installation problem for delphes-3.0.12

[chenning]

hi,

I got the following Error information when installing the latest Delphes-3.0.12:

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: * [libDelphes.so] Error 1

And I also tried to install under the current version of Madgraph5, which is MG5_aMC_v2_1_1 , I also got the same Error message returned as above. I am using an OS X 10.9.2. Hope to figure out how to fix this problem. thanks a lot.

Looks like a problem with your ROOT installation.

This problem is discussed on the ROOT forum:

​​http://root.cern.ch/phpBB3/viewtopic.php?f=3&t=17190&start=75

The solution is to

• upgrade to the latest Xcode
• install the latest command line tools
• built the latest ROOT from sources
• point all the environment variables to the correct ROOT installation directory

Last week, I've tested this solution myself.

Here is what I've done to correctly build ROOT and Delphes under Mac OS X 10.9:

• removed old MacPorts - ​https://guide.macports.org/#installing.macports.uninstalling

• installed XCode 5.1 - ​https://developer.apple.com/downloads
• installed XCode command line tools - "xcode-select --install"

• installed XQuartz 2.7.5 - ​https://xquartz.macosforge.org/landing/

• installed MacPorts 2.2.1 - ​http://www.macports.org/install.php

• installed ROOT 5.34.18 using the following commands:

  version=5.34.18
  export ROOTSYS=$HOME/root/root-${version}
  
  curl -O ftp://root.cern.ch/root/root_v${version}.source.tar.gz
  tar zxf root_v${version}.source.tar.gz
  
  cd root
  
  ./configure macosx --enable-gdml --enable-minuit2 --enable-roofit --enable-table --enable-unuran --disable-cocoa
  
  make -j 4
  make install
  

• installed Delphes using the following commands:

  # setup ROOT environment variables
  export ROOTSYS=$HOME/root/root-5.34.18
  export PATH=$ROOTSYS/bin:$PATH
  export PYTHONPATH=$ROOTSYS/lib:$PYTHONPATH
  export DYLD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH
  
  wget http://cp3.irmp.ucl.ac.be/downloads/Delphes-3.0.12.tar.gz
  tar -zxf Delphes-3.0.12.tar.gz
  
  cd Delphes-3.0.12
  make -j 4
