Compile QtOpenCl.dll with Qt (64bit)

[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 ?

yes

[morflink]

maybe this is an interessting information...
i just used the 32bit Qt 4.7.1 and the compiled qtopencl libraries... is it possible that there are just older files or installations of whatsoever which causes failures like that?
i simply followed the instructions and maybe this is a reason why is just dont work out as it should.

[SGaist]

This is interesting indeed, you are compiling a 32 bit version of QtOpenCL but you are linking to the 64 bit library. Either rebuild Qt in 64 bit or link to the 32 bit OpenCL libraries

[morflink]

what i wanted to say was, that i used 32bit Qt and opencl1.2 in the past.
i just hope this is no misunderstanding, as i just wrote this down in the very first post.
i alrdy compiled 4.7.1 64bit and it works. what i just tried for now, is getting my older sourcecode work on 64bit, what also needs new QtOpenCL libraries.

[SGaist]

Did you rebuild your old project from scratch ? Also check that you don't have a CONFIG += x86 somewhere in that project

[morflink]

i have nothing like config += x86 in any of the pro files.
but i just works now.
i took QtOpenCL libraries and a few dlls more (opencl.dll, qtopencl.dll qtgui4.dll, qtcore4.dll, msvcp100.dll and msvcr100.dll) from a friend and everything is fine now.
regardless, i cant compile the clinfo.pro nor the rest of the qtopencl project.
just sad that i cant understand whats going wrong here.
