向ios项目添加firebase框架时的链接器错误

本文介绍了向ios项目添加firebase框架时的链接器错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我一直在尝试将firebase框架添加到我的iOS应用程序中。我按照这里的说明： https://www.firebase.com/docs/ios- quickstart.html 。当我尝试编译我的项目，甚至是Firebase模板项目时，我都会遇到大量的链接器错误。 （如果有人感兴趣，我可以将它们粘贴到这里）但是Firebase框架需要这些框架，我已经确保将它们全部包含在内。 libicucore.dylib CFNetwork.framework Security.framework SystemConfiguration.framework 有没有其他的框架，我想念没有列出？我不知道发生了什么事。感谢您的帮助！ 编辑：这里是错误 架构i386的未定义符号：std :: 1 :: basic_string，std :: __ 1 :: allocator> :: compare（char const *）const，引用自： leveldb :: VersionSet :: Firebase（version_set.o）中的Recover（）std :: _ 1 :: _vector_base_common :: __ throw_length_error（）const ，在Firebase（db_impl.o）中引用： void std :: _ em> 1 :: vector> :: _push_back_slow_path（leveldb :: Iterator * const& amp;

When I try to compile my project, or even the firebase template project I get a ton of linker erros. (I could paste them here if someone is interested but it's a lot of text) The firebase framework requires these frameworks and I've made sure to include them all.libicucore.dylibCFNetwork.frameworkSecurity.frameworkSystemConfiguration.frameworkIs there some other framework I'm missing that wasn't listed? I have no idea what's going on.

We pushed a new version today that added a new dependency on libc++.dylib If you add that, it should build.Note that there's also an issue with the current build that prevents building for arm64. Given that, you may want to just use the previous build: https://cdn.firebase.com/ObjC/Firebase.framework-1.0.9.zipElse wait a day or so and we'll get the latest build straightened out.Sorry for the inconvenience! 这篇关于向ios项目添加firebase框架时的链接器错误的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
