dnl |
| 776 |
|
|
dnl This test is for network applications that need socket() and |
| 777 |
|
|
dnl gethostbyname() -ish functions. Under Solaris, those applications need to |
| 778 |
|
|
dnl link with "-lsocket -lnsl". Under IRIX, they should *not* link with |
| 779 |
|
|
dnl "-lsocket" because libsocket.a breaks a number of things (for instance: |
| 780 |
|
|
dnl gethostbyname() under IRIX 5.2, and snoop sockets under most versions of |
| 781 |
|
|
dnl IRIX). |
| 782 |
|
|
dnl |
| 783 |
|
|
dnl Unfortunately, many application developers are not aware of this, and |
| 784 |
|
|
dnl mistakenly write tests that cause -lsocket to be used under IRIX. It is |
| 785 |
|
|
dnl also easy to write tests that cause -lnsl to be used under operating |
| 786 |
|
|
dnl systems where neither are necessary (or useful), such as SunOS 4.1.4, which |
| 787 |
|
|
dnl uses -lnsl for TLI. |
| 788 |
|
|
dnl |
| 789 |
|
|
dnl This test exists so that every application developer does not test this in |
| 790 |
|
|
dnl a different, and subtly broken fashion. |
| 791 |
|
|
dnl |
| 792 |
|
|
dnl It has been argued that this test should be broken up into two seperate |
| 793 |
|
|
dnl tests, one for the resolver libraries, and one for the libraries necessary |
| 794 |
|
|
dnl for using Sockets API. Unfortunately, the two are carefully intertwined and |
| 795 |
|
|
dnl allowing the autoconf user to use them independantly potentially results in |
| 796 |
|
|
dnl unfortunate ordering dependancies -- as such, such component macros would |
| 797 |
|
|
dnl have to carefully use indirection and be aware if the other components were |
| 798 |
|
|
dnl executed. Since other autoconf macros do not go to this trouble, and almost |
| 799 |
|
|
dnl no applications use sockets without the resolver, this complexity has not |
| 800 |
|
|
dnl been implemented. |
| 801 |

|
dnl |

dnl The check for libresolv is in case you are attempting to link statically |
