[gdal-dev] GDAL 2.1.0 build error (32 bit, Mac)

[Calogero Mauceri]

Hi all,
I'm trying to build GDAL 2.1.0 in 32 bit on Mac OS X.
I set the following environment variables

export CFLAGS="-arch i386"
export CXXFLAGS="-arch i386"
export CPPFLAGS="-arch i386"
export LDFLAGS="-arch i386"

and then execute

./configure

The build stops with the following error

[...]

Do you have any idea on how to fix this?
It seems a problem related to 32 bit compilation, if I compile GDAL in 
64 bit I do not get any error.

Thanks,
