LNK1104: cannot open cuda.lib // CUDA 6.5 on Qt creator

gj21kr

Hello there,

I want to use my gtx 980 ti for cuda FFT programming.
My project should be coded on Win32 to link various libraries.
So, I installed CUDA 6.5 integrated with visual studio 2010.
My framework for my application is Qt Creator 4.3 with Qt library 4.8.6.

When I compiled my program I got the following error:
LINK : fatal error LNK1104: cannot open file 'cuda.lib'
jom: D:\sdkk_beta_cpy\demo_7\build-qt-Desktop-Debug\Makefile.Debug [debug\QtCuda.exe] Error 1104
jom: D:\sdkk_beta_cpy\demo_7\build-qt-Desktop-Debug\Makefile [debug] Error 2

how can I fix it?

Best,

@gj21kr
where do you have this qmake code from?
QMAKE_LIBDIR should actually be LIBS (use -L to specify the path)

Thanks! I fixed it
