compile problem

Hi all, I use setenv CXX gcc and then ./configure --prefix=/usr/local/mysql. No problem appear. then I use gnu make to continue the process. It gives the following error: Undefined first referenced symbol in file __cxa_pure_virtual

configure problem

I get the following error: checking return type of sprintf... configure: error: can not run test program while cross compiling when I type ./configure in the source directory of mysql-3.23.39 so I can't install mysql. Why? Thanks -
