Re: Problem with GNUstep and Objective-C++

[Nicola Pero]

Hi Mike

I tried following your instructions with gnustep-make from trunk and  
everything worked out-of-the-box. :-)

Can you clarify which version of gnustep-make you were using ?  What  
was the fix that fixed your problem ?
Can you try gnustep-make from subversion trunk and verify that it all  
works out-of-the-box for you as well ?

Thanks for your help
