There are two ways to build this code;

(1) Manually

(2) Using all-singing all-dancing (all-confusing) autotools, ie. autoconf,

automake, and their little friends (autoheader, etc).

=================

Building Manually

=================

There is a basic "Makefile" in this directory that gets moved out of the way and

ignored when building with autoconf et al. This Makefile is suitable for

building tunala on Linux using gcc. Any other platform probably requires some

tweaking. Here are the various bits you might need to do if you want to build

this way and the default Makefile isn't sufficient;

* Compiler: Edit the "CC" definition in Makefile

* Headers, features: tunala.h controls what happens in the non-autoconf world.

  It, by default, assumes the system has *everything* (except autoconf's

  "config.h") so if a target system is missing something it must define the

  appropriate "NO_***" symbols in CFLAGS. These include;

  - NO_HAVE_UNISTD_H, NO_HAVE_FCNTL_H, NO_HAVE_LIMITS_H

    Indicates the compiling system doesn't have (or need) these header files.

  - NO_HAVE_STRSTR, NO_HAVE_STRTOUL

    Indicates the compiling system doesn't have these functions. Replacements

    are compiled and used in breakage.c

  - NO_HAVE_SELECT, NO_HAVE_SOCKET

    Pointless symbols - these indicate select() and/or socket() are missing in

    which case the program won't compile anyway.

  If you want to specify any of these, add them with "-D" prefixed to each in

  the CFLAGS definition in Makefile.

* Compilation flags: edit DEBUG_FLAGS and/or CFLAGS directly to control the

  flags passed to the compiler. This can also be used to change the degree of

  optimisation.

* Linker flags: some systems (eg. Solaris) require extra linker flags such as;

  -ldl, -lsocket, -lnsl, etc. If unsure, bring up the man page for whichever

  function is "undefined" when the linker fails - that usually indicates what

  you need to add. Make changes to the LINK_FLAGS symbol.

* Linker command: if a different linker syntax or even a different program is

  required to link, edit the linker line directly in the "tunala:" target

  definition - it currently assumes the "CC" (compiler) program is used to link.

======================

Building Automagically

======================

Automagic building is handled courtesy of autoconf, automake, etc. There are in

fact two steps required to build, and only the first has to be done on a system

with these tools installed (and if I was prepared to bloat out the CVS

repository, I could store these extra files, but I'm not).

First step: "autogunk.sh"

-------------------------

The "./autogunk.sh" script will call all the necessary autotool commands to

create missing files and run automake and autoconf. The result is that a

"./configure" script should be generated and a "Makefile.in" generated from the

supplied "Makefile.am". NB: This script also moves the "manual" Makefile (see

above) out of the way and calls it "Makefile.plain" - the "ungunk" script

reverses this to leave the directory it was previously.

Once "ungunk" has been run, the resulting directory should be able to build on

other systems without autoconf, automake, or libtool. Which is what the second

step describes;

Second step: "./configure"

--------------------------

The second step is to run the generated "./configure" script to create a

config.h header for your system and to generate a "Makefile" (generated from

"Makefile.in") tweaked to compile on your system. This is the standard sort of

thing you see in GNU packages, for example, and the standard tricks also work.

Eg. to override "configure"'s choice of compiler, set the CC environment

variable prior to running configure, eg.

    CC=gcc ./configure

would cause "gcc" to be used even if there is an otherwise preferable (to

autoconf) native compiler on your system.

After this run "make" and it should build the "tunala" executable.

Notes

-----

- Some versions of autoconf (or automake?) generate a Makefile syntax that gives

  trouble to some "make" programs on some systems (eg. OpenBSD). If this

  happens, either build 'Manually' (see above) or use "gmake" instead of "make".

  I don't like this either but like even less the idea of sifting into all the

  script magic crud that's involved.

- On a solaris system I tried, the "configure" script specified some broken

  compiler flags in the resulting Makefile that don't even get echoed to

  stdout/err when the error happens (evil!). If this happens, go into the

  generated Makefile, find the two affected targets ("%.o:" and "%.lo"), and

  remove the offending hidden option in the $(COMPILE) line all the sludge after

  the two first lines of script (ie. after the "echo" and the "COMPILE" lines).

  NB: This will probably only function if "--disable-shared" was used, otherwise

  who knows what would result ...
