[Linrad] Linrad-02.45 ALSA/4Front

[Leif Asbrink <sm5bsz.com; leif@xxxxxxxxxxxxxxxx>]

Hi All,

The latest version, linrad-02.45, differs from 02-44 in
the setup for its rx input while the dsp processing is not
changed.

There are a couple of bugs detected already. They are
related to ALSA. As far as I know there is no bug detected
with the Windows version yet.

On a system where ALSA has never been installed, the setup
does not work. Use 02-44 or change lconf.h to define
ALSA_PRESENT (even though it is not.) Do not run configure 
again (would erase your change of lconf.h) Answer N to 
"use native ALSA?" in the setup.

SDR-14 or SDR-IQ can not be selected. Use 02.44.

The configure script tries to determine whether a system
uses OSS/4Front or ALSA. I did this by looking for 
the file  /usr/lib/libasound.so but that was not a good 
idea:-( 

When I install OSS, the  /usr/lib/libasound.so is not removed
so Linrad falsely believes that ALSA is installed.
Is there anyone on this list who knows how I should find
out if ALSA is installed and working? The current code is:

AC_CHECK_FILE( /usr/lib/libasound.so, ALSAN="1")
AC_SUBST(ALSAN)

What would be better? libasound.so is not removed by 
the OSS installer.....
