Adding new FastJet/contrib to Delphes

[kwei]

Hi,

I am hoping to add FastJet/contrib/VariableR/ to delphes/external/fastjet/contribs.
​https://fastjet.hepforge.org/contrib/contents/latest.html
There is already Njettiness algorithm in there, so I am following the same way as Njettiness.
Here is what I have done:

1. Copy *.hh in fastjet/contribs
2. Modify FastJetFinder.cc & FastJetFinder.h and add VariableR jet as case9 in FastJetFinder.cc

When I was trying to compile the modified code. Error messages show as:

tmp/modules/FastJetFinder.o: In function `FastJetFinder::Init()':
FastJetFinder.cc:(.text+0xd41): undefined reference to `fastjet::contrib::VariableRPlugin::VariableRPlugin(double, double, double, double, bool, fastjet::contrib::VariableRPlugin::Strategy)'
collect2: ERROR：ld RETURN 1
make: * [pileup2root] ERROR 1

It looks like that there is some problems with the link between files.
Is there any more file to modify to add new algorithm in FastJetFinder?
However, is there more convenient way to plug fastjet contribs into Delphes?

Thank you.

Best,
Kai

Problem solved. I need to do configure a second time.
