-INSTALLATION INSTRUCTIONS for ADNS
+INSTALLATION INSTRUCTIONS for GNU ADNS
1. Read the security note below.
2. Standard GNU package build process:
- $ ./configure
+ $ ./configure [--disable-dynamic] [--prefix=... ...]
$ make
# make install
-Unfortunately, since this is a beta, there is no good documentation
-yet. For now, use the comments in the public header file adns.h.
+Unfortunately, there is no comprehensive documentation yet. For now,
+use the comments in the public header file adns.h, and for the C
+programs their usage messages. If you find this information
+ambiguous, incomplete or wrong, please report it as a bug.
-You will find that adns requires a reasonably standard and up to date
-system.
+TESTED PLATFORMS
The following platforms have been tested at at least some point and
should work - please report if they don't:
- [adns] OS
- 1.0 Linux glibc 2.1 (actually tested on Debian 2.2).
-
- 1.0 Solaris 2.6, 2.7, 2.8
+ adns version OS
+ 1.0 Linux glibc 2.1 (actually tested on Debian 2.2)
+ 1.0 Solaris 2.6, 2.7, 2.8 [3]
1.0 FreeBSD 3.2, 4.0 (no poll(2), so no adnsresfilter)
-These appear to work, but only with --disable-dynamic:
+The following work, but only with --disable-dynamic:
1.0 IRIX 6.5 *not* with GCC [1], [2]
1.0 AIX 4.1.5
1.0 HP-UX 10.20, 11.00
+ 1.1 Darwin (kernel 7.5.1)
+Later versions of the same OS should work too. Usually entries in
+this table mean adns passes its own regression test, when compiled
+with GCC, and appears to install and run correctly. If you have more
+information for this table please let me know.
-Later versions of the same OS should work too. [adns] is the latest
-version of adns that has been tested. Usually entries in this table
-mean they pass adns's own regression test, when compiled with GCC,
-and appear to install and run correctly. Notes/known problems:
- [1] IRIX 6.5 inet_ntoa seems to break with GCC.
- [2] Many spurious warnings from this platform's native compiler.

+ [2] The SGI IRIX compiler produces many spurious warnings.
+ [3] Dynamically linked, needs some help to find libadns.so.1.0.
The following platforms are known to be deficient and will not work:
- Solaris 2.5 Lacks vsnprintf - install glibc ?
- TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf - install glibc ?
+ Solaris 2.5 Lacks vsnprintf - install glibc ?
+ TruUnix64 (DEC UNIX 4.0f) Lacks vsnprintf - install glibc ?
Please don't report these problems unless you have a nice,
-straightforward solution or workaround for them.

+
+PORTABILITY INFORMATION
+
+You will find that adns requires a reasonably standard and up to date
+system. Systems which are neither GNU nor UNIX are not supported.
+
+The build system assumes by default that you have ELF shared
+libraries, and that the directory in which libadns.so.1 will be
+installed is on your dynamic library search path. If your system
+doesn't have ELF shared libraries then dynamic linking is not
+supported by adns. Use the --disable-shared configure option.
+Please don't send me patches to use libtool (which I dislike).
-In particular, the build system assumes that you have ELF shared
-libraries. If you don't then please don't send me patches to support
-your kind of shared libraries, and don't send me patches to use
-libtool. I'm not interested in supporting non-ELF shared libraries,
-and I dislike libtool. If you do not have ELF shared libraries then
-please use the --disable-shared configure option.
+Compilers other than GNU C should work, but are not well-tested. Feel
+free to send me patches to improve the situation. However, the
+Makefiles only know how to use GCC to make dynamic libraries.
The adnsresfilter utility uses `tsearch' from the C library (a la SVID
-and X/Open). If your C library doesn't have tsearch you will find
-that configure arranges for adnsresfilter not to be built. To rectify
-this, install a C library containing tsearch, such as the GNU C
-library. It is best if tsearch uses an automatically-balancing tree
-algorithm, like the glibc version does. Simple binary trees may
-perform badly.

+If you change the m4 input files in regress/ you may need GNU m4.
You will probably find that GNU Make is required.
+Please do not report this as a bug; install GNU Make instead.
SECURITY AND PERFORMANCE - AN IMPORTANT NOTE
-adns is not a full-service resolver. It does no caching of responses
+adns is not a `full-service resolver': it does no caching of responses
at all, and has no defence against bad nameservers or fake packets
which appear to come from your real nameservers. It relies on the
full-service resolvers listed in resolv.conf to handle these tasks.
