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 : 

 ************************

No such file or directory
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.
