Ice3 compiling error with gcc 4.1.0

[umber]

Hello, Ice developers,

I understand that gcc 4.x is not supported right now. I tried to fix the problem myself, but with no luck with my limited C++ experience. So I posted the error message here in the hope that you may come up with some quick fix or some suggestions.

I am using Fedora Core development branch. 'gcc -v' displays information as below:

I found that there is a declaration of

IceInternal::decRef(IceProxy::Ice::Router*)

in Proxy.h.

But I can not understand why it is not found by the compiler. Is this a problem of Ice or a problem of the compiler?

Thanks,
Guo

And may I ask another basic question here about the "CommunicatorI.cpp"?

I saw that there is a include statement at the beginning of the file
#include <Ice/CommunicatorI.h>

Since Communicator.h is at the same directory with CommunicatorI.cpp, not in the ../../include. As my understanding, usually it will be included as "CommunicatorI.h".

Is there any specific reason it is included in the former form? Thanks.

I'm afraid we can't help with the GCC 4.1 problem. We have not tested Ice with GCC 4.1 yet (it is not yet a supported compiler). If you have a commercial need for using Ice with this compiler, please contact us at info@zeroc.com.

We include all C++ header files prefixed with "Ice/", because this makes it easier to move files from private to public or vice versa, should the need arise. In any case, this is purely an internal coding style issue, and has no impact on applications that use Ice.
