timer - Compile FFTW for ARM -

I am trying to compile the FFTW library to use on the ARM processor, but when compiling the library, Errors are available:

  timer.c: 89: 2: error: #Terror "not defined timer" #Terror "timer is not defined" ^ timer.c: 119: 1: error: Unknown type name 'mytime' static mytime t0 [BENCH_NTIMERS];  

To create a makefile, I use the provided config file, and use it like this:

  ./configure - Enabled-float -with-slo-timer - host = i686-pc-linux-gnu - enabled-single-enabled-neon "cc = arm-axilin-abi-gcc -mcpu = cortex-A9-m ​​float- ABI = softf ""  

What could be the reason for this error? Is there a way to solve them without messing with the code?

Thanks

As far as I know that a cortex-A9 If there is always a timer unit, then I think there is a cycle counter in it, as mentioned in the context of fftw3, you may not use a slow-timer option which is bad anywhere in this case.
