Re: [sumo-user] Previous stage output not available in TraCI

Hello Dillip,

there must be another error in the output of the makefile.

If you run step 5 without the -j option (just sudo make), the other error should be at the end too.

Greetings, Harald

Hello Jakob,
Thank you for taking so much of effort to correct the null pointer.

I downloaded the latest version of August 5 and followed the following steps for installing SUMO on my Ubuntu 18.04 machine.

  1. sudo apt-get install cmake python g++ libxerces-c-dev libfox-1.6-dev libgdal-dev libproj-dev libgl2ps-dev swig

  2. export SUMO_HOME="$PWD/sumo"

  3. sudo mkdir sumo/build/cmake-build && cd sumo/build/cmake-build

  4. sudo cmake ../..

  5. sudo make -j$(grep -c ^processor /proc/cpuinfo)

  6. sudo make install

However,Step-5 resulted in the following error while installation:
[  2%] Linking CXX static library libutils_xml.a [  2%] Built target utils_xml Makefile:140: recipe for target 'all' failed make: *** [all] Error 2
Kindly look into the issue.
with best regards,
Dillip Rout

Please try again with the latest development version tomorrow (https://github.com/eclipse/sumo/issues/7336).

Finally, I installed SUMO through the command line (sudo apt install SUMO) and tried to get the previous stage data through TraCI but again the same issues persist here, i.e., it goes for exception and the program stops.
It is a prolonged question which is yet to be answered by anyone, will I get an answer for it?

Again, accessing previous stage data leads to error when I tried with the latest development version which was updated on July 9.

Hello,

I had raised this question long time ago that the TraCI program is unable to find the  previous stage information incase the current stage has been completed successfully. Particularly I was trying to extract the following information from the previous stage.

         print("previous stage","type",prevStage.type,"dest",prevStage.destStop,"travel time", prevStage.travelTime, "distance",prevStage.length,"depart  time", prevStage.depart)

Unfortunately, the output does not contain all the required information, as shown below.
         previous stage type 3 dest busStop#12 travel time -1.0 distance 672.437702712895 depart time -0.001

@Jakob replied: that information was previously missing from the stage output (https://github.com/eclipse/sumo/issues/7274). You can download the updated version tomorrow and find out the desired result.

Surprisingly, when I tried to execute the TraCI code (demo-i.py) after installing the latest version (updated on July 5),  I got some exceptions now which were not there in the previous versions. In particular I am getting the following error:
          Error in Previous Stage retrieval, so, skip this personID:  2229
         , which is due to line number 97 in my TraCI program.

Kindly check the issues in the development version and suggest to me. I am enclosing the network and corresponding codes for tracing the issue.

regards,
Dillip Rout
