include - directive

Hello,

I has some include and will compile the kernel-function. I do that with
// Language: Scala
val file = new File("opencl/main.cl")
val dir = new File("opencl/")
program = context.createProgram(new FileInputStream(file))
val cfg = program.prepare
cfg.withOption("-I "+ dir.getAbsolutePath)

program = cfg.build // boom --> error

error message:
Cann't build Program
com.jogamp.opencl.CLException$CLBuildProgramFailureException:
Exception in thread "main" com.jogamp.opencl.CLException$CLInvalidProgramExecutableException: unable to create Kernel with name: computeImage
CLDevice [id: 139942249771808 name: GeForce 9800 GT type: GPU profile: FULL_PROFILE] build log:
:38: error: 'constant.cl' file not found
#include "constant.cl"
         ^

#include "geometrie.cl"
... and so on

It's possible to link opencl-files with jocl?
All files are in the opencl directory.

The path to the opencl directory was
"/abc/ade sdgfe/opencl"

with
"/abc/ade_sdgfe/opencl"
works the opencl compiler. Is this a problem with the jocl implementation or with the nvidia sdk?

What does the underscore mean in your case? Path seperator or whitespace?

I prefer using simple String concatenation to create programs since it ensures best portability. I haven't used the include mechanism yet. But it should work... its completely jocl independent, all IO is done by the OpenCL implementation.

Ok. With withespace the compiler doesn't found the include files.

  whitespace is usually not a path seperator, thats why i asked. Usually
it is : or ; dependent on the OS.

Directory-Name with whitespace
e.g. Windows XP - 6 german
C:\Dokumente und Einstellungen\...
or
/home/myName/dev/Viewer OpenCL\...

OpenCL can not found any file in a directory, that path has a withespace.

you will have to escape the whitespace character otherwise the OpenCL impl might interpret it as multiple compiler arguments instead of one argument.
