Compilation Problem

[lokeb]

I am trying to compile it on Ubuntu 14.04, but it stops with an error. Here's the log:

It looks like your version of clang doesn't support blocks. Can you do make messages=yes and paste the output? This should tell you which copy of clang it's using. You can then do path/to/clang -v to find the version.

Although it looks as if you might be using GCC as an Objective-C compiler, which would be a very odd decision as GCC only supports an archaic version of Objective-C.

You are right, but now I have another problem. I compiled libobjc2 from http://download.gna.org/gnustep/. Now it fails while :

Do I have to compile the entire GNUstep from scratch with objc2 support, or there is a simpler way?

[davidchisnall]

Yes, you should compile GNUstep with the an ABI from the last 5 years.
