OSX compiling problem: std::binary_function removed

[attilio]

Hello,
with the last version of OSX and c++17 std::binary_function has been removed and Delphes no more compile.

external/PUPPI/puppiParticle.hh:63:34: error: no template named 'binary_function' in namespace 'std'; did you mean 'binary_function'?

Could someone fix it please?

Thanks

Attilio

Thank your for notifying us about this problem.

It should be enough to simply remove binary_function from puppiParticle.hh. I have just removed it with ​this commit.
