MadGraph Cannot Complete Tutorial

Cygwin was never supported.
For windows user the best is to easiest is to use the linux kernel that is (optionally?) shipped with all windows 10. I know that they are some issue in that mode (mainly for grahpics and for MadSpin) but otherwise it seems to work ok from report that I received.

Obviously the cleanest method is to install a linux in dual-boot since mainly scientific package offer close to zero support for windows.

Cheers,

Olivier

Oliver,

Thank you for your quick response.
Switching to Windows Terminal with Windows Subsytem for Linux using Ubuntu 20.04 has allowed me to progress further into the built-in tutorial but I still cannot complete it.

After output MY_FIRST_RUN completes with the foot notes:

save configuration file to /mnt/e/MPhys_Project/MadGraph/MG5_aMC_v2_8_1/MY_FIRST_MG5_RUN/Cards/me5_configuration.txt

Which is strange to me as I have gfortran and g++ installed through MinGW and pointed at in the configuration txt file

 the tutorial prompts launch MY_FIRST_MG5_RUN which results in:

Any assistance is appreciated.

Hi,

I do not have experience with windows,
But the path that your provide is a "windows" like path.
However in the linux sub-system I would expect to have "linux" like path.
YOu can see the code printing one of them:

> save configuration file to /mnt/e/MPhys_Project/MadGraph/MG5_aMC_v2_8_1/MY_FIRST_MG5_RUN/Cards/me5_configuration.

But fails to find the following "windows" type of path:
> FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Program'

I do not know if the issue is with madgraph, or simply that C:\\ is not available on the linux sub-system

In this case, I would just install gfortran/c++ for ubuntu via
apt-get install gcc
(or if needed the super-user version: sudo apt-get install gcc)
(Note double check the above command since I'm a red-hat user not a ubuntu one)

Cheers,

Olivier

Thanks for you help and quick responses, this got me past that point and I ran into some other errors which I managed to troubleshoot myself somehow.
