Bug #11201

Updated by nobu (Nobuyoshi Nakada) over 4 years ago


where it does work (existing package)

~~~ruby
pkg_config("gtk+-x11-2.0") # => ["-pthread", "", "-lgtk-x11-2.0 -lgdk-x11-2.0 -lpangocairo-1.0 -latk-1.0 -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lpangoft2-1.0 -lpango-1.0 -lgobject-2.0 -lglib-2.0 -lfontconfig -lfreetype"]
pkg_config("gtk+-x11-2.0", "version") # => "0.28"
~~~



where it does work (non-existing package)

~~~ruby
pkg_config("wx-bla", "version") # => nil
pkg_config("wx-bla") # => nil
~~~



where it maybe not work (other (pkg)-config program)

~~~ruby
pkg_config("wx", "version") # => "3.1.0"

pkg_config("wx") #either should try to return the same stuff as pkg_config("gtk+-x11-2.0") if possible, or if not return nil
