Madgraph after Mac Big Sur upgrade

Hi,

As usual with Mac, we have to tweak stuff to make it work on their latest OS.
So you have to use the latest version of the code to have it working on Big Sur.
But support is quite preliminary for Big Sur so far.

Cheers,

Olivier

Hi Olivier,

Thank you for your prompt response. I downloaded MG5 v2.9.2 but I'm still getting troubles:

Any thoughts?

Best,

Did you re-install the command line tools for Big Sur?
xcode-select --install

Cheers,

Olivier

Yes, it is already installed:

xcode-select: error: command line tools are already installed, use "Software Update" to install update

Also, no update is available.

Looks like it is corrupted:
according to https://stackoverflow.com/questions/63592445/ld-unsupported-tapi-file-type-tapi-tbd-in-yaml-file <https://stackoverflow.com/questions/63592445/ld-unsupported-tapi-file-type-tapi-tbd-in-yaml-file>
you will need to remove it and re-install it.
(they also advise to re-install gcc, I typically advice to not install gcc on mac (just gfortran)

But obviously be very careful with that operation (full back up/...)

Cheers,

Olivier

Thanks a lot. I tried the suggestions on the post you shared and they didn't work.

I will need to keep looking for a different way. Thanks for your help!

Hi all,

I have been re-installing some of the software and now I get a different error message. Maybe this time you can find what I'm doing wrong:

Thanks Olivier Mattelaer, that solved my question.

On another big sur machine, I fixed the same issue with the command:

sudo xcode-select -s /Library/Developer/CommandLineTools/

which is likely a bit cleaner that the suggestion above.
