Change Details

Here are the instructions that work as of today [August 8th 2023 -- on Mac OS X Ventura 13.4.1 (c)]. - You need the homebrew package manager installed (https://brew.sh) with gcc (currently: 13.1.0) installed as well. This gives you gfortran 13.1.0. - Add this version of gfortran in the herwig-boostrap: ```if platform.system() == 'Darwin': default_cc = os.getenv('CC', '/usr/bin/clang') default_cxx = os.getenv('CXX', '/usr/bin/clang++') default_fc = os.getenv('FC', '/opt/homebrew/bin/gfortran')``` - Using homebrew, “tap” into the homebrew-hep repo (see https://github.com/davidchall/homebrew-hep): brew tap davidchall/hep and install the following: ```brew install fastjet lhapdf boost hepmc3``` Also install the LHAPDF pdfs: ```lhapdf install CT14lo; lhapdf install CT14nlo``` Then run the bootstrap with: ./herwig-bootstrap --herwig-hg --thepeg-hg --with-boost=/opt/homebrew/Cellar/boost/1.82.0_1/ --with-fastjet=/opt/homebrew/Cellar/fastjet/3.4.0_1 --with-lhapdf=/opt/homebrew/Cellar/lhapdf/6.5.3 --with-hepmc3=/opt/homebrew/Cellar/hepmc3/3.2.6/ --without-gosam --without-vbfnlo Herwig-full/ (versions of dependencies will probably change, so they will need to be adjusted accordingly). Herwig will fail on looptools. I found that additional FCFLAGS are necessary (can these be passed via the boostrap?): so I re-configure Herwig with: ./configure --prefix=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-thepeg=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-boost=/opt/homebrew/Cellar/boost/1.82.0_1/ --with-gsl=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-fastjet=/opt/homebrew/Cellar/fastjet/3.4.0_1 --with-madgraph=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/opt/MG5_aMC_v3_5_1 --with-openloops=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/opt/OpenLoops-2.1.2 --with-pythia=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-evtgen=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ FCFLAGS='-w -fno-range-check -fallow-argument-mismatch -O2 -ffixed-line-length-none -DQUAD=0 -DQUADSIZE=16 -DU77EXT=0' And re-run the boostrap as before.

Here are the instructions that work as of today [August 8th 2023 -- on Mac OS X Ventura 13.4.1 (c)]. This will currently exclude GoSam and VBFNLO. - You need the homebrew package manager installed (https://brew.sh) with gcc (currently: 13.1.0) installed as well. This gives you gfortran 13.1.0. - Add this version of gfortran in the herwig-boostrap: ```if platform.system() == 'Darwin': default_cc = os.getenv('CC', '/usr/bin/clang') default_cxx = os.getenv('CXX', '/usr/bin/clang++') default_fc = os.getenv('FC', '/opt/homebrew/bin/gfortran')``` - Using homebrew, “tap” into the homebrew-hep repo (see https://github.com/davidchall/homebrew-hep): ```brew tap davidchall/hep``` and install the following: ```brew install fastjet lhapdf boost hepmc3``` - Also install the LHAPDF pdfs: ```lhapdf install CT14lo; lhapdf install CT14nlo``` - Then run the bootstrap with: ./herwig-bootstrap --herwig-hg --thepeg-hg --with-boost=/opt/homebrew/Cellar/boost/1.82.0_1/ --with-fastjet=/opt/homebrew/Cellar/fastjet/3.4.0_1 --with-lhbapdf=/opt/homebrew/Cellar/lhapdf/6.5.3 --with-hepmc3=/opt/homebrew/Cellar/hepmc3/3.2.6/ --without-gosam --without-vbfnlo Herwig-full/ [versions of dependencies will change, so they will need to be adjusted accordingly -- check the versions installed in your /opt/homebrew/Cellar directory] - Herwig will fail during the LoopTools compilation. I found that additional FCFLAGS are necessary, so I re-configure Herwig by finding the ./configure line in the Herwig-7.3.0/config.log and adding ```FCFLAGS='-w -fno-range-check -fallow-argument-mismatch -O2 -ffixed-line-length-none -DQUAD=0 -DQUADSIZE=16 -DU77EXT=0'''', i.e. in my case, this looks like: ./configure --prefix=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-thepeg=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-boost=/opt/homebrew/Cellar/boost/1.82.0_1/ --with-gsl=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-fastjet=/opt/homebrew/Cellar/fastjet/3.4.0_1 --with-madgraph=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/opt/MG5_aMC_v3_5_1 --with-openloops=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/opt/OpenLoops-2.1.2 --with-pythia=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ --with-evtgen=/Users/apapaefs/Projects/Herwig/Herwig-unstable-full/ FCFLAGS='-w -fno-range-check -fallow-argument-mismatch -O2 -ffixed-line-length-none -DQUAD=0 -DQUADSIZE=16 -DU77EXT=0' [Again, package versions will change!] - After re-reconfiguring Herwig, re-run the boostrap as before.
