HepEVT does not work

[bronnum.hansen@gmail.com]

I cannot make events with HepEVT as output. I configured Sherpa with

./configure --with-sqlite3=install  --enable-hepevtsize=10000 --enable-root --enable-hepmc2=/nbi/home/rhj421/HepMC-2.06.09

After making the necessary libraries created in the initial run of Sherpa, running again gives the following output:

...
Initialized the Soft_Photon_Handler.
Library_Loader::LoadLibrary(): Failed to load library 'libSherpaHepEvtOutput.so'.
Sherpa: Initialization_Handler::InitializeTheIO throws missing module: 
   Cannot load output library SherpaHepEvtOutput.
------------------------------------------------------------------------
Please cite the publications listed in 'Sherpa_References.tex'.
  Extract the bibtex list by running 'get_bibtex Sherpa_References.tex'
  or email the file to 'slaclib2@slac.stanford.edu', subject 'generate'.
------------------------------------------------------------------------
Exception_Handler::Exit: Exiting Sherpa with code (1)

I have made the HEPEVT add on:

make SHERPA_PREFIX=../../

Manually moving the .so to the lib/SHERPA-MC/ directory gives the following result:

Library_Loader::LoadLibrary(): /nbi/home/rhj421/SHERPA-MC-2.1.1/lib/SHERPA-MC/libSherpaHepEvtOutput.so: undefined symbol: hepevt_
Library_Loader::LoadLibrary(): Failed to load library 'libSherpaHepEvtOutput.so'.
Sherpa: Initialization_Handler::InitializeTheIO throws missing module: 
   Cannot load output library SherpaHepEvtOutput.

I hope you are able to help Christian

For simple HepEvt output you do not need to build the AddOn. This output option is always available, see http://sherpa.hepforge.org/doc/SHERPA-MC-2.1.0.html#Event-output-formats

Solution was simply to write only capital letters. I.e. "HEPEVT"

Sorry for the inconvenience.
