  • ANNOUNCE: DJGPP port of Cross-platform Audio Library (libao) 1.2.0 uplo

    From [via djgpp-announce@delorie.com]" <@21:1/5 to All on Sat Dec 31 18:18:38 2022
    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.
