compiling issues

Asked by maria ubiali on 2011-03-10

Hi,

I have a problem in generating a new process with MG5.
That's the error that I get if I try to generate a LO single-top and output a "singletop" folder

1) Generation looks OK

mg5>generate u g > d b~ t QED=2 QCD=1
INFO: Trying process: u g > d b~ t QED=2 QCD=1
INFO: Process has 4 diagrams
1 processes with 4 diagrams generated in 0.022 s

2) Here the issue in the compilation with the Makefile

mg5>output singletop
INFO: initialize a new directory: singletop
INFO: remove old information in singletop

for information about how to generate events from this process.
mg5>exit

Why does it report an error?

Here some info on my gfortran compiler

ubiali@lxte136:~/hep/Fabio/MA/MadGraph5_v0_6_2_3/singletop> gfortran --version
GNU Fortran (SUSE Linux) 4.5.0 20100604 [gcc-4_5-branch revision 160292]

and on python

ubiali@lxte136:~/hep/Fabio/MA/MadGraph5_v0_6_2_3/singletop> python --version
Python 2.6.5

Thanks for your help

Maria

Hello Maria,

The problem is when he tries to create a zipped version of the directory.

>tar: HTML: file changed as we read it
>make: *** [madevent.tar] Error 1

This is a quite common error of the "tar" command. So you don't have to worry about this warning.
Everything should be fine in your directory.

Cheers,

Olivier
