installation of pythia-pgs fails

[stefano de nicola]

While installing pythia-psg from mg5, i get the following error message:

gfortran -fno-automatic -o examples/olympics examples/pgs_olympics.f \
            -L./lib -lpgslib -ltauola \
            -lstdhep -lexthep -lFmcfio -L../../libraries/pylib/lib -lpythiaext; chmod +x examples/olympics
/usr/bin/ld: cannot find -lpythiaext
collect2: error: ld returned 1 exit status
chmod: cannot access `examples/olympics': No such file or directory
make[2]: *** [examples/olympics] Error 1
make[2]: Leaving directory `/afs/cern.ch/user/s/sdenicol/MadGraph5_v1_5_11/pythia-pgs/libraries/PGS4'

make[1]: Leaving directory `/afs/cern.ch/user/s/sdenicol/MadGraph5_v1_5_11/pythia-pgs/src'
make: *** [all] Error 2

After looking at other (seemingly unresolved) posts on similar problems, I have updated Python, Root and gcc to the latest versions and I have tried changing 64 bits to 32 (even if my sistem si 64) in pythia-pgs/src/make_opts .
Neither of these attempts seem to produce any changes.
Please let me know if there is a way around this...

Hi,

I have the same issue: I have made a fresh installation of the recent version of MadGraph5, v1.5.11, and when I want to install pythia-pgs in mg5, I get the error

----- Now compiling examples/olympics -----

gfortran -fno-automatic -o examples/olympics examples/pgs_olympics.f \
            -L./lib -lpgslib -ltauola \
            -lstdhep -lexthep -lFmcfio -L../../libraries/pylib/lib -lpythiaext; chmod +x examples/olympics
/usr/bin/ld: cannot find -lpythiaext
collect2: error: ld returned 1 exit status
chmod: cannot access ‘examples/olympics’: No such file or directory
make[2]: *** [examples/olympics] Error 1
make[2]: Leaving directory `/home/ivana/MadGraph5_v1_5_11/pythia-pgs/libraries/PGS4'
make[1]: *** [../libraries/PGS4/examples/olympics] Error 2
make[1]: Leaving directory `/home/ivana/MadGraph5_v1_5_11/pythia-pgs/src'
make: *** [all] Error 2

which appears to be the same one as reported above. I have the latest compiler versions, and none of the Makefile modifications suggested in similar bug reports fixed the issue.

Up until now I have used the previous version of MadGraph5 (v1.4.8.2) on an older Linux installation, where I had no such issues. Is there any way to resolve this without reverting to an older version of mg5?

Thank you for your help!

I also confirm this problem. I was simply re-building pythia on lxplus5.

It had worked fine for me, before with the same MadGraph 5 version and environment.

Thanks!!

Hi Jason, someone told me this fix that worked for me:

After uncompressing the tar file, instead of doing

mg5> install pythia-pgs ,

manually comment out the line

-fno-second-underscore

from

pythia-pgs/libraries/PGS4/src/stdhep-dir/mcfio/arch_mcfio

and

pythia-pgs/libraries/PGS4/src/stdhep-dir/src/stdhep_Arch

and then type

cd pythia-pgs/src
make libpythia
make

hope this helps.

Stefano,

you are a great one! This solved a long issue for me, since I always was using back an old pythia-pgs directory that was working and could never compile a new one! I always use Fedora, and seems that this is an issue for Fedora may be, because other users do not have this issue.

One add-on or clarification to what you said: you have to comment the lines CONTAINING the "-fno-second-underscore", since the line says more things, and there are many of them. You can just comment out the one corresponding to your distribution, or just comment out all of them.

I have checked that now compiles correctly, and also does the matching of ttbar+j correctly.

Regards, Ezequiel.

Ok, glad this was helpful!
Cheers,

Stefano

Hi stefano,

Have you tried Oliver's solution in #10 of Question #227090? I had exactly the same problem as you some days ago, but now it seems that my pythia works well.

Wish this will help,

Sida

HI Guys,

Sorry looks like that I didn't receive notification for bugs/question which are posted with this project. I hope that this is fixed now.
Thanks Stefano for the fix. I'll look at when this is needed in order to include automatically when needed.

Cheers,

Olivier

[Olivier Mattelaer (olivier-mattelaer)]

Now, this should be done automatically in the version 2.0.1 of MG5_aMC@NLO

Cheers,

Olivier

Hi Olivier, thank you very much, best
