[Rivet] poblems installing rivet on mac

Hi Hannes,

Thus spake Hannes Jung (hannes.jung at cern.ch):

Well, setting AGILE_GEN_PATH certainly works for me.

This phenomenon is called "default search path" I think.

Let's do a brief test:

mkdir /tmp/gensertest
cd /tmp/gensertest
wget http://service-spi.web.cern.ch/service-spi/external/MCGenerators/distribution/pythia6-424.2-src.tgz
tar -xzf pythia6-424.2-src.tgz
cd pythia6/424.2
./configure --prefix=$PWD --enable-shared
make
make install # ignore error saying pyt_str_s.inc and /tmp/gensertest/pythia6/424.2/include/pyt_str_s.inc are identical
export AGILE_GEN_PATH=/tmp/gensertest
cd /tmp
agile-runmc Pythia6:424 -P lhc7000.params -n 10 -o events.hepmc

Does this work? If yes: Congratulations. If not: What's the error?

Not sure what you mean with "include it again". Agile should support
Cascade. If it's not installed in Genser, talk to the Genser people.

Cheers,
