What am I missing? Your suggestions would be greatly appreciated. <BR /><BR />Thanks,<BR />Dave<BR /><BR />1d DFTs work fine. But when I try to compile the simplest, default 2d real DFT, I get the following error message from the compiler, which results from the DftiComputeForward statement.<BR /><BR />"There is no matching specific function for this generic function reference.
