g++

[<shashi@fcrao1.astro.umass.edu>]

I upgraded my machine to potato but in compiling a c++
program which before used to work with

g++ -lg++ filename.cc,

now I need

g++ -I/usr/include/g++-2/ -lg++ filename.cc

two questions:

1) WHy do I need the -I now and

2) The second command doesnt work. It complains

/usr/bin/ld: cannot find -lg++
collect2: ld returned 1 exit status

though all the libraraies are in /usr/lib. Any ideas?
