Delphes does not even begin to compile

[J. A. Aguilar Saavedra]

Hi, I'm trying to compile Delphes 3.5.0 on a M2 Max Mac, with Mac OS Ventura 13.2.1 and Xcode 14.3.

Installing from MG5 did not work (I have MG5 running with gcc-13 and python 3.10 from homebrew). I then downloaded and tried to install independently. I have root 6.26.06_2 from homebrew too. I'm not sure which c++ compiler it is trying to use, I just type

./configure
./make

It gives a plethora of errors that seem to show some incompatibility with the current Xcode version. I include them in attachment.

Thanks, and best regards.

Makefile in Delphes 3.5.0 does not work with the recent MacOS versions. I have fixed it with following commit:

​​​https://github.com/delphes/delphes/commit/910bd98482a3df7e7cf0ce045827fe60b903cb1c

I think the easiest solution would be to use the latest Delphes version from the following link:

Thanks, but it does not work either. It seems to give the same series of errors, beginning with

Generating tmp/classes/ClassesDict.cc

I have just updated MacOS, Xcode, command line tools and downloaded ROOT from the following link:

​https://root.cern/download/root_v6.28.04.macos-13.3-x86_64-clang140.tar.gz

I can still build the latest version of Delphes from github.

The ROOT version installed via brew works with MacOS 12 but not with MacOS 13.

Thanks a lot for the tip. For the record: I have installed the pkg version specific for ARM:

root_v6.28.04.macos-13.3-arm64-clang140.pkg

The package installer for root works perfectly, I only had to add the bin folder to the path, so that root-config is found. Then, delphes compiled, with the usual warnings and complaints. I guess it used the compiler bundled with Xcode.

I ran some events through pythia 8 with HepMC3 and then with DelphesHepMC3 and the result seems correct. Thanks again!
