dear Readers,
wxGUI-sinks seems to be brocken under following circumstances:
GnuRadio on 192.168.1.10 (Opensuse 11.4)
xterminal on 192.168.1.11 (Opensuse 11.4)
- connect from x.x.x.11 to x.x.x.10 via ssh -X 192.x.x.10
- $ gnuradio-companion --> (everything shows fine)
- run test.grc with a wxGUI- Scope
new grc-file:
test grc has: generator— throttle — wxGUI-Scope
after short initial startup message of the compiled top_block.py
a) on the Gnuradio-Worstation x.x.x.10: everything works fine:
scope-window opens and show the expected result
b) on the xterminal station x.x.x.11 there is no scope-window opening. a
short message in the still open GR-message window simply shows
“>>> Done”
(no further error messages)
c) if i use older LINUX-Installations LINUX MINT8 or Suse 11.0 or
windows XMing as xterminal-station (e.g. x.x.x.11 similar) it works like
case a) : scope-window is showing up, everything as expected
QT GUI Widgets (scope) work fine under any circumstances
it seems to be independent of the gnuradio version since 3.3 (I tried
3.3, 3.4, 3.5, which I compiled for Opensuse and Ubuntu and Linux Mint 7
and 8) As I remember: it was working before with any combination at that
time.
Since there are many changes in between on the system-versions and the
Gnuradio-Versions I do not know how to catch it.
looking arround in the net gives no answer until now.
I feel, it has something to do with the wxGUI and the combination of the
xserver. (Some times ago there were under special circumstances error
messages showing Xlib-errors)
now i use gtk (v 2.8.) X11: (v7.6) opensuse 11.4, GnuRadio 3.5.0
(compiled by myself)
any recommendations to catch the error?
thanks in advance
M. Hartje
