[Rivet] Problem with rivet-bootstrap

[Ben Waugh]

Hi All,

I've just installed Rivet 1.6.0 on my laptop (Fedora 13) using the 
bootstrap script, but I needed a little hack to get it to work, and I 
suspect this is something that you build experts could fix more permanently.

The bootstrap terminates with this error:
make[1]: Entering directory `/tmp/waugh/rivet/build/Rivet-1.6.0/bin'
   CXX    rivet_nopy-rivet-nopy.o
   CXXLD  rivet-nopy
/usr/bin/ld: rivet_nopy-rivet-nopy.o: undefined reference to symbol 
'HepMC::IO_GenEvent::IO_GenEvent(std::basic_istream<char, 
std::char_traits<char> >&)'
/usr/bin/ld: note: 
'HepMC::IO_GenEvent::IO_GenEvent(std::basic_istream<char, 
std::char_traits<char> >&)' is defined in DSO 
/home/waugh/local/rivet/lib/libHepMC.so.4 so try adding it to the linker 
command line
/home/waugh/local/rivet/lib/libHepMC.so.4: could not read symbols: 
Invalid operation
collect2: ld returned 1 exit status
make[1]: *** [rivet-nopy] Error 1
make[1]: Leaving directory `/tmp/waugh/rivet/build/Rivet-1.6.0/bin'
make: *** [all-recursive] Error 1

This seems to be because the linker line does indeed not contain the 
relevant library. I worked around this by editing 
/tmp/waugh/rivet/build/Rivet-1.6.0/bin/Makefile, changing this line
  LIBS =
to
  LIBS = ${HEPMCLDLIBS}
then running "make" in this directory and then rerunning the bootstrap 
script.

Cheers,
Ben
