Nicola,
Thanks for your reply. I've pasted in a small snippet of the make
output below. These are deprecation warnings related to ObjC 2.0.
The vast majority of the deprecated items are in runtime.h, but there
are a few other declarations in other headers that are deprecated as
well. The items are marked with the macro OBJC2_UNAVAILABLE, which
has the underlying definition of "__attribute__((deprecated))".
An alternative is to execute make as 'make OBJCFLAGS="-Wno-deprecated-
declarations"', but my hope was that this could be incorporated into
target.make since I can't think of a reason someone would want these
warnings enabled.
Below the make output snippet, I pasted in the corresponding snippet
of runtime.h that generates these warnings. I hope this is enough
information to be helpful, but let me know if you need something else.
Thanks,
Blake

Hi Blake
Sorry for not answering before - I don't have Leopard, so I don't
really know what warnings you are trying to suppress. ;-)
Can you send us the output of 'make messages=yes' on Mac OS X that
shows the warnings you are wanting to suppress ?
Thanks

I sent this a few days back and haven't heard anything so I thought
I'd try again. I'm not sure if I haven't heard anything because
few people are running Leopard, this isn't a patch people think
should be applied, or if everyone is simply busy with other things.
Whatever the case may be, if anyone can spare a few minutes to
consider this patch, I'd appreciate it. Two specific questions I
have are:
1) Is target.make an okay place to put this or should individual
GNUstep sub-projects make their own decision on whether to add this
to their relevant makefiles?
2) Is INTERNAL_OBJCFLAGS the correct variable to which this
compiler setting should be added?
Thanks,
Blake

Subject: PATCH: suppress deprecation warnings on OS X Leopard
The following patch modifies target.make so that it adds the
compiler option -Wno-deprecated-declarations when compiling
GNUstep on Mac OS X 10.5 (Leopard) using Apple's GCC. Is this
kind of wholesale disabling of warnings okay, or should this be
done on an individual GNUmakefile level?
Thanks,
Blake
