12 | # Configure will issue a WHOA warning. The problem is that | |
13 | # Configure finds getzname, not tzname. If you're in the System V | |

54000519 | 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 | |
bd89102f | 28 | # for SunOS in most of the code. (However, see ext/POSIX/hints/sunos_4.pl.) |

33 | You will probably see *** WHOA THERE!!! *** messages from Configure for | |
34 | d_tzname and i_unistd. Keep the recommended values. See | |
35 | hints/sunos_4_1.sh for more information. | |

38 | # The correct setting of groupstype depends on which version of the C |
39 | # library is used. If you are in the 'System V environment' | |
40 | # (i.e. you have /usr/5bin ahead of /usr/bin in your PATH), and | |
41 | # you use Sun's cc compiler, then you'll pick up /usr/5bin/cc, which | |
42 | # links against the C library in /usr/5lib. This library has | |
43 | # groupstype='gid_t'. | |
44 | # If you are in the normal BSDish environment, then you'll pick up | |
45 | # /usr/ucb/cc, which links against the C library in /usr/lib. That | |
46 | # library has groupstype='int'. | |
47 | # | |
48 | # If you are using gcc, it links against the C library in /usr/lib | |
49 | # independent of whether or not you are in the 'System V environment'. | |
50 | # If you want to use the System V libraries, then you need to | |
51 | # manually set groupstype='gid_t' and add explicit references to | |
52 | # /usr/5lib when Configure prompts you for where to look for libraries. | |

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