如何用gtk+-3.0编写程序？

Question

我使用的是ubuntu 12.04中的GTK+-3.0。我试着编译程序，但每次都失败了

apple@ubuntu:~/Downloads$ gcc -Wall -g gtktest.c $(pkg-config --libs --cflags gtk+-3.0) -o gtktest

gtktest.c: In function ‘main’:
gtktest.c:21:3: warning: implicit declaration of function ‘gtk_signal_connect’ [-Wimplicit-function-declaration]

collect2: ld returned 1 exit status

使用另一个命令。

apple@ubuntu:~/Downloads$ gcc -Wall -g gtktest.c $(pkg-config --libs --cflags glib-2.0) -o gtktest
        In file included from /usr/include/gtk-3.0/gdk/gdkapplaunchcontext.h:30:0,
                         from /usr/include/gtk-3.0/gdk/gdk.h:32,
                         from /usr/local/include/gtk-3.0/gtk/gtk.h:32,
                         from gtktest.c:1:
        /usr/include/gtk-3.0/gdk/gdktypes.h:37:19: fatal error: cairo.h: No such file or directory
        compilation terminated.

任何人如何解决这个问题我在过去的4天里一直在努力解决这个问题。有没有人能给我一个合适的解决方案？

Answer 1

gtktest.c:21:3: warning: implicit declaration of function ‘gtk_signal_connect’

您正在编译的代码是为一个非常旧的GTK+版本编写的。如果你想要用GTK+3编译代码，你必须修改代码，更不用说用GTK+2编译了，几乎可以肯定的是，开始使用have会更容易。

/usr/local/lib/libcairo.so: undefined reference to `pixman_glyph_cache_lookup'

我猜你的cairo版本期望的是一个比你链接的版本更新的小精灵:例如，pixman_glyph_cache_lookup()是在小精灵0.27.2中添加的。

最后一个示例尝试在没有GTK include标志的情况下编译GTK代码:这是行不通的。

使用

配置或$(pkg- -lcairo --libs --c cairo)

和-lpixman或-lpixman-1
