Introduction to libgusb

The libgusb package contains the GObject wrappers for libusb-1.0 that makes it easy to do asynchronous control, bulk and interrupt transfers with proper cancellation and integration into a mainloop.

Installation of libgusb

Install libgusb by running the following commands: 

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release -Ddocs=false .. &&
ninja

If you have Gi-DocGen-2023.1 installed and wish to build the API documentation for this package, issue: 

sed "/output: 'libgusb'/s/'\$/-0.4.5'/" -i ../docs/meson.build &&
meson configure -Ddocs=true                                    &&
ninja

To test the results, issue: ninja test.

Now, as the root user: 

ninja install

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Ddocs=false: Allow building this package without Gi-DocGen-2023.1 installed. If you have Gi-DocGen-2023.1 installed and you wish to rebuild and install the API documentation, a meson configure command will reset this option.
