Re: Great Moments in Mystifying Compiler Messages...

[Ivan Vučica]

When you're compiling software, your build directory is not
referenced; instead, the installed frameworks are referenced. If you
are sure you want to add a file, add it to Source/GNUmakefile.
However, you almost certainly don't want to do so in this case. (Which
file would you be copying, anyway?)

Greg, Cocoa does seem to contain NSErrors.h, although it's obscure. It
seems to only define several externs for NSString constants referring
to various exceptions, such as NSTextLineTooLongException or
NSWindowServerCommunicationException. These seem to be already defined
in AppKitExceptions.h.

J., ToyViewer seems to be #ifdef'ing this in case __COCOA_ is defined.
At least this piece of its code does:
  
http://svn.gna.org/svn/gsimageapps/trunk/Applications/ToyViewer/TVCtrlPBService.m
So what you want to do is simply remove these lines or add #ifdef
__COCOA_ around this header. Then contact maintainer of the app and
submit a patch.

 Alternatively, check why __COCOA_ ends up being defined for you.
