Just from you nick, I would think that the zedboard in question is a
paralella prototype ?

Do you use the linaro image ?

I compiled it a couple of day ago for that platform.

The linaro image is not a hardfp image AFAIK, it's a softfp eabi.
Also, why would you disable neon ??? the ARM core in the zynq has a
neon unit so you should use it.

I compiled it using those flags :
  -DCMAKE_CXX_FLAGS:STRING="-mfpu=neon"
  -DCMAKE_C_FLAGS:STRING="-mfpu=neon"

I also disabled python support because compiling the SWIG generated
files requires multi-Go of RAM and trying to use swap for it made each
SWIG file take hours to compile ...


Cheers,
