问题描述
我已经从
我正在尝试使用以下命令对其进行编译
I am trying to compile it using the command
gcc pkg-config --libs --cflags dbus-1 dbus-glib-1-2 glib-2.0 -o dbus-ping-pong dbus-ping-pong.c
但是我收到以下链接器错误
But i am getting the below linker errors

有人可以帮助我解决此问题吗？
Can anyone plz help me to resolve this issue ?
推荐答案
gcc- o dbus-ping-pong dbus-ping-pong.c pkg-config --libs --cflags dbus-1 dbus-glib-1 glib-2.0
gcc -o dbus-ping-pong dbus-ping-pong.c pkg-config --libs --cflags dbus-1 dbus-glib-1 glib-2.0
以下注释可以最好地说明问题（从某些论坛复制）
The following comment best explains the problem(Copied from some forum)
以正确的顺序列出库非常重要。当gcc扫描命令行时，它会提取到目前为止所需的内容。每次看到对象时，都会将其添加到程序中。每次看到库时，它只会拉入此时所需的对象。您应该始终在对象之后列出库。
"It's very important to list libraries in the correct order. As gcc scans the command line, it pulls in what it needs so far. Each time it sees an object, it adds it to the program. Each time it sees a library, it pulls in only the objects that it needs at that point. You should always list libraries after the objects"
pkg-config程序用于检索有关系统中已安装库的信息。它通常用于编译和链接一个或多个库。
The pkg-config program is used to retrieve information about installed libraries in the system. It is typically used to compile and link against one or more libraries.
如果仅给出pkg-config --libs --cflags dbus-1 dbus-glib-1 glib-2.0不带任何单引号或双引号在命令行上它扩展为
-pthread -I / usr / include / dbus-1.0 -I / usr / lib / i386-linux-gnu / dbus-1.0 / include -I / usr / include / glib-2.0 -I / usr / lib / i386-linux-gnu / glib-2.0 / include -pthread -ldbus-glib-1 -ldbus-1 -lpthread -lgobject-2.0 -lgthread-2.0 -lrt -lglib-2.0
因此它具有目标文件后提到的所有include和Dependenci库
If you give only pkg-config --libs --cflags dbus-1 dbus-glib-1 glib-2.0 without any single or double quotes on command line it expands to-pthread -I/usr/include/dbus-1.0 -I/usr/lib/i386-linux-gnu/dbus-1.0/include -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -pthread -ldbus-glib-1 -ldbus-1 -lpthread -lgobject-2.0 -lgthread-2.0 -lrt -lglib-2.0so it has all the includes and dependenci libs mentioned after object file
