How to compile ICE1.4 with ACE?

I want to use some class in ACE(adaptertive communication environment)
,but when I include ace include file in front of ice include file,some compile
error happens,

Error info in VC6.0:

In addition, when build ACE, you should define ACE_HAS_WINSOCK2 to 0 in your config.h file because Ice includes winsock.h instead of winsock2.h.

There is a bug in ACE when ACE_HAS_WINSOCK2 is defined to 0. In OS_NS_sys_socket.inl, the SD_SEND at line 105 should be changed to ACE_SHUTDOWN_WRITE, and SOCK.h be included at the begining of the file.

Is it possible to use winsock2 in Ice now?

Ice uses Winsock 2 since the very first release.

I don't understand. There is some code in IceUtil\Config.h like this:

// MFC applications that include afxwin.h before this header will cause
// windows.h to skip inclusion of winsock.h, so we include it here if
// necessary.
//
# ifndef _WINSOCKAPI_
# include <winsock.h>
# endif

Isn't winsock.h for Winsock 1.1?

Ice links with ws2_32.lib, which is for the Winsock 2 DLL.

So could the above code be changed to the following code?

# ifndef _WINSOCK2API_
# include <winsock2.h>
# endif

That could make other libraries' lives easier, just like the case with ACE.

Yes, you can simply include winsock2.h. I just tested it.

In IceUtil/config.h,
simply #include <windows.h> will cause <winsock.h> be included (not MFC project),
and which confict with <winsock2.h>.

If #define WIN32_LEAN_AND_MEAN added before <windows.h> will be better.

What is a bit tricky with ACE is, that it instantiates some singelton (global) objects (like the object manager by replacing the standard int main ( ... ) by an own macro (containing the instantiation code). In general you can get around this by certain compilation options described in the ACE documentation (search for ObjectManager ...), however there might still be some conflicts.

We are using both libraries in combination. The way how to do it is by NOT intermixing ICE and ACE includes. We separated out those components responsible for communications (via ICE), encapsulated them and used the pointer-to-implementation (pimpl) idiom to keep the ice includes (or ace includes) out of our include files. So each compilation unit has either ice includes or ace includes ... both never a mix of them.

This approach works perfectly !
