Hello,
I'm getting troubles at the compilation step with a very simple code.
Unfortenatly the compilation error message is quite misty for me.
A small tar file can be found under :
/afs/in2p3.fr/home/g/greder/public/test.tar.gz
cd in compile directory and start a root session :
.x Compile_package.C
you will get this message :
************************

Error in <ACLiC>: Compilation failed!
I don't even understand why there is a claim about the copy constructor.
if now you go in the directory physics_objects/ and
you commnent in the file Physics_Objects.C teh line :
#include "mc_particle/MCParticle.C"
and in the file Physics_Objects_linkdef.h the line :
#pragma link C++ class MCParticle+;
to avoid the compilation of the class MCParticle
everything works fine.
I really cannot figure out where the pb stands,
help would really be appreciated,
i'm running on Red Hat 7.2 with :
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)
under ROOT version 3.04/02
thanks,
seb.
