Description garnier 2006-04-04 06:00:20 CEST

Hello,

My configuration is PBG4 10.4.5 with gcc4.0.1
I want to create shared lib for geant4. I manage to do it, but when I
linked my application on them it crash...

The crahs reporter show me that :

11  vgm_test.exe     	0x000021dc start + 60

And with gdb it's a little bit better :
(gdb)

Any solutions ???

Comment 1 Gabriele Cosmo 2006-04-05 02:56:59 CEST

Functionality of dynamic libraries on the latest versions of MacOSX is currently broken.
We are investigating how to overcome the restrictions imposed by the system for static and
external symbols, although it is not clear at the moment if all are solvable in a clean way.

Comment 2 Gabriele Cosmo 2006-04-06 10:05:59 CEST

The problem is fixed by modifying the compiler options for generating the
libraries and linking.
The fix is included in the internal tag "config-V08-00-00" and will be
part of a next release or patch.

You can try it out by cut&paste the text below (after ------) and replace the
contents in the file:
  geant4/config/sys/Darwin-g++.gmk
in your setup.
