Defining -DOS_OBJECT_HAVE_OBJC_SUPPORT=1 in the ${TOOL_NAME}_CPPFLAGS variable in GNUmakefile successfully navigated that set of tests, and then it fell over because dispatch.h #includes <objc/NSObject.h> rather than <Foundation/NSObject.h>. A symlink fixed that :)
So now Server.m compiles. There’s still quite a long way to go to see if it works, apparently we don’t have NS{Mutable}OrderedSet in GNUstep just yet, so I’ll mock one up with an NS{Mutable}Array and an NS{Mutable}Set and see where it barfs next :)
The board that’s running all this is one of these - I still find it kind of amazing that something this small can run “Cocoa” apps :)
Cheers! Simon

Hi all,
So I've just installed Debian (Sid) and got GNUstep installed with runtime 2.0 / clang-8 etc. by following http://wiki.gnustep.org/index.php/Building_GNUstep_under_Debian_FreeBSD#libdispatch <http://wiki.gnustep.org/index.php/Building_GNUstep_under_Debian_FreeBSD#libdispatch> As far as I can tell, it all worked fine. I got a few tests fail where the above link didn't mention, but they seemed to be to do with Objc++, and I'm not planning on using that. I put that down to running sid.
I have a project that compiles on my Mac, and I'm trying to port it over - part of it is a web-socket service, which uses libdispatch and blocks to process the data streams. On the Mac, there aren't any warnings. On the linux box, I get:
nano:~/src/b-leet.com/bleetd <http://b-leet.com/bleetd>> make messages=yes
This is gnustep-make 2.7.0. Type 'make print-gnustep-make-help' for help.
Running in gnustep-make version 2 strict mode.
Making all for tool bleetd...

The GNUmakefile I put together looks like:
---8<------8<------8<--- Cut Here ---8<------8<------8<---
include $(GNUSTEP_MAKEFILES)/common.make
TOOL_NAME = bleetd
bleetd_CPPFLAGS = -Ibleetd/classes/server \
-Ibleetd/classes/websockets
bleetd_OBJC_FILES = $(shell find bleetd -name '*.m')
include $(GNUSTEP_MAKEFILES)/tool.make
---8<------8<------8<--- Cut Here ---8<------8<------8<---
So the question: Would I normally expect a 'dispatch_queue_t' to still be something that can be put into a property in GNUstep ? I'm really only familiar with the Mac side of things - I’m new to GNUstep, and in Mac-land they're reference-counted objects. I guess I’m asking: is this a bug, did I do something wrong during install, or is it expected behaviour ?
Cheers
Simon
