What you need to do _if_ using gcc instead of g++ ( gxx for djgpp )
[247][ root AT linuxbox: ~/tmp/
# gcc -Wall -o hello hello.C -lg++
[248][ root AT linuxbox: ~/tmp/
which is linking with libg++ (libgpp for djgpp )
thus you should try ...
gcc -Wall -o try try.cc -lgpp
but if you wish not to bother with the -lgpp
just use gxx instead
hope this helps,
ps: ... Hmmm It's in the faq I believe :)
Cheers,
