This is because you have to instruct the linker to link in the c++ library
if you are using gcc to compile, otherwise the linker can't find the c++
library and you will get undefined references. 

You should add the -lstdcx option if you use gcc.
A example compile would go like "gcc name.cc -o name.exe -lm -lstdcx"
withought the quotes.

Or you can use gpp.exe which will automatically link in the c++ library.

Yes, you have to add the -lstdcx to the compile line if you use gcc... Or
use gpp like "gpp name.cc -o name.exe -lm" .
