Real FFT.vi

[MarM]

Hello again,

I was trying to use Real FTT.vi in embeded Project on LPC2294 and ecos but during compilation I get following error:

Real_FFT.c:281: error: invalid storage class for function 'cln_wrapper_1E8'

It’s the same also for another functions form ‘Analyze’. What is wrong here??

Hi Marcin,

The compiler you are using probably doesn't like the way the cIn_wrapper_1E8 is being initialized. To work around this, open the block diagram for the signal analysis VIs you are using (e.g., Real FFT.vi) and double-click on the Call Library Function Node. Select "Run In UI Thread" instead of "Reentrant". This will effect the way C code is generated and likely solve the problem for you.

Michael,

For compilation it did help but now I have different, linker errors like:

            libad.a(ReNIFFTH.o): Relocations in generic ELF (EM: 20)

Marcin,

You will need to build the analysis libraries for the target so they can be linked in. Refer to the Embedded Porting Guide for instructions on building the analysis libraries.
