I updated the package to version 3.1.0. However, the python2 patch is not currently working as of the moment so the only way to run this package and use python2 is to python2 /usr/bin/mg5_aMC. Sorry for the incovenience. I am adopting other madgraph packages as well but for some reason, the sources are all over the place. Not the fault of the previous maintainer, they just updated their website and some of packages are now deprecated (e.g. pythia-pgs). If someone can help, pls contact or comment down below.

EDIT: Notice that when you run the program in python2, it will give you a warning that python2 will be deprecated soon on the last quarter of 2021. It might not be feasible to patch it with python2 but feel free to comment. This is my third package and I am quite new to Arch. Thanks.

Yeah. I saw that announcement. However, MadAnalysis5 still needs python2 to work. I wonder when they will drop support for python2 on that or is MadAnalysis5 still needed?

Note: I am not a Physics student. I am helping a friend so that he can use this package. :D

@ronin I believe that Python 3 is meant to be supported from MadGraph v3.0 so it is no longer necessary to include the patch (see this announcement). Note that you might want to update the configuration patch to account for any major changes from v2.x to v3.0.

I no longer use MadGraph, hence the lack of updates.

There appears to be a bug in version 8.x of gfortran that causes at least the tutorial process (p p > t t~) to fail to compile for me, as well as additional processes for others.

See here: https://answers.launchpad.net/mg5amcnlo/+question/668703

edit: Actually, this doesn't appear to be a bug. It's more of a was-a-warning now-an-error type thing. You can force it to compile anyway with the "-std=legacy" option.

For this package, a patch to change line 16 of Templates/LO/Source/make_opts from

FFLAGS= -O -w -fbounds-check -fPIC

to

FFLAGS= -O -w -fbounds-check -fPIC -std=legacy

should fix the issue until it gets fixed upstream.

If you encounter any issues with the package, please let me know.
