I've instrumented the any_cast code and have verified that the type_info.name() strings for both the stored and requested types are the same. However, the operator== for the type_info's is still returning false.
I'm not sure if that's quite the same problem, but I had similar symptoms with two python extension modules (which are shared libraries, too). The point was that the type_info seemed to be the same, i.e. type_info.name(), but there still were two different instances around. Unfortunately, the compiler does not compare the type_info.name() but the addresses of the instances. See: http://wiki.python.org/moin/boost.python/CrossExtensionModuleDependencies The solution was to link the shared libraries with vague linkage enabled: http://gcc.gnu.org/onlinedocs/gcc/Vague-Linkage.html HTH Bernhard ___________________________________________________________________ Disclaimer: Diese Mitteilung ist nur fuer die Empfaengerin / den Empfaenger bestimmt.
