Hi all! I'm having problems compiling ns 2.1b5 on FreeBSD 3.1. It stops with: misc.o: In function `VersionCommand::command(int, char const *const *)': /home/andree/ns-allinone-2.1b5/ns-2.1b5/misc.cc:107: undefined reference to `version_string' *** Error code 1 Does anyone know how to get past this problem? Any help would be greatly appreciated. Thanks. /Andree Jacobson; [email protected]
