I've been attempting to test Lockfree (while at the same time learning to
work with boost from trunk, so bare with me I'm a bit new) using Clang 4.0,
the version that will ship with Xcode 4.5. It appears that the
preprocessor check is only for gcc. If I change:
#if __cplusplus < 201103L
#if __cplusplus < 201103L && ( defined( __clang__ ) && !
and compile the examples with (from libs/lockfree/examples):
../../../bjam toolset=clang cxxflags="-std=c++0x -stdlib=libc++"
Then the examples work correctly (queue output: "produced 40000000
objects. consumed 40000000 objects."). I'm sure there is a more elegant
way to check for libc++ existence when compiling with clang, possibly with
Also, I think a message in the dummy main would be nice to inform the user
that lockfree won't work with their current setup / compile method.
