This is probably off-topic for comp.dsp; it's more a question on how
to use GNU-style configure scripts.  However, note that you can

a) specify a particular C preprocessor (e.g. ccppc -E) by using ./
configure CPP="ccppc -E" on the command line to set the value of CPP

b) look in config.log to find the specific error message that caused
invocation of cpp to fail.

Good luck!

Hi all,

I am planning to use fftw library for one of our project using Powerpc
744x running Windriver vxworks 6.x on it instead of a COTS signal
processing library. Although it is little bit straightforward to build a
generic library for x86 platform, there exist a problem in the vxworks
case.

The output of the cygwin is as follows. 
Any idea that to recover the problem will help a lot.

Thanks in advance.
Serkan
