"make testprog" doesn't work

Asked by Ezequiel Alvarez

Hello,

I'm trying to introduce a user-model in MG5 but in the old fashion (using model_v4). I do everything as always, the "./ConversionScript.pl" script works OK, but when I put "make testprog" comes out the following. We have tried installing many packages, but we don't hit the correct one. If you got any idea we will be grateful. Thanks in advance, Ezequiel.

Hi,

its looks like that this might be a compiler issue. Could you try to install gfortran. and to change the compiler in the makefile.
Maybe this will works better. (Don't forget to remove all .o files before starting to re-compile)

Otherwise, could you send to us your model?

Cheers,

Olivier

Hello Ezequiel,

For the usrmod in MG5, the default Fortran compiler on the system is
used, which is apparently f77 on your system. This compiler is
deprecated, and gfortran is recommended. Please set the compiler to
gfortran, on a bash-type system you use
export FC=gfortran
before compiling. Please do "rm *.o" before the new compilation.

All the best,
Johan
