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 On Mon, 3 Aug 2020 at 19:19, Jakob Erdmann <namdre.s...@gmail.com> wrote: > Please try again with the latest development version tomorrow ( > https://github.com/eclipse/sumo/issues/7336). > > Am Mi., 22.
