/libusb4java

The native JNI library used by usb4java

Primary LanguageCMIT LicenseMIT

This is the source code of the JNI wrapper for libusb. usb4java already includes prebuilt libraries for the following platforms:

  • linux-x86
  • linux-x86-64
  • linux-arm
  • linux-aarch64
  • win32-x86
  • win32-x86-64
  • darwin-x86-64
  • darwin-arm-64

If you need the library on an other platform then you can easily compile it yourself. On a Unix-compatible operating system you only need the Java JDK, an up-to-date libusb library version, the GNU C compiler and cmake. When everything is correctly installed then you should be able to build the library with the following commands:

$ mkdir build
$ cd build
$ cmake ..
$ make

When compilation was successful then you can find the library in the build/src directory.

usb4java searches for the library in the CLASSPATH directory org/libusb4java/<OS>-<ARCH>/. On a 32 bit x86 linux machine for example the directory name is org/libusb4java/linux-x86. Usually you can find the required name in the exception thrown by usb4java when it does not find the required library.
