Can't compile cufftPlanMany

Accelerated Computing CUDA CUDA Programming and Performance

I’m trying to do a batched 2D FFT but I’m not able to compile the call to cufftPlanMany,

cufftHandle           FFTplan_XY, FFTplan_ZT;

	NUMBER_OF_FFTS = DATA_D * DATA_T;

	cufftPlanMany(&FFTplan_XY, 2, { DATA_W, DATA_H }, NULL, 1, 0, NULL, 1, 0, CUFFT_C2C, NUMBER_OF_FFTS);

For the line with “cufftPlanMany” the compiler gives the error

error: expected an expression

I managed to fix it by replacing {DATA_W, DATA_H} with an int with two elements (int sizes[2]). It should be possible to compile the code in the CUFFT documentation right away!
