Bug #11201

Updated by nobu (Nobuyoshi Nakada) about 5 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
