Compile QtOpenCl.dll with Qt (64bit)

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.

SGaist

How did you compile QtOpenCL itself ? Command line or Qt Creator ? In the second case, did you perhaps configure it with a Kit using a 32bit Qt ?

morflink

in the past i compiled the 32bit qtopencl libraries by the qtopencl project in qtcreator as described in the first post.
i just was trying to do that for 64bit Qt in the same manner with a 64bit compiled qt 4.7.1.
it just dont worked out.

SGaist

Strange, it looks like there's at least architecture mismatching somewhere

morflink

if i get new hardware in the future i prolly will redo all this and maybe find the reason by comparision.
anyways, thanks for your time and your help =)

SGaist

No problem, you're welcome !

Happy coding ! :)
