Subject: GCC  vs G++

Hi,

I am using Linux. I am not still sure about the difference between g++
and gcc. Is g++ just a wrapper for gcc? I am not sure which one I should
use
for compiling my C++ codes?

____________________________----
gcc is the C front end for GNU compiler.
g++ is the C++ front end.  To a limited extent, each could invoke the other, according to source file suffix naming.  You need both to compile C++, but you use g++ as the command.

g++ is very similar to gcc.  The main difference is that g++ assumes
that it is compiling C++ (gcc will compile C++ for files ending in
".cc", ".C", etc.), and g++ always links against the standard C++
library.

When compiling C++ you should use g++ in all normal cases.

So the way I read this is that I *could* use gcc for compiling .cpp
files that use c++ libraries, correct?  It never seems to work, even
for a simple "Hello, world."

Yes.

It works for me everyday, but I know all the special things I have to do 
on the platform I am using.

The reason to use g++ is that it works with no special non-portable magic.

On my platform,
gcc some_c++_file.cpp -lstdc++
seems to behave the same as
g++ some_c++_file.cpp

I don't know why one would want to use the prior, however.
