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 |
84902520 |
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 |

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