzname. If you're in the System V
14 # environment, you can set d_tzname='define' since tzname[] is
15 # available in the System V environment.
18 # Configure will issue a WHOA warning. The problem is that unistd.h
19 # contains incorrect prototypes for some functions in the usual
20 # BSD-ish environment. In particular, it has
21 # extern int getgroups(/* int gidsetsize, gid_t grouplist[] */);
22 # but groupslist[] ought to be of type int, not gid_t.
23 # This is only really a problem for perl if the
24 # user is using gcc, and not running in the SysV environment.
25 # The gcc fix-includes script exposes those incorrect prototypes.
26 # There may be other examples as well. Volunteers are welcome to
27 # track them all down :-). In the meantime, we'll just skip unistd.h
28 # for SunOS in most of the code. The POSIX extension is built with
29 # unistd.h because, even though unistd.h has problems, if used with
30 # care, it helps create a better POSIX extension.
35 You will probably see *** WHOA THERE!!! *** messages from Configure for
36 d_tzname and i_unistd. Keep the recommended values. See
37 hints/sunos_4_1.sh for more information.
40 # The correct setting of groupstype depends on which version of the C
41 # library is used. If you are in the 'System V environment'
42 # (i.e. you have /usr/5bin ahead of /usr/bin in your PATH), and
43 # you use Sun's cc compiler, then you'll pick up /usr/5bin/cc, which
44 # links against the C library in /usr/5lib. This library has
46 # If you are in the normal BSDish environment, then you'll pick up
47 # /usr/ucb/cc, which links against the C library in /usr/lib. That
48 # library has groupstype='int'.
50 # If you are using gcc, it links against the C library in /usr/lib
51 # independent of whether or not you are in the 'System V environment'.
52 # If you want to use the System V libraries, then you need to
53 # manually set groupstype='gid_t' and add explicit references to
54 # /usr/5lib when Configure prompts you for where to look for libraries.

67 # If you get the message "unresolved symbol '__lib_version' " while
68 # linking, your system probably has the optional 'acc' compiler (and
69 # libraries) installed, but you are using the bundled 'cc' compiler with
70 # the unbundled libraries. The solution is either to use 'acc' and the
71 # unbundled libraries (specifically /lib/libm.a), or 'cc' and the bundled
