Compile QtOpenCl.dll with Qt (64bit)

[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.

[SGaist]

Can you post the current content of your pro file ?

Just to be sure I understand you correctly, you are again getting the missing symbols error ?
