Error when installing ExRootAnalysis and Delphes on macOS 12.6


I have successfully installed root (v. 6.26/06), MadGraph5 (v. 3.5.0) as well as pythia8 on a macOS 12.6 platform. However, when installing ExRootAnalysis and Delphes obtain the following error:

clang: error: invalid deployment target for -stdlib=libc++ (requires OS X 10.7 or later)
make: *** [] Error 1
Error detected during the compilation. Please check the compilation error and run make manually.

Does anyone know what could be the issue? It says I need macOS X 10.7 despite having macOS 12.6.

Best regards,

ROOT Version: 6.26/06
_Platform: MacOS 12.6

Hi @yburkard,

In principle, this is not related to ROOT but to Delphes. The error above suggests that to build the library, you need at least macOS X 10.7. Unsure as to whether it can be made to compile on your platform by tweaking build flags.

Perhaps you can contact the Delphes team here.
