Hi,
it seems that compiling osg and specifically OpenThreads is currently
broken for IOS when using xcode 4.3.1. The compilation fails at
OpenThreads/Atomic with
Users/stephan/Documents/Projekte/cefix/cefix/ios/../../libs/ios/include/OpenThreads/Atomic:244:48:
error: cannot initialize a parameter of type 'void *' with an lvalue of
type 'const void *const'
return __sync_bool_compare_and_swap(&_ptr, ptrOld, ptrNew);
Googling around it seems, that this is because of a bug in the
clang-compiler: http://llvm.org/bugs/show_bug.cgi?id=11280
Has anybody an idea how to fix the issue? In the meantime i'll switch to
_OPENTHREADS_ATOMIC_USE_MUTEX
cheers,
stephan
