Code: [Select]
/usr/bin/scm-load: line 41: can't open /etc/sysconfig/icons: no such fileIs this a known and common issue as it was also observed today when downloading Links2?

Do you have wbar.tcz loaded?  Not doing so will result in that error.

Also, do you have the latest audacity-1.3.scm?  It works here, both icon, menu, and command line.

None of the systems I build use wbar.  It is unlikely that I am alone in this based upon it regularly being raised in the forum.  My understanding is that wbar is now a separate and optional package.  Is this incorrect?



Also, do you have the latest audacity-1.3.scm?  It works here, both icon, menu, and command line.
Scm browser reports v1.3.  No pending updates.  Symptoms remain unchanged.
Code: [Select]
/apps/audacity-1.3/bin/audacity-1.3
/audacity-1.3-bin: error while loading shared libraries: libtiff.so.3: cannot open shared object file: No such file or directory

Separately installing and loading graphics-lib-1.tcz allows Audacity to start.
   
A thought...
This test rig is using OSS.  Is yours using ALSA?  If so is graphics-lib-1 a dependency of one of the installed ALSA packages?

I am using OSS a bit with the scm's, and I try to build with support for both alsa and OSS when possible, and so far that has been possible.

I added the tiff dependency, as I use Icewm that is already installed via tcz's so I did not notice.  Thanks for finding.

I have found wav files problematic in other apps as well, but I will check it out with audacity tonight.

It seems audacity tries to use ffmpeg to function with wav files.  I have a build script to create a static ffmpeg, I will build it and plug it in the extension soon.  But for now, installing ffmpeg-ffserver will work.

I added a shared build of ffmpeg version 0.7.11, as audacity looks for libavcodec.so.52 for ffmpeg functionality.  If one imports wavs that show up when searching for ffmpeg compatible files, they should work.

I'm not certain what is meant by this. 

Successfully tested the import and export of various formats mp3, flac, wma...  All work OK.

The problems with wav files are still present.  Importing closes Audacity, exporting generates the previously mentioned error message.

To see if they might be related to the version of Audacity on which the scm is based, I tried v2.0.0 from the Debian 6 testing repo in another distro.  Note, this is not identified as beta.  All worked OK including the import/export of wav files.  Might it be worth looking at the newer release?

Audacity uses libavcodec from ffmpeg to deal with things like a wav. 

But I will look into a rebuild and an update to 2.0 to see if that will fix it.  Actually building against ffmpeg instead of just plugging it in, though the libavcodec library is still recognized, may make things better.

After many rebuild tweaks and updating to 2.0, I found that alsa must be used as the sound system when dealing with wavs in audacity.

I have built a 2.0 version that I will upload shortly, but the 1.3 version works with wavs if alsa is used as the sound system.
