This is a small software program that reads an xml file containing a D-Bus interface following the D-Bus Specifications. The software then outputs a C source file that can be build and linked together with an application to support a particular D-Bus interface, without the hassle of manually programming the GDBus structures or without the potential performance loss or instabilities when parsing the xml file every runtime.
You'll need to have the development glib-2.0 and gio-2.0 packages installed,
then you can compile the C file with a simple make.
After compiling, you can execute the binary with the filename to a D-Bus introspection xml as the first parameter. The C code that it produces is printed to stdout and can be redirected to a file and this file can then be included in your project to be compiled and used. The corresponding header file containing the prototypes of the interface get functions is not included; you'll have to extract the prototypes yourself.
