libEvtGenExternal.so: undefined reference to `Pythia8::Pythia::readString(

[wxie2013]

I'm using PYTHIA8.310 and EvtGen2.2.0 together to compile a code. The following error was produced:

libEvtGenExternal.so: undefined reference to `Pythia8::Pythia::readString(std::__cxx11::basic_string<char, std::char_traits, std::allocator >, bool)'

libEvtGenExternal.so: undefined reference to `Pythia8::Rndm::rndmEnginePtr(Pythia8::RndmEngine*)'

Could there be a version mismatch or I need to add some path to the makefile.

Thanks

I used the following conda command to install ROOT, pythia98 and evtgen:

conda install -c conda-forge root -y
conda install -c conda-forge pythia8 -y
conda install -c conda-forge evtgen -y

Yes, indeed. This is a version mismatch. PYTHIA8.304 works fine with EvtGen2.2.0. Would be nice to update accordingly.

I stumbled upon this while debugging a similar issue. It should be fixed by conda-forge/evtgen-feedstock#5

What's the command to install the feedstock#5? I tried the following but it can't find the packages:

conda install -c conda-forge evtgen-feedstock#5
