我刚刚开始使用libjingle编写一个gtalk聊天机器人。我在让编译器找到XmppPump类调用的XmppClient类时遇到问题。 XmppClient由libjingle在talk / xmpp / xmppclient.h文件中提供,但是由于某种原因,它对我不起作用,并且最近使我感到沮丧。希望你们能够帮助我!

我正在使用libjingle-0.5.1,而我的g++编译器版本是4.4.5。我的操作系统是32位Ubuntu 10.10。

这是我尝试编译代码的方式:
g++ -g -Werror -DPOSIX -DEXPAT_RELATIVE_PATH -DFEATURE_ENABLE_SSL -DHAVE_OPENSSL_SSL_H=1 -I../include -I../misc/libjingle-0.5.1 -I../misc/libjingle-0.5.1/talk/third_party/expat-2.0.1 -I../misc/libjingle-0.5.1/talk/third_party/srtp/include -L../lib -lpthread -lssl -o ../bin/gtalk_bot.bin ../obj/main.o /usr/local/lib/libglog.a ../misc/libjingle-0.5.1/talk/build/dbg/lib/libjingle.a ../misc/libjingle-0.5.1/talk/build/dbg/lib/libexpat.a ../misc/libjingle-0.5.1/talk/build/dbg/lib/libsrtp.a ../misc/libjingle-0.5.1/talk/build/dbg/lib/libxmpphelp.a
这是错误消息:

这是我的目录结构。存在三个libjingle文件夹,因为我正在尝试并尝试不同的方法以查看是否可以解决编译问题。除了将expat-2.0.1 /和srtp /文件夹复制到libjingle / talk / third_party /文件夹之外,libjingle文件夹保持不变。 libjingle-0.5.1 /目录结构与位于此处的svn干线几乎相同:

http://code.google.com/p/libjingle/source/browse/trunk/#trunk

除了我的libjingle-0.5.1文件夹已经被编译。

最佳答案

非常感谢libjingle团队解决了我的问题。显然,静态库排序很重要。我只需要重新排序库即可:

libxmpphelp.a  libjingle.a libexpat.a libsrtp.a

参见“man ld”:



现在,我可以编译我的应用程序了。希望其他人会觉得有用。
