Error when installing ExRootAnalysis and Delphes on macOS 12.6

[yburkard]

Hello,

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: *** [libDelphesNoFastJet.so] 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,
Yannick

ROOT Version: 6.26/06
_Platform: MacOS 12.6

Hi @yburkard,

@yburkard

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

In principle, this is not related to ROOT but to Delphes. The error above suggests that to build the libDelphesNoFastJet.so 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.

Cheers,
J.
