Re: Problem with GNUstep and Objective-C++

[Mike Simmons]

Hi, Nicola,

Ultimately the problem was that I was trying the build on a server  
that has a very old version of SUSE Linux and GCC 3.3.3. Now I know  
that Objective-C++ is supported only on GCC 4.1 and newer. I'm pushing  
hard to get the development server's Suse Linux version upgraded to  
the most current release, as well as hundreds of production servers --  
not a small task, particularly because the servers are geographically  
dispersed.

In the interim I'm developing on SLES 10 running on VMware on my Mac.

Thanks again for the help!

Mike
