带有静态库（.a）和动态库（.dylib）的重复符号

Question

在我的iOS项目中，正在使用库libbaidumapapi.a和libPayPalMPL.a。

该项目可以正确构建，但它在运行时发出异常信号。

在调试的问题，我发现它的原因是因为库libPayPalMPL.a调用库内libbaidumapapi.a的XMLFreeDoc功能，但应该调用里面xml2动态库的xmlFreeDoc释放功能。

我没有这两个库的源代码。当我检查libbaidumapapi.a时，发现它与minixml.o和deflate.o存档与XMLFreeDoc和deflate可能与libPayPalMPL.a冲突。

libPayPalMPL.a依赖于两个动态库的库：xml2和zlib。

我可以修复这个崩溃问题吗？我已在libbaidumapapi.a之前使用force_load。

以下是link命令，以防万一需要。

MPL已被弃用。相反，建议您使用iOS SDK：https://github.com/paypal/PayPal-iOS-SDK
