Compiling a libusb example program

  • 772

I recently installed the library libusb by doing this:

sudo apt-get install libusb-1.0-0-dev

I have a directory with examples that looks like this:

penguin@penguin-Satellite-A505:~/Downloads/libusb-1.0.0/examples$ ls -la
total 124
drwxrwxrwx 3 penguin penguin 4096 2011-10-23 11:38 .
drwxrwxrwx 5 penguin penguin 4096 2011-10-23 11:38 ..

penguin@penguin-Satellite-A505:~/Downloads/libusb-1.0.0/examples$

I am trying to compile lsusb.c. Would anyone know how to do it? My OS is Ubuntu 11.1.

Thank You!

11.10

  1. The answer lies in looking at the list of files installed by the libusb-1.0-1-dev package at pakages.ubuntu.com. The source code should read like this:

    #include <libusb-1.0/libusb.h>

    Also the -L switch must be used with the compiler so the libraries can be located at the location installed.

  2. There are makefiles in the directory, so try just running make.

  3. I noticed that Ubuntu 11.04 installs with libusb-1.0, but 11.10 installs with libusb-0.1. Does anyone happen to know more about the apparent backrevving of the lib?

    I tried a few times (unsuccessfully) to manually build and install libusb-1.0 to Ubuntu 11.10, but wasn't able to. Haven't exactly tried the procedure above.
