Launching madevent

Hi John,

gfortran is all what you need in order to compile (with gmake if this is not install by default --like on Mac)

By googling on the web your compilation error, I have find the following link:
https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/738098
or this one
http://stackoverflow.com/questions/6329887/compiling-problems-cannot-find-crt1-o

They contains multiple suggestions on how resolve such error.

Cheers,

Olivier

Hi Olivier

After making the library link as the two links suggested in your reply, I still get the same error message.

I heard that there needs to be a make file in the madgraph directory to solve this problem. And it looks like there isn't.

Please note that I am using the Red-Hat linux and the gfortran complier, 32-bit processor (i686) downloaded from

http://gcc.gnu.org/wiki/GFortranBinaries#GNU.2BAC8-Linux

Please let me know if I am using a wrong file.

Could you explain more what you mean here?
The path of the makefile in this case is
./Source/makefile
and in your crashing case it's call like:
cd Source
make ../bin/internal/gen_ximprove

Did other (f77) program compiles correctly?

Did your computer is 32 bit?
If not could you try to install the 64 bit version?
(both link seems to indicate a 32-64 bit mismatch)

Cheers,
