Compile QtOpenCl.dll with Qt (64bit)

morflink

mb i've got the wrong sdk.... named APP AMD SDK.
there is a so called OpenCLService.exe which i installed via prompt
OpenCLService.exe -i and run it via -s

SGaist

So, it is working now ?

morflink

no its not, still the same errors

SGaist

Do you have any OpenCL something lib file in the AMD sdk ?

morflink

nope
just kernels for examples and stuff

SGaist

Strange, did you do a global disk search ? Sometimes there are things are dispatched in both Program Files and Program Files (x86)

Just to be sure did you download "that":http://developer.amd.com/tools-and-sdks/opencl-zone/opencl-tools-sdks/amd-accelerated-parallel-processing-app-sdk/ sdk ?

morflink

yes, thats what i installed...
i did searched for opencl files... and as i posted before i just found strange files like AMD_opencl64.dl_
i always throught the only thing i need is the opencl.dll (no matter from which source) and compile it with the needed compiler, in my case the amdx64 compiler of msvs10.0

SGaist

no .lib or .a file ?

morflink

the only .lib or .a files are named glew32 and 64 or glut32 64.

SGaist

I wonder if the SDK has installed correctly

morflink

did you see the lib files if you take a look at it ?

morflink

ololol, i searched them manually and found them
dunno why the autosearch cant track them.... OpenCL.lib and libOpenCL.a
what to do now ?

SGaist

Depending on your compiler link to either OpenCL.libg (Visual Studio) or libOpenCL.a if you are using MinGW

morflink

i use MSVS compiler for 64bit... how to link libs in the pro file?

SGaist

You can use Qt Creator built in dialog for that.

Or add

@
LIBS += -Lpath/to/sdk/ -lOpenCL
@

If you want to be independent from the SDK installation path, you can use the environment variables to generate the proper path

morflink

well, thank you so far... now the compiler says:
@NMAKE : fatal error U1077: ""C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\BIN\amd64\link.EXE"": Rückgabe-Code "0x49d"
Stop.
NMAKE : fatal error U1077: ""C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\BIN\amd64\nmake.exe"": Rückgabe-Code "0x2"
Stop.
NMAKE : fatal error U1077: "cd": Rückgabe-Code "0x2"
Stop.
NMAKE : fatal error U1077: "cd": Rückgabe-Code "0x2"
Stop.@

i just added the following:
@LIBS += -LC:/Program Files (x86)/AMD APP SDK/2.9/lib/x86_64 -lOpenCL@

SGaist

Spaces are really bad on windows

try

@LIBS += -L$$quote("C:/Program Files (x86)/AMD APP SDK/2.9/lib/x86_64"@

If that doesn't work, use the 8.3 naming scheme

morflink

if i just use this advice, i get the same errors like i got at the very beginning.
then i tried to copy paste the whole folder to another path without spaces and get still the same errors.
8.3 naming scheme means to give the files in particular like ?:

@LIBS += -L$$quote("C:/Program Files (x86)/AMD APP SDK/2.9/lib/x86_64/libOpenCL.a") -lOpenCl@

SGaist

No, the path itself and don't add the library name since you also pass the -lOpenCL option.

@LIBS += -LC:/PROGRA~1/AMDAPP~1/2.9/lib/x86_64@

Please check the both on the command line with dir /x

morflink

i just checkd and saw that its PROGRA~2 cuz of the standard Programms folder and the x86 one but the errors dont change.
