[Rivet] rivet 2 on Mac OSX

[Hannes Jung]

Dear Riveters

still having problems to get rivet 2 installed on Mac OSX Mavericks

following the advice of Andy at our CMS meeting on Friday, I tried
to compile everything using clang and clang++ with the command:

INSTALL_PREFIX=$HOME/software/rivet CC=clang CXX=clang++ MAKE="make -j8" ./rivet-bootstrap


but then I got an error on fastjet:

libtool: compile:  clang++ -DHAVE_CONFIG_H -I. -I../../../include/fastjet -O3 -Wall -g -Woverloaded-virtual -DDROP_CGAL -I. -I./../../../include -MT libCDFcode_la-JetCluAlgorithm.lo -MD -MP -MF .deps/libCDFcode_la-JetCluAlgorithm.Tpo -c JetCluAlgorithm.cc<http://JetCluAlgorithm.cc>  -fno-common -DPIC -o .libs/libCDFcode_la-JetCluAlgorithm.o

          int dIEta = abs(iEtaSeedTower - iEtaPreClusterTower);
                      ^~~

              ^
2 errors generated.
make[3]: *** [libCDFcode_la-JetCluAlgorithm.lo] Error 1


Any idea to solve this ?
Is this just a Mac problem ?

Thanks a lot
Cheers
Hannes
