OK, this describes my observations when trying to compile the git
version of libftdi on FreeBSD. (Before, I've only been using the
stable versions through the FreeBSD ports system, where someone else
"moderates" any build issues and the like.)
First, FreeBSD 8.x (and above) ships with a native libusb that is API
compatible to both, the old 0.1 as well as the 1.0 API. All this is
in libusb.a/libusb.so. However, there is no tool like libusb-config
configure.in relies on.
The FreeBSD port currently removes all the checks for libusb-config
and the libusb version, and then just sets
LIBS="$LIBS -lusb"
(and reruns the auto* tools)
Perhaps there could be a better way for that so FreeBSD doesn't have
to muck around with that?
Second, many of the examples use EXIT_SUCCESS and EXIT_FAILURE, yet
they don't #include <stdlib.h> where these constants are located,
according to the C standard. The patch below fixes that.
