  Hello folks!


This is libmikmod, version 3.2.0-beta1, a portable sound library for Unix
and other systems. Check out the file 'NEWS' for more history information.


>> BETA WARNING
---------------

This is a *beta* version of libmikmod. Although it should work fine on
almost all systems, there are likely a few last-minute errors or typos
in the source, and some parts have not received enough hours of testing yet.

Also, please note that all features planned for the final 3.2.0 release are not
available yet. Some structures or functions may change. This release is mainly
intended to the libmikmod developers to share a common base for adding new
features...

The library programming documentation (in docs/) is mostly up-to-date... It
lacks the Player_QueryVoices documentation, though.

If you're not scared, then you can proceed and enjoy fewer bugs than in the
previous version (-;


>> BUILDING LIBMIKMOD
---------------------

- If you're building libmikmod under MacOS, please refer to the 'README'
  file located in the 'macintosh' subdirectory.

- If you're building libmikmod under OS/2, please refer to the 'README'
  file located in the 'os2' subdirectory.

- If you're building libmikmod under Windows, please refer to the
  'README' file located in the 'win32' subdirectory.

- If you're building libmikmod under any other system which is not a
  Unix flavour, then be warned that this your platform is not supported
  and that libmikmod will probably not build out of the box; don't
  hesitate to drop me a note, and I'll see what I can do for this situation.

So you're on a good old Unix workstation, aren't you ?

You'll need an ANSI C compiler to build libmikmod. If your system does not
come with an ANSI C compiler, you might want to try the GUN C compiler, gcc.
If you're building on a 32 bit architecture, your compiler must provide a
64 bit integer type (usually 'long long').

To prevent clobbering the sources, I recommend building libmikmod in an
alternate directory, for example 'build':

  mkdir build
  cd build

In this directory, run libmikmod's configure script:

  ../configure

The configure script will attempt to guess correct values for various
system-dependent variables used during the build process, and will
create appropriate Makefiles for proper compilation.

If you're not familiar with configure scripts and their standard
options, you can find more general information about them in the file
INSTALL.

The default behaviour of the configure script is to create both a static
and a shared library, with as many drivers as possible, which are
dynamically loaded whenever possible. However, it can be given several
options to tweak your configuration of libmikmod:

The --enable-af, --enable-alsa, --enable-esd, --enable-oss,
--enable-sam9407 and --enable-ultra options will compile respectively
the Digital AudioFile, Advanced Linux Sound Architecture (ALSA),
Enlightened Sound Daemon, Open Sound System (OSS), sam9407 and Linux
Ultrasound drivers.

Since the configure script will search for the appropriate include files
and libraries, to compile as much drivers as possible, these options are
mostly useful in their negative form:
  ../configure --disable-esd
will configure libmikmod without the Enlightened Sound Daemon driver,
even if all the necessary files for compiling are present on the
system.

The --enable-dl option enables the dynamic load of the alsa, esd and
ultra drivers at runtime, if your systems support it. This option is
enabled by default if the build system supports it, so it is more useful
in its negative form:
  ../configure --disable-dl
will configure libmikmod without the dynamic loading facility.

The --enable-threads option enables the creation of a thread-safe
libmikmod library, if your system provides POSIX threads. This option is
enabled by default, so it is more useful in its negative form:
  ../configure --disable-threads
will configure for a non thread-safe version of libmikmod.

The --enable-shared and --enable-static options control whether a static
library, a shared library or both should be built.

The --enable-debug option creates a debug version of libmikmod.

After you've successfully run configure, simply run

  make

to get all things build. Then, run

  make install

to have the library installed. Depending on where you choose to install
it (using the --prefix= option to configure), you may need root
privileges for this operation.

>> ALSA DRIVER SPECIFIC INFORMATION (Linux specific)
-----------------------------------

The Advanced Linux Sound Architecture (ALSA) project aims to provide
better sound facilities than the current OSS drivers. Although it is
still in beta, it appears to be very stable and very easy to program
compared to the OSS.
Besides, it works much better than OSS for Gravis-type soundcards.
