Fedora下搭建gtk开发环境（2014-12-20）

本周在学习gobject-introspection，很多优质的blog都是从代码讲起的。本想了解一下gi的原理，看着看着发现没有自己跑例程就看不下去了。因此打算自己搭建一个平台测试一下相关代码。由于gi是gtk的升级版本，网络上可供参考的环境搭建多是有关gtk的，所以就有了这个题目“Fedora下搭建gtk开发环境”。

1.搭建过程

（1）在Fedora平台上搜索并安装gtk3.0-dev软件包（Ubuntu等平台只是更换命令即可）

[root@localhost ~]# yum search gtk 3.0 dev

已加载插件：langpacks, refresh-packagekit

......

gtk-vnc2-devel.x86_64 : Development files to build GTK3 applications with

: gtk-vnc

gtk3-devel.i686 : Development files for GTK+

gtk3-devel.x86_64 : Development files for GTK+

gtk3-devel-docs.x86_64 : Developer documentation for GTK+

......

sugar-toolkit-gtk3-devel.x86_64 : Invokation information for accessing

: SugarExt-1.0

全名和简介匹配 only，使用“search all”试试。

dev软件包是开发所需头文件的集合，需要下载dev包。

可以看到gtk3-devel.x86_64是我需要的开发包（均为x86_64，因为是在64位机上，32位选i686）

[root@localhost ~]# yum install gtk3-devel.x86_64

（2）运行`pkg-config --cflags --libs gtk+-3.0`测试是否通过（Ubuntu可以直接通过）

现在看不到了，只安装gtk+-3.0会报错。因为有包依赖关系。

（3）报错需安装相关的软件包pango-devel和atk-devel（同样x86_64）

[root@localhost ~]# yum install pango-devel.x86_64

[root@localhost ~]# yum install atk-devel.x86_64

（4）继续测试`pkg-config --cflags --libs gtk+-3.0`

[root@localhost ~]# pkg-config --cflags --libs gtk+-3.0

-pthread -I/usr/include/gtk-3.0 -I/usr/include/at-spi2-atk/2.0 -I/usr/include/gtk-3.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/harfbuzz -I/usr/include/pango-1.0 -I/usr/include/atk-1.0
-I/usr/include/cairo -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libdrm -I/usr/include/libpng16 -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/libpng16 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -lgtk-3 -lgdk-3 -lpangocairo-1.0
-lpango-1.0 -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0

测试通过。

2.测试环境

编写简单程序（copy的官方gtk2里example）

[root@localhost arrow]# cat arrow.c

#include <gtk/gtk.h>

/* Create an Arrow widget with the specified parameters
* and pack it into a button */
GtkWidget *create_arrow_button( GtkArrowType  arrow_type,
GtkShadowType shadow_type )
{
GtkWidget *button;
GtkWidget *arrow;

button = gtk_button_new ();
arrow = gtk_arrow_new (arrow_type, shadow_type);

gtk_container_add (GTK_CONTAINER (button), arrow);

gtk_widget_show (button);
gtk_widget_show (arrow);

return button;
}

int main( int   argc,
char *argv[] )
{
/* GtkWidget is the storage type for widgets */
GtkWidget *window;
GtkWidget *button;
GtkWidget *box;

/* Initialize the toolkit */
gtk_init (&argc, &argv);

/* Create a new window */
window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

gtk_window_set_title (GTK_WINDOW (window), "Arrow Buttons");

/* It's a good idea to do this for all windows. */
g_signal_connect (G_OBJECT (window), "destroy",
G_CALLBACK (gtk_main_quit), NULL);

/* Sets the border width of the window. */
gtk_container_set_border_width (GTK_CONTAINER (window), 10);

/* Create a box to hold the arrows/buttons */
box = gtk_box_new (FALSE, 0);
gtk_container_set_border_width (GTK_CONTAINER (box), 2);
gtk_container_add (GTK_CONTAINER (window), box);

/* Pack and show all our widgets */
gtk_widget_show (box);

button = create_arrow_button (GTK_ARROW_UP, GTK_SHADOW_IN);
gtk_box_pack_start (GTK_BOX (box), button, FALSE, FALSE, 3);

button = create_arrow_button (GTK_ARROW_DOWN, GTK_SHADOW_OUT);
gtk_box_pack_start (GTK_BOX (box), button, FALSE, FALSE, 3);

button = create_arrow_button (GTK_ARROW_LEFT, GTK_SHADOW_ETCHED_IN);
gtk_box_pack_start (GTK_BOX (box), button, FALSE, FALSE, 3);

button = create_arrow_button (GTK_ARROW_RIGHT, GTK_SHADOW_ETCHED_OUT);
gtk_box_pack_start (GTK_BOX (box), button, FALSE, FALSE, 3);

gtk_widget_show (window);

/* Rest in gtk_main and wait for the fun to begin! */
gtk_main ();

return 0;
}

[root@localhost arrow]# gcc arrow.c -o arrow.o `pkg-config gtk+-3.0 --cflags --libs`

[root@localhost arrow]# ./arrow.o
