錯誤而編譯GTK +應用程序與g_rename FUNC

我試圖使用g_rename和編譯器給了我奇怪的消息error: called object ‘rename’ is not a function用於行代碼錯誤而編譯GTK +應用程序與g_rename FUNC

if (g_rename(old_file_name, full_new_file_name) == -1)

我不明白爲什麼。

我正在與命令編譯

cc -Wall -g `pkg-config --cflags --libs gtk+-2.0` app.c -o app

gcc版本= GCC（Ubuntu的4.4.1-4ubuntu8）4.4.1

GTK +版本= 2.18.3-1ubuntu

以下是完整的代碼：

首先，您需要在您的機器上安裝libgtk2.0-dev和glibc-dev。在Unix系統上，g_rename默認爲C庫函數rename的別名。您需要#include <stdio.h>才能使用重命名功能而不會出現該錯誤。你看到的實際上是gstdio.h頭文件中的一個bug，它應該包含stdio.h。

這是不是一個錯誤，這是故意的：http://bugzilla.gnome.org/show_bug.cgi?id=166512 – ntd 2010-02-04 14:58:51

不，那是錯誤關於別的東西stdio.h和gstdio.h不一樣 – 2010-02-04 15:04:06

我指的是Matthias的評論：好或壞這是實際的政策。這裏說得更清楚：http://bugzilla.gnome.org/show_bug.cgi?id=566873 – ntd 2010-02-04 19:13:56

我沒有安裝glibc-dev軟件包。在那之後一切正常，但它與消息抱怨：

 
e4.1.c: In function ‘rename_clicked’: 
e4.1.c:138: warning: implicit declaration of function ‘g_rename’

看到我的答案如何解決這個問題。 – 2010-02-04 15:04:41

那麼我包含頭文件「gtk/gtk.h」，「string.h」和「stdio.h」，但我仍然得到警告，這不是致命的，但我不知道意思。而且我也沒有發現在UNIX中使用g_rename作爲重命名的任何參考。 – XoR 2010-02-04 21:05:24
