Madgraph5 no madevent ouptput

Dear Michael,

Which version of MG5 are you using? What was the full procedure that you used? Did you copy the Template directory to a new directory and work in this directory? Or did you reuse an existing process directory?

Thanks,
Johan

Hi Michael,

You are lucky, I just face this problem today on my computer (due that I reinstall completely my Mac Os system)
The problem is that gcc is not install on your computer.
The easiest way to install gcc on your computer is to install xcode that you can download on the mac website.

http://developer.apple.com/xcode/
(Note that xcode4 is not free but you can download xcode3 for free (the link is at the bottom right of the page)

Cheers,

Olivier

PS: I agree that the error is not clear, but that's the error raise by the shell when you type 'make'.

Hi Johan,

I am using the latest MG5 that I just downloaded (to reinstall). I
used a previous (existing) working directory that I copied into the
new Madgraph5 directory. However, I get the same problem when I try a
very simple sm process from the command line interface.

Before I upgraded to OS 10.6, this was all running without a problem,
using python 2.7.

Thanks for your help on this.
Michael

HI again,

Here is the MG5_Debug output, in case it helps.

Thanks

Just to add that for mac os 10.5 user. xcode is available here:
https://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/getSoftware?bundleID=20414

This is a compilation problem. -> this is solved

Dear Michael,

What happens if you run "make" by hand in a terminal? It seems from the error description as if there is no such command.

Best,
Johan

Hi Johan
Correct, there is no make command (i tried). There was no makefile in
the MG5 version I downloaded. Should there have been?

THanks,
Michael

Hi Johan,

The problem is solved. For your future reference, the issue is: when I upgraded to 10.6 the links to my old gcc were lost so it
could not compile. I installed Xcode3 again and it is now running fine.

Thanks for the help,
Michael

Hi Olivier,
I re-installed Xcode3 and things now work fine as you suggested. it seems that upgrading to 10.6 caused a loss of links to my old compiler.

Thanks for the help,
Michael
