Hi Josh,

Thanks a lot for your feedback.
looks like that code is just not compiled anymore ( I still have to investigate where to add such compilation)
The reason why this is not compile is actually simple since I have replace this script by a python script for “normal” run.

One simple fix is to go inside the Source directory of the gridpack and run 
make ../bin/internal/gen_ximprove

Now the generation of the events works but I have the following error:

Running addmasses.py to add masses and correct kinematics of fixed particles
Traceback (most recent call last):
 File "./madevent/bin/internal/addmasses.py", line 172, in <module>
   for l in s.split(): t.append(parseStringToVars(l))
 File "./madevent/bin/internal/addmasses.py", line 100, in parseStringToVars
   return int(input)
ValueError: invalid literal for int() with base 10: ‘<mgrwt>'

The <mgrwt> is a SysCalc block information. 
Do you use this add masses.py script? or do you use your own anyway?
Does it still makes sense to distribute it within MG?

Cheers,

Olivier


Looks like the add masses script do not support the SysCalc information.
