Re: Problem with GNUstep and Objective-C++

[Mike Simmons]

Hi Lucas,

I tried your suggestion, but no luck. Make still fails.

When evaluated, CC turns out to be g++, but the same make failure  
occurs if I force make to use gcc.

I'm running Suse SLES 10, and the g++ compiler version is 4.1.2, if  
that makes any difference.

Any other suggestions? I know it's probably something simple, but the  
solution isn't apparent.

Thanks,
Mike
