[Lilux-help] GCC

Hi I'm trying to compile a c++ program on kubuntu 7.10, but it doesn't. A while ago, all went fine. I suppose, there was an update for some package needed for compiling. Here are the failure messages: gcc filterhtml.cc -o filterhtml /tmp/ccIsh2ZJ.o: In function `__static_initialization_and_destruction_0(int, int)': filterhtml.cc:(.text+0x23): undefined reference to
