Wrong YARP_PORT_PREFIX in yarpmanager

[Tobias-Fischer]

Hi, currently the YARP_PORT_PREFIX=;, which breaks some applications (e.g. our robot didn't start using yarprobotinterface - not sure whether this is related or some other issue with our robot).
This is due to https://github.com/robotology/yarp/blob/master/src/libYARP_manager/src/manager.cpp#L292 which was introduced in 238bf63

YARP_PORT_PREFIX=; is the same as the previous (i.e., YARP_PORT_PREFIX=) in the yarpmanager (theoretically should be the same).

@Tobias-Fischer would you provide more information on "it breaks some applications"?

• Dose the manager run your modules?
• What is the output of yarp name list after launching the application/modules?
• With which particular module you faced this problem?

Hi,

• Yes the manager does run modules
• With the ; symbol, for instance when running yarprobotinterface, the port for the analogServer is wrong: yarp: Port ;/icub/left_hand/analog:o/rpc:i active at tcp://10.0.2.2:10065 which is then leading to ERROR AnalogServer Error initializing YARP ports and yarpdev: ***ERROR*** driver <analogServer> was found but could not open
• When removing the ; yarprobotinterface is starting nicely

I guess your YARP is not updated on the machine (e.g. PC104) where you are running yarprobotinterface. The 238bf63 also modified yarprun.!!!

Anyway, I just changed the yarp manager library to double check the port prefix and environment variables to avoid unnecessary ";".
See pull request #982

@maxime-petit would you please update your YARP on PC104 and let me know?

Hi @apaikan,
We got rid of this error on all of our Linux machines after updating, however our Windows machine still suffers from the ";" in front of the port names. We use the Windows machine mainly for speechRecognizer, but I guess the problem is independent of that. Could you please have a look whether it's working on your Windows machines?

Thanks,
Tobias

Hi
@Tobias-Fischer Do you still getting ';' in front of the ports prefix in Windows?
I have just checked it on my windows machine (devel branch) and everything look good.
Would you check it again (e.g. with EyesViewer-Localhost from yarpmanager) and let me know ?

[Tobias-Fischer]

Hi @apaikan,
I completely re-installed yarp on the Windows machine, and I think it's all good now. Thanks and sorry for the confusion.

Best, Tobi
