CutTools not compiling for NLO processes in fresh checkout of 2.6.3.2

[James Howarth]

Hi Everyone,

I downloaded a fresh version of MG5_aMC 2.6.3.2 in a fresh terminal (Mac Sierra 10.12.2) and installed a number of additional packages using the interactive prompt:

> install pythia8 (also prompts a lot of installing)
> install ninja
> install collier

and then try to generate a new process and output it:

> generate p p > t t~ z [QCD]
> output NLO_TTZ

at this point it tells me that it is compiling cuttools and crashes (see below).

I've seen this same bug in 2.6.2 and 2.6.1, and it occurs if I go into vendors and try to recompile it by hand. I also checked on an lxplus setup and encounter the same problems.

The version I have of gfortran on my mac is:

GNU Fortran (Homebrew GCC 8.1.0) 8.1.0

and on lxplus is:

GNU Fortran (GCC) 4.9.3

Any help you could provide with fixing these compilation errors would be greatly appreciated!

Cheers,

Jay

Hi,

The problem that you report is linked to GCC8.
Sounds weird that you face the exact same error on gcc4.9.3 (but if you setup gcc via a environment variable to turn warning into crash).

Not sure what we can do concerning Cuttools and the compatibility with gcc8.
I will assign Valentin to comment on this.

Cheers,

Olivier
