[fprint] How to cross compile libfprint for ARM-Linux

[Rafael Toledo]

Hi! I successfully compiled libfprint in a project last year for a ARM9
system. The big issue was to compile the dependencies. For this reason, I
could only run version 0.0.6, because I couldn't compile NSS (required for
later versions). Well, I used buildroot to compile all dependencies needed
by libfprint, such openssl, libusb and glib2. After all, I used the
generated toolchain to compile libfprint using the following steps:

(for some reason, the RANLIB flag can't find a relative path, so I used the
full path as a parameter for this flag)
$ AR=arm-linux-ar CC=arm-linux-gcc CXX=arm-linux-g++
RANLIB=/home/rafael/buildroot/output/host/usr/bin/arm-linux-ranlib
./configure --host=arm-linux --target=arm-linux
--prefix=/home/rafael/buildroot/libfprint

$ make

$ make install

After all, it generated libfprint.so, libfprint.so.0 and libfprint.so.0.0.0
that I copied to the ARM9 Linux system.
