Re: [sumo-dev] Lead vehicle type in Wiedemann car-following model
You need a working installation of python and then the version.h file is automatically generated during the build process.

Thanks. I have downloaded it from github.

However, when I build it I get an error:  Cannot open include file: 'version.h': No such file or directory  

So, I opened an github issue:  Error: Cannot open include file: 'version.h': No such file or directory #3967 on sumo master.

the files at http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version are only updated during the night. If you download tomorrow you should be able to get them there.
Alternatively, download them directly from github: https://github.com/DLR-TS/sumo/archive/master.zip

Hi Jakob,

Thanks for your reply. I see that you made changes few hours ago.  I'm very new to git/github and developement so please bear with me. 

Based on the commit ID you provided, I found that the changes are shown on this URL: https://github.com/DLR-TS/sumo/commit/8f43c4a6874690c0a41443b1efbead0e4384f921  

So, I thought when I download the development version from this link: (http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version)  I'd get the new files

However, I don't see any changes in the files. Where can I download the latest development version that includes those followSpeed() changes that you recently made?

Hello,
in the very latest development version (8f43c4a6874690c0a41443b1efbead0e4384f921) the followSpeed() API includes a parameter for the lead vehicle. Note, that in some calling contexts, this value may be a nullpointer

Hi,

I am looking into the Wiedemann model and related
​.​
cpp and .h files in the development version of SUMO.   

Is there a way to print or do something with the LEAD vehicle type in the MSCFModel_Wiedemann.cpp?. I found 'gap2pred' and 'predspeed' but nothing like 'predType' or 'predClass'.

Ideally, I want to change the behavior of following vehicle if the lead vehicle class is a truck.
