Error compiling, duplicate member on header, endian.h

Question

I am trying work with FingerPrinter SDK, it shows an example to runs it on linux, i run it on linux cuz its more customizable than windows, well i followed all instructions included to build and compile, but i get this error. These SDK uses libusb library and some usb rules, both are perfectly installed and allowed. Hope get some help.

this is the complete pack where you can find all codes and readmes.

Dowload code!

The stdlib.h is including the endian.h from your (or the SDK's) source code instead of the one from the standard include files, thus __BYTE_ORDER is never defined. Find the conflicting endian.h file and rename it. Or remove -I compilation flag from your tool chain.
