thanks, wiping the old hal.so in /usr/lib/python* made all the difference.
One remaining problem and I guess we're off to the races. I have:
[DISPLAY]
EMBED_TAB_NAME = gladevcp-test
EMBED_TAB_COMMAND = gladevcp -c gladevcp-test -w {XID} gladevcp-test.ui
gladevcp window comes up fine in Axis tab, gladevcp-test hal module in place,
pins in place so I think I go about linking the hal pins for the example
I take your gladevcp-test.hal, comment out the loadusr statement at the top and
add to .ini
[HAL]
POSTGUI_HALFILE = gladevcp-test.hal
during startup I get
gladevcp-test.hal:5: Pin 'gladevcp-test.hal_button1' does not exist
However, if I drop the .hal file from .ini and manually enter the statements
from gladevcp-test.hal they work fine
this looks like a race condition to me - the POSTGUI_HALFILE is run before
gladevcp had time to setup the hal component
this one and we're done ;-)
thanks in advance,
