I have tried all possible methods to avoid this problem (double quotes, put files into program folder...). This is known bug in OpenCL compiler. Till yesterday I knew that it was only for nVidia driver. But now I see that it also happens for AMD. The worst is that I can't reproduce this problem on my machine (it uses double quotes properly - AMD under Vista). I also took into consideration to load mandelbulber_cl_data.h file in the same way like other files. Unfortunately this method will make difficult debugging the code (numbers of code lines will be wrong when compile error occurs). I also can't hardcode path in #include command, because under different systems this path can be different.
Only idea what I can change is location of includes. What will be the best folder under Windows instead of "Program files" which has no spaces in path?

Hi,

have the exactly same problem on my second workstation (IBM QuadCore) with Win7Pro64SP1 too...
(GFX Card here an AMD HD4850 - so an different driver)
Maybe Win7 related ? (or the German version ? )

Simply - create an folder (like OpenCL directly on C:\ -> C:\OpenCL ) - if the known problem is gone with the compiler, the folder can be deleted/moved back to the programm folder ...

Not just "no blank spaces" but under win7 people have been having all kinds of major problems with MS's " Program Files" and windows royally messed up UAC ( read as FUBAR'ed UAC )

non "Administrator" accounts sometimes can not write to the program folder if it is in "Program Files"

a good option might be
C:\\Mandelbulber
or
C:\\MandelbulberOpenCL
or ( if you do not want to type a long name into "cmd.exe"  or did not turn on "Open CMD here" in win7 )
C:\\MCL

I have developed some nice workaround for this problem. I read in many forums that there is not possible to pass any parameter with spaces for OpenCL compiler (e.g. -I include path, -D define....). I started to look for alternative way to put something directly but dynamically into code. I use following method:

- in OpenCL kernel instead of #include "mandelbulber_cl_data.h" I use macro #include INCLUDE_PATH_CL_DATA
- in C++ code I stitch following header before first file with the code: #define INCLUDE_PATH_CL_DATA "/usr/share/mandelbulber/cl/mandelbulber_cl_data.h" (or some other, depends on OS and program folder path)
- additionally first line of the kernel code is modified to stat with double slash (//*********************). Then "#define..." will be in the first line of kernel code and don't make any additional line. So when there will be any compiler error I will still have proper line numbers.

This method passed first trials, so it looks promising

Buddhi. Cant wait to try it out as I too have been stopped by error -43 on AMD A10-5800GHz Radeon HD 7660D, plus my crappy laptop AMD. I had wondered why in GPU Caps Viewer the Open CL demos worked but Mandelbulber wouldn't compile.

This method to fix the problem with include path works well (tested under Linux with AMD and nVidia and under Win Vista with AMD). I think it is good information for all nVidia users (some AMD also). Today I released version 1.20 which should work properly with OpenCL under Windows.
