If the corresponding Library/path is not installed, the header file cannot be found;

Clumsy solution, add in Makefile under build

CXXFLAGS + =-I/usr/include/glibmm-2.4-I/usr/lib/x86_64-linux-gnu/glibmm-2.4/include-I/usr/include/glib-2.0-I/usr/lib/x86_64-linux-gnu/glib -2.0/include-I/usr/include/sigc ++-2.0-I/usr/lib/x86_64-linux-gnu/sigc ++-2.0/include-I/usr/include/giomm-2.4 -I/usr/include/gdkmm-3.0-I/usr/lib/x86_64-linux-gnu/gdkmm-3.0/include-I/usr/include/pangomm-1.4-I/usr/lib/x86_64-linux-gnu/pangomm-1.4/include -I/usr/include/gtk-3.0-I/usr/include/pango-1.0-I/usr/include/cairo-I/usr/include/gdk-pixbuf-2.0-I/usr/include/cairomm-1.0 -I/usr/include/freetype2-I/usr/include/gtkmm-3.0-I/usr/lib/x86_64-linux-gnu/include-I/usr/include/gtkmm-3.0-I/usr /include/atk-1.0-I/usr/include/libnotifymm-1.0

 

The above libraries are installed according to the error prompt

 

Javascript test code

Var require y = require (./Build/Release/node_gtknotted);

Var notification = new every Y. notification ();

Notification. title = Notification title;

Notification. icon = emblem-default; // see/usr/share/icons/gnome/16x16

Notification. send (hello, world );

 

Note: The ** symbol cannot be found because the corresponding shared link library is not added.

 

 

Solution: In build/node_gtknotify.target.mk, add

LIBS: =-lglibmm-2.4-lnotify-lnotifymm-1.0
