文件夹结构
执行命令
node-gyp configure
node-gyp build
假设没有安装对应的库/路径找不到。中间会出现头文件找不到的错误；
笨拙的解决方法。在build以下的Makefile中加入
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/gtkmm-3.0/include -I/usr/include/atkmm-1.6 -I/usr/include/atk-1.0 -I/usr/include/libnotifymm-1.0
上述的库是依据错误提示进行安装的
Javascript測试代码
var notify = require("./build/Release/node_gtknotify");
var notification = new notify.notification();
notification.title = "Notification title";
notification.icon = "emblem-default"; // see /usr/share/icons/gnome/16x16
notification.send("hello,world");
注意，执行时可能有错误提示：**符号找不到，这是由于没有加入对应的共享链接库
解决方法：在build/node_gtknotify.target.mk中加入
LIBS := -lglibmm-2.4 -lnotify -lnotifymm-1.0
执行效果
