Right. As I said in my previous email, once you fix the headers, you'll need to fix the libraries as well. It can find usb.h now (header), but I'm guessing it installed the libraries in /usr/lib/libusb-1.0 as well, which is why it can't find the libraries either. So your instinct here: > I did try a few other things including moving everything in > /usr/lib/libusb-1.0 > to /usr/lib and also tried to symlink libusb1.0.0.dylib to libusb.dylib > but at > that point I was mostly flailing helplessly. Was correct. These were the files it was looking for. Moving them should have worked. HOWEVER, I've never tried building against libusb 1.0. Every major linux distro is still shipping 0.1 by default, and that's what I've always linked against. My guess here is that libusb 1.0 is putting itself in a subdirectory to allow for both versions to be installed along side one another. > I don't understand what 'usb_init in -lusb' means or what it's checking for, > even after looking into the configure and Makefiles, but I'll attribute > that to > being a noob, so I don't really know how to fix this problem. That means it's compiling a small test program using "-lusb" (telling the linker to link in libusb) and trying to call the usb_init() function. This is how it can tell if the libusb on the system is there and functioning.
