error while loading shared libraries: libusb-0.1.4
Hi. I have two USB problems on two different machines.
On my main desktop, I'm trying to run a demo application for a USB fingerprint reader. However, it is trying, and failing, to find libusb. The error message looks like this:
$ ls
README vf_gtk_demo vfinger_linux.zip
[ross@staff-pc01 VERIFINGER]$ ./vf*demo
./vf_gtk_demo: error while loading shared libraries: libusb-0.1.4: cannot open shared object file: No such file or directory
$
The readme suggests (in terms of accessing harware) running as root. However, as expected, I get the same error message while running as root.
In /usr/lib I have the following libusb files (note: libusb-0.1.4.so is an additional symbolic link I created while trying to solve this).
$ ls -l libusb*
lrwxrwxrwx 1 root root 15 Nov 10 09:31 libusb-0.1.4.so -> libusb-0.1.so.4
lrwxrwxrwx 1 root root 19 Jun 23 2003 libusb-0.1.so.4 -> libusb-0.1.so.4.1.1
-rwxr-xr-x 1 root root 25004 Jan 24 2003 libusb-0.1.so.4.1.1
-rw-r--r-- 1 root root 27798 Jan 24 2003 libusb.a
-rwxr-xr-x 1 root root 704 Jan 24 2003 libusb.la
lrwxrwxrwx 1 root root 19 Jun 23 2003 libusb.so -> libusb-0.1.so.4.1.1
lrwxrwxrwx 1 root root 9 Nov 5 12:39 libusb.so.1 -> libusb.so

I've given the output of ldd vf_gtk_demo down the bottom of this email. Summary: it doesn't find libusb.
Can anyone suggest what the problem might be?
Cheers,
