Question about running madevent on cygwin

Asked by John

I am trying to run madevent on windows through cygwin.
When I execute generate events file, this error pops out,

touch: cannot touch `files/madevents/RunWeb': No such file or directory
     15 [main] python2.6 3536 child_info_fork::abort: address space needed by 'fcntl.dll' (0x360000) is already occupied
Traceback (most recent call last):
  File "./generate_events", line 104, in <module>
    launch = ME.MadEventCmd(me_dir=root_path)
  File "/cygdrive/c/program files/madevents/bin/internal/madevent_interface.py", line 1334, in __init__
    misc.Popen([pjoin(self.dirbin, 'gen_cardhtml-pl')], cwd=me_dir)

  File "/usr/lib/python2.6/subprocess.py", line 1051, in _execute_child
    self.pid = os.fork()
OSError: [Errno 11] Resource temporarily unavailable

For run card.dat file, this message appears

./run_card.dat: line 23: tag_1: command not found
./run_card.dat: line 27: .false.: command not found
./run_card.dat: line 33: 10000: command not found
./run_card.dat: line 34: syntax error near unexpected token `('
./run_card.dat: line 34: ` 0 = iseed ! rnd seed (0=assigned automatically=default))'

How can I solve this program? (Note that I installed python from cygwin.)

Hello John,

You are probably the first person to try running MadGraph on cygwin. It seems that the problem here might be due to Python (since the path reported is files/madevents/RunWeb, but paths under Windows should be with backslash instead of forward-slash). Most probably, even if these particular issues are fixed, there would be an infinite (or at least very large) number of new issues popping up later. So, unless you want to take on the task to make MadGraph work under cygwin, I would suggest to simply install Linux (as separate boot or in a virtual box) and run MadGraph from there instead.

All the best,
Johan

Hi john,

You are not the first one to try to use cygwin. But as said by Johan, they all finally installed Linux in either a virtual machine and/or in dual boot.

Cheers,

Olivier
