  • Installing ALSA libraries

    From bob prohaska@3:770/3 to All on Sat May 8 01:22:36 2021
    Since the package for xoscope doesn't include ALSA support I
    tried downloading the latest sources. Looks like that doesn't
    find the required ALSA libraries, if I understand the instructions
    for compiling correctly. There doesn't seem to be a configure option
    for ALSA support, instead configure looks for libraries and builds
    for what it finds. At this point configure reports, in part:

    ALSA module: no
    COMEDI module: no


    An apt search for ALSA turns up lots of applications that use it,
    but I don't recognize a generic installation target. What am I
    missing?

    Thanks for reading

    libasound* works for *most* alsa. When I was playing with it I needed
    something else, but that *may* not have been alsa related...

    don't know what you mean by most - this is the alsa library headers needed
    for compiling with alsa support

    for comedy it is self explaining

    libcomedi-dev - Development library for Comedi

    however there is possibility that a specific version is required and the autotools system still does not find what it is configured to look for.
    You have then the option to look into the autotools config files and solve
    the dependencies in detail.

    you should post relevant parts of the error output so we can see what it
    failed to find and/or what other errors are related

    That was the confusing part. There were no errors of any kind reported.

    Both libasound2-dev and libcomedi-dev are available and installed without problems. The configure script reported finding both of them and
    make completed without complaint.

    The resulting binary runs and displays in a reasonable fashion. It
    seems that ALSA works somewhat better, in the sense of giving a
    recognizable disply to a squarewave input more easily. It's possible
    to switch to COMEDI device mode, but the display seems unresponsive.
    Since I'm dealing with a sound capture device that's not very strange.

    Thanks very much for everyone's help!
