Need help cross-compiling libusb with arm-linux-gcc

Hi, I'm new in cross-compiling and I need to compile libusb to be used in a
software portable on arm architecture.

I downloaded libusb-1.0.8 from http://sourceforge.net/projects/libusb/
and arm-linux-gcc-3.3.2.tar.bz2 from
http://ftp.gwdg.de/linux/handhelds/projects/toolchain/

I extracted arm toolchain and added the subdirectory /bin/ to my PATH.
I tryed to cross-compile a simple hello_world.c

arm-linux-gcc hello_world.c

And it worked fine.
After that, I tryed to cross compile libusb. I moved into libusb directory
and did:

./configure --host=arm-linux
make

after launching make, it stopped with the following error:

os/linux_usbfs.c: In function `find_monotonic_clock':
os/linux_usbfs.c:206: error: `CLOCK_MONOTONIC' undeclared (first use in
this function)

I've no idea what's talking about. Am I doing something wrong in
cross-compiling? Or do I miss some tools?
I'm sorry for my bad english and I thank you very much, I need this library
for my thesis at University, nobody of my docents or mates can help me
about cross-compiling.

Perhaps, if you either post the script or list the commands you are using
to do this someone might be able to help.

It appears you have not included a library that is needed.

Why are you not using the toolchain that comes on the CD or from the
downloads page?

I followed the steps showed in this post:

http://www.friendlyarm.net/forum/topic/2289

$ ./configure --host=arm-linux --prefix=/home/abhinit/libusb/install
$ make
$ make install

but when I launch the first "make" command it shows me that error about
CLOCK_MONOTONIC.

I used the toolchain downloaded from the ftp link above provided me by my
docent and I don't know where I should download it other than there.

I downloaded from this site, now everything works fine!

I need help on cross compiling libusb to ARM Cortex-M7 microcontroller. Can
anybody help me out?
