Hi Harald, hi Jakob,
I tried to do what Harald recommended. (took me some time, as I faced a few
problems on my way, but now almost all are solved)
The last step in which I am supposed to do:
gdb --args sumoD -c debug.sumocfg
gives me back:
sumoD: No such file or directory.
even if sumoD exists...
To double-check I tried in the terminal:
weronika@MBP-Weronika ~ % sumo-gui
(this worked)
weronika@MBP-Weronika ~ % sumo-guiD
zsh: command not found: sumo-guiD
Do you know what could I try to solve it?
Today I wanted also to try what Jakub recommended.
My traci.start is:
traci.start([sumoBinary, "-c", '../' + selectedFolder + '/osm.sumocfg',
"--tripinfo-output", '../' + selectedFolder +
'/out/tripinfo.out.xml',
"--summary-output", '../' + selectedFolder +
'/out/summary.out.xml',
"--netstate-dump", '../' + selectedFolder +
'/out/netstate.out.xml',
"--vehroute-output", '../' + selectedFolder + '/out/route.out.xml',
"--duration-log.statistics", "true",
"--log", '../' + selectedFolder + '/out/log.txt',
traceFile="traci.log",
"--vehroute-output.route-length", "true"])
Adding it directly like this doesnt work, as it is invalid syntax I
will need to adapt it to my traci.start... (I tried a few
modification, but without any success) Could you please help my with
how to do it?
Thank you for your support
best,
Weronika
