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 installcmake python g++ libxerces-c-dev
libfox-1.6-dev libgdal-dev libproj-dev libgl2ps-dev swig
2.
exportSUMO_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

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

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
