Setting include path

[Sukumar R]

Hi all,

I've recently downloaded and installed gcc-3.2.3. But when I try
compiling a sample C++ program using the newly installed g++3.2.3, the
errors I'm getting are:

$ which g++
/home/rsukumar/privatePrgms/g++_3.2.3/objdir/gcc/g++
$
$ g++ a.cpp
a.cpp:1:22: iostream.h: No such file or directory
a.cpp: In function `int main()':
a.cpp:6: `cout' undeclared in namespace `std'
a.cpp:6: `endl' undeclared in namespace `std'

How can I set the include path for all the standard header files? So
that compiler can refer to the header files available in the newly
installed directory.

$ find . -name include -type d
./g++_3.2.3/gcc-3.2.3/boehm-gc/include
./g++_3.2.3/gcc-3.2.3/gcc/doc/include
./g++_3.2.3/gcc-3.2.3/include
./g++_3.2.3/gcc-3.2.3/libffi/include
./g++_3.2.3/gcc-3.2.3/libjava/include
./g++_3.2.3/gcc-3.2.3/libstdc++-v3/include
./g++_3.2.3/objdir/i686-pc-linux-gnu/libstdc++-v3/include
./g++_3.2.3/objdir/i686-pc-linux-gnu/libffi/include
./g++_3.2.3/objdir/i686-pc-linux-gnu/boehm-gc/include
./g++_3.2.3/objdir/i686-pc-linux-gnu/libjava/include
./g++_3.2.3/objdir/gcc/include
