Thank you both very much, it worked like a charm.
I post here some instruction that may be useful to somebody else:
To generate the config.h with Waf you have to define your constants in
the configure method of the main wscript:
conf.define('PACKAGE', APPNAME)
conf.define('DATADIR', os.path.join(conf.env['PREFIX'], 'share', APPNAME))
...
and then write the file (at the end of configure method):
conf.write_config_header("config.h")
Then in the wscript_build file (or build method of wscript file,
depending on your file layout) inside the sources directory you simply
have to add a line specifying the location of your config.vapi file
obj.vapi_dirs = '../vapi'
and add the "config" package to the packages string
obj.packages = 'gtk+-2.0 glib-2.0 gio-2.0 config'
That was enough for me to make it work.
If you want to see the full sources they're here:
