Unable to install Delphes on Mac OS 12.1 (clang-11: error: linker command failed with exit code 1)

[Michele Lucente]

Hi,

I am trying to install Delphes 3.5.0 on Mac OS 12.1, but after the "make" command I get the following error:

>> Building libDelphesNoFastJet.dylib
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
clang-11: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libDelphesNoFastJet.dylib] Error 1

My ROOT installation works fine (although I had to downgrade Command Line Tools from 13.1 to 13 to make it work).

I tried to install as well from MadGraph (i.e. "install Delphes"), but I get the very same error.

Thank you,
Michele

Hi Michele,

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:

​​​​​​​​https://github.com/delphes/delphes/archive/master.zip

I have just tested it with MacOS 12.1, ROOT 6.24.06 installed using the brew package manager and the command lines tools 13.2. Everything works without any problem.

Best regards,

Pavel
