Hi,
I was trying to install SUMO for veins, and if I run the macports command "sudo port install sumo", it gives me an error saying cctools failed to install. I have already tried sudo port clean cctools, sudo port install cctools, and sudo port -f activate cctools, but none of them work. I also tried downloading the sumo-0.12.2-src.tar.gz file and unpacking it and running ./configure, but that gives me an error saying xerces-lib not found, even though xercesc is installed. Does anyone know how to solve this? Thank you so much!
