OSM Web Wizard error in generating scenario #15253

Open magni5 opened 4 months ago

magni5 commented 4 months ago

First of all, thank you for your work.

My situation is the following.

SUMO-version: 1.20.0 operating system: Fedora Linux 40

I have downloaded SUMO from FlatHub. From the file system location of the application I have run python osmWebWizard.py. Using the browser (tried both from Firefox and Brave) I have tried to Generate Scenario (both with default and custom configuration, even with less "resources" as possible). The generation starts but then it gives error. Below the output from the terminal.

Cannot create directory '/var/lib/flatpak/app/org.eclipse.sumo/x86_64/stable/17548b556b3903938ed1f4b8d2cda926484e7bbb21f0b2fce409a99b4b2d0039/files/share/sumo/tools/2024-07-22-12-39-47'.

In the folder /home/marco/Sumo/2024-07-22-12-39-47 is generated only a osm_bbox.osm.xml.gz file, but when uploaded to SUMO it gives Error: No option with the name 'tag' exists.

osm_bbox.osm.xml.gz is the downloaded OSM file which still needs to be converted to a SUMO network file. In your case this process fails because libgdal / GDAL library cannot be found.

The problem is that calling executables from inside the flatpak is not that easy. I tried to do flatpak run --command=bash org.eclipse.sumo. I can at least run netconvert then. But if I run the webWizard inside that bash, my browser refuses to connect to the index.html. The same thing happens if I start the web wizard from the flatpak directly. Can you recheck whether the bask workaround helps in your case?
