Build error with -tags="cl12" or -tags="cl20" on NVidia

[LeMoussel]

It's OK when I do go build -tags="cl11" gocl/cl

But with -tags="cl12", I encountered the following error:

gocl/cl/image12.go:47: c_image_desc.buffer undefined (type C.struct__cl_image_desc has no field or method buffer)

and with tags="cl20" this

gocl/cl/image12.go:47: c_image_desc.buffer undefined (type C.struct__cl_image_desc has no field or method buffer) gocl/cl/queue20.go:39: cannot use c_properties_ptr (type *C.cl_command_queue_properties) as type *C.cl_queue_properties in argument to func literal

I'm using Nvidia GT 1030 GPU card on Ubuntu 16.04 With tags="cl11", goclinfo give me this informations
