Hi,
I've set up a build environment with the lastest trunk versions of
GNUstep, clang and libobjc2 on Ubuntu 12.04.
In my program (compiled with ARC) I tried to dispatch a block with
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT,
0), ^ ...
This crashes immediately when the dispatch_get_global_queue call
returns. The stack shows that the compiler executes a "retain" call on
the returned object, but libdispatch does not seem to be compiled with
objc support at all, so I assume that the returned object just is a c
struct.
I used
./configure --enable-debug-by-default --enable-objc-nonfragile-abi
--with-layout=gnustep
for the GNUstep make build and
./configure --disable-mixedabi
for building GNUstep base.
For libdispatch I used the configure provided by the repository at
https://github.com/nickhutchinson/libdispatch.git
I assume that the culprit is in the libdispatch build. I manually
patched the generated config.h file to support OBJC, but this obviously
isn't enough.
From reading posts from this list I concluded that there are people
here that used GNUstep with libdispatch and ARC successfully, so perhaps
someone can give me a hint how I can solve my problem.
Thanks in advance,
Mathias
