ANNOUNCE: DJGPP port of Cross-platform Audio Library (libao) 1.2.0 uploaded.

[Juan Manuel Guerrero (juan.guerrero@gmx.de) [via djgpp-announce@delorie.com]]

This is a port of Cross-platform Audio Library 1.2.0 to MSDOS/DJGPP.


Libao is a cross-platform audio library that allows programs to output
audio using a simple API on a wide variety of platforms. It currently
supports:
* Null output
* WAV files
* OSS (Open Sound System)
* ESD (ESounD or Enlightened Sound Daemon)
* ALSA (Advanced Linux Sound Architecture)
* PulseAudio (next generation GNOME sound server)
* AIX
* Solaris (untested)
* IRIX (untested)



DJGPP specific changes.
=======================

- The following backends are supported by the port:
file output: AU, RAW and WAV
live output: NULL

- The port expects "/dev/env/DJDIR/etc/libao.conf" as the system wide
config file and the user specific one either as ".libao" or "_libao"
in the HOME directory. If the HOME environment variable is not set
then the current working directory is used to find the config file.

- The reading/writing stream is switched into O_BINARY mode. If the
stream is connected to stdin/stdout/TTY, then Ctrl-C and Ctrl-Break
are re-enabled so the user can interrupt the program.

- Apart from those changes there are no other user visible ones. Only
some small changes have been done to get the library configured and
compiled.

- The Cross-platform Audio Library does not provide any test suite so
the port cannot be tested except by using it.

- To configure and compile this port at least the following version of
Bash, Make and pkg-config are required:
http://ftp.delorie.com/pub/djgpp/current/v2gnu/bsh4253b.zip
http://ftp.delorie.com/pub/djgpp/current/v2gnu/mak43br2.zip
http://ftp.delorie.com/pub/djgpp/current/v2tk/pkc023b.zip
No previous versions will work nor are supported. Any future version
should work.

- The port has been configured and compiled on WinXP SP3, Win98SE and
MSDOS 6.22 with DOSLFN v0.41f. There is no guarantee that this may
be possible with any other DOS-like OS. Due to the use of long file
names it will not be possible to configure and compile without LFN
support. The port has been compiled using gcc346 and bnu2351b.

As usual, all djgpp specific files (diffs, README files, etc.) are stored
in the "djgpp" directory. The sources have been configured to be build
in the "0build" directory. If for some reason it does not work for you,
delete its contents and configure from scratch again.

Please read the docs to become familiar with this product.
