假設(shè)沒(méi)有安裝對(duì)應(yīng)的庫(kù)/路徑找不到。中間會(huì)出現(xiàn)頭文件找不到的錯(cuò)誤；

笨拙的解決方法。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

上述的庫(kù)是依據(jù)錯(cuò)誤提示進(jìn)行安裝的

Javascript測(cè)試代碼

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，執(zhí)行時(shí)可能有錯(cuò)誤提示：**符號(hào)找不到，這是由于沒(méi)有加入對(duì)應(yīng)的共享鏈接庫(kù)

解決方法：在build/node_gtknotify.target.mk中加入

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

執(zhí)行效果

總結(jié)
