Hi, I'm running into the following error: /usr/bin/ld: dbg/clntcore.so: undefined versioned symbol name __dynamic_cast@@CXXABI_1.2 /usr/bin/ld: failed to set dynamic section sizes: Bad value collect2: ld returned 1 exit status I'm on Red Hat 8 (linux) and using gcc 2.95 What caused this error, and how do I get rid of the error? Also what is an ABI???? I've seen reference to it here on the archive but am not sure what purpose it serves. Thanks David Stockwell http://www.leds.com
