Hi,

What is you version of MacOS? and the same question for GCC?
MacOS is a quite sensitive setup due to their history of cpu. You need different type of flag for different version of MacOS (and for different type of cpu). So given that 2.6.5 is super old, you will likely need a support old cpu hardware (and that old version of MacOS).

If you have recent version of GCC/MacOS (or recent CPU) the best is likely to use recent version of MG5aMC.

Cheers,

Olivier

Hi Oliver !

MacOS version:
14.2.1 (23C71)

Seems like its using clang:

Sadhanas-MacBook-Air:bin sadhanaverma$ gcc --version

Apple clang version 15.0.0 (clang-1500.1.0.2.5)

Target: arm64-apple-darwin23.2.0

Thread model: posix

InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

Sadhanas-MacBook-Air:bin sadhanaverma$

Though when I tried to download gcc :

gcc version: Sadhanas-MacBook-Air:MG5_aMC_v2_6_5 sadhanaverma$ brew install gcc

==> Downloading https://formulae.brew.sh/api/formula.jws.json

########################################################################################################################################################################### 100.0%

==> Downloading https://formulae.brew.sh/api/cask.jws.json

########################################################################################################################################################################### 100.0%

Warning: gcc 13.2.0 is already installed and up-to-date.

To reinstall 13.2.0, run:

I want same version of MG5 (v2.6.5) which I am using inside CMSSW area (gridpack workflow mode).
So I am trying to do this.

Thanks and Regards,
Sadhana

Hi,

I guess this will be quite difficult to support such old version of madgraph on such recent version of OSX.
(especially given your CPU). Mixing old and new are typically bad idea.

You will likely need GCC8 and gfortran8 (do not link to clang) which you will not find pre-compile for your arm cpu (but you will find it for intel --and this will work thanks to rosetta2-- but the question if it this will be compatible with your recent OS.

Additionally, Feynman diagram generation are not currently not working on OSX 14.X, in OSX 13.X we do have a work around that can also work for 14.X if you have latex install (in principle). Obviously such work-around are not available for 2.6.5 and therefore do not expect to be able to display diagrams.

I would strongly suggest to move to our LTS version (which is the default now in CMSSW) which
1) does support python3
2) support recent version of GCC
3) support recent version of MacOS
4) which does allow pure ARM instruction (so running faster than compiling for x86 but running on arm)
5) does implement better matrix-element evaluation (typically 2-4 times faster evaluation)
6) does fix many many bug (and LTS is bug fix only since more than three years now)

Cheers,

Olivier
