I\'m trying to set up libusb API on my OS. I downloaded libusb api on libusb.org. I followed the standard installation procedure:
cd into directory
./configu
I don't use Eclipse C/C++ but I am pretty sure the reason is the same that I faced some while ago when setting up a C project in Netbeans.
It's not enough to have the #include in your code and the library at the right location - you also have to tell Eclipse where to look for them and how to use them. This turorial shows you how to set it up in Eclipse.
