I don't know what site you found but the GCC team does not provide binary 
packages for your platform. So, this is not the right place to ask for such
things. But the GCC homepage lists these resources for the Microsoft Windows
platform (http://gcc.gnu.org/install/binaries.html):

* Cygwin  http://sources.redhat.com/cygwin/
* MinGW   http://www.mingw.org/

Both of these provide http mirrors of their downloads. Cygwin uses a setup
program which automatically retrieves and installs the requested packages.
Note, that you need to specify GCC explicitely as it is not part of the
default Cygwin installation.

If you need a C/C++ compiler for DOS, then just have a look at DJGPP
(http://www.delorie.com/djgpp/). There are also a few http mirrors available
to download from.

There is also a IDE called Dev-C++ (http://www.bloodshed.net/devcpp.html)
which uses the MinGW port of GCC available for free (GPL).

gcc/ g++ Linking Issues

[Johnsy George]

Hi,
I'm having a problem while linking a dynamic library which was created using
gcc
 with a .cpp file using the g++ compiler.Each time I link I get an error of
undefined symbols.
Here is the command :
For creating dynamic library I use:
gcc helloworld.c -dynamic helloworld
#this creates a helloworld dynamic library.

Here's the command to link:

g++ hello.cpp  -lhelloworld
error : undefined symbol printhello
Here helloworld is a library in which a function called printhello() is
implemented which is
used by hello.cpp.
Please let me know if you have any suggesstions.

RE: gcc/ g++ Linking Issues

Johnsy,

Do you have your include file in an 'extern "C"' block?  For example, in hello.cpp, you could have

extern "C" {
#include "helloworld.h"
}

Or in helloworld.h, you could check to see if the file is being included using a C++ compiler and adding the 'extern "C"' block in the header file something like this:

#ifdef __cplusplus
extern "C" {
#endif

<--helloworld.h internals-->

#ifdef __cplusplus
}
#endif

If you don't have something like this, your problem is probably that C++ "mangles" symbol names in order to be able to include the function signature in the name.  It's this feature that allows you to do function overloading - it generates a unique symbol name for each overloaded function, even though the functions have the same name.  The problem in this case, is that C doesn't do that, so when you compile your C++ program with the template to your C function, if you don't tell the compiler that the function should use the C calling convention (no mangled names) via the 'extern "C"' block, the compiler will mangle the name, and will not be able to find the symbol in the C library.

Does that make sense?

Cheers,
Lyle
