我的公司正在为iPhone开发一个使用SDK 4.1的应用程序。
为此，我们有3个项目依赖级别，我们的主要应用程序“CSM”链接到我们的SDK“csm-sdk”（在libsrc_csmsdk.a中），然后csm-sdk链接到我们的XMLRPC库（“libXMLRPC.a”）。
在为设备编译csm-sdk时，它包括所有ObjC类的定义和两个oue XMLRPC库的C函数。
然后当CSM链接时，它报告同一库文件中的重复对象。
我们在所有级别上都使用-all_load和-ObjC进行链接。
我有另一个在SDK 3.2上执行类似操作的项目，一切正常...而这个在4.1上作为模拟器构建一切正常，只是设备失败了。有人遇到过类似的问题吗？
以下是更多详细信息。
谢谢！
