You allocate the memory via the usual "new" keyword, the problem here is that the so allocated memory can be moved by the GC at any time. So this could mean that in the usage code (inside the library) the memory is at another place...which is (very) bad...
Allocate the memory with GC.malloc and as flags use NO_MOVE and NO_SCAN, after usage you need to free it manually.

Hi,

I created Derelict-style OpenCL bindings (mdparker/Derelict3#102).
I also edited cl4d so it can use them (https://github.com/vuaru/cl4d).

Perhaps you could take a look at them.

I also edited the VectorAdd example :)

If you build it in non-release mode for example

rdmd.exe --force --build-only --chatty -version=CL_VERSION_1_1 -d -gc -w OpenCL.lib -ofVector VectorAdd.d

it crashs because something somewhere violates a assert :(

Well a big question is how to deal with backward compatibility and OpenCL extensions.

In the long run it isn't practical to support every OpenCL version in the wrapper. They already removed functionality in v1.2 so I have to write different code for < 1.2 and >= 1.2

Extensions need to be properly supported with dynamic loading like Derelict does.

after commenting out the CLObjectCollection destructor like said in issue #1 i still cant build cl4d:

opencl\memory.d(164): Error: function opencl.c.cl.clGetMemObjectInfo (const(void_) memobj, uint param_name, uint param_value_size, void_ param_value, uint* param_value_size_ret) is not callable using argument types (const(void_),uint,uint,const(void_),typeof(null))
opencl\memory.d(164): Error: cannot implicitly convert expression (& info) of type const(void)* to void*
opencl\buffer.d(102): Error: template instance opencl.memory.CLMemory.getInfo!(const(void*),clGetMemObjectInfo) error instantiating

this simple cmd line build of cl4d makes dmd 2057 "stack overflow" :

dmd opencl\c\cl.d opencl\c\cl_ext.d opencl\c\cl_gl.d opencl\c\cl_gl_ext.d opencl\c\cl_platform.d opencl\c\opencl.d opencl\all.d opencl\buffer.d opencl\commandqueue.d opencl\context.d opencl\device.d opencl\error.d opencl\event.d opencl\host.d opencl\image.d opencl\kernel.d opencl\memory.d opencl\platform.d opencl\program.d opencl\sampler.d opencl\wrapper.d

unfortunately cl4d does not link on osx. any ideas ?

How did you get OpenCL.lib? I need equalent for linux platform to provide crosspaltfom support.

Because it is not possible to use them directly within nothrow methods/functions
