Actually there is symbol resolution problem with dynamic_cast between gcc C++ runtime lib and libjvm. For this reason, my application crashes. The libjmv.so provided by IBM is compiled with gcc 2.95 and my application is running on gcc 2.96. I can't change libjvm or to downgrade the compiler version of my application. As a result, application dumps the core at runtime during the symbol resolution of dynamic_cast. So i need some alternative of that. -----Original Message----- From: Falk Hueffner [mailto:falk.hueffner@xxxxxxxxxxxxxxxxxxxxxxxx] Sent: Friday, January 02, 2004 5:27 PM To: Jyotirmoy Das Cc: gcc-help@xxxxxxxxxxx Subject: Re: Alternative of dynamic_cast "Jyotirmoy Das" <Jyotirmoy_Das@xxxxxxxxxxx> writes: > I don't want to use dynamic_cast.

Not possible in a portable way. Why not just use dynamic_cast? -- Falk
