Hi Andrew,
With the FC1 AccessGrid-2.3-5.i386.rpm and AccessGrid-2.3-6.i386.rpm, I
forgot to increase the version number in
AudioService.svc (located in AudioService.zip), if it's not increased, then
the contents of the following
folder don't get replaced with a newer version of rat:
~/.AccessGrid/local_services/AudioService
[I did remeber to increase the version number with the FC2 AudioService.zip]
So, you could do the following (but make sure AGServiceManager.py is not
running) :
rm -rf ~/.AccessGrid/local_services/AudioService
Restart the ServiceManager and a new AudioService will get unpacked the
first time AudioService is used.
The rat that comes with AccessGrid-2.3-5 and later was rebuilt with
gcc-2.9.6 (instead of gcc 3.x), which seemed to fix the problem of the rat
GUI not coming up in some situations. Also rat now has alsa lib statically
linked, so I could remove the alsa-lib RPM dependency.
Recently Steve Smith cleaned up and fixed some of the rat souce code (see
"Big Linux fixup patch" thread in ag-tech mailing list). I've rebuilt rat
with Steve's patches, if you want to try it, download:
http://www.itee.uq.edu.au/~agn/ag_fedora/FC1/stable/patches/AudioService.zip
to replace:
/etc/AccessGrid/NodeServices/AudioService.zip
It should automatically get unpacked as I've increased the version number in
AudioService.svc.
