架构armv7的未定义符号：
“STD:：Basic ToSooSt::Puthase< P>您不链接C++标准库。将代码编译为C++（或者ObjaveC++），如果需要的话）链接器会自动合并该库。
 这可能与XCODE不使用正确的C++标准库有关。要修复这个问题，请单击项目，在生成设置下转到项目的目标，搜索称为“C++标准库”的设置。。将其设置为libstdc++或编译器默认值，则不应将其设置为libc++

您需要这样做，因为ScistDeSDK目前还没有运行新的C++ 11标准库，它最近被引入XCODEL中。在不远的将来，版本将用C++ 11编译器编译，并在XCODE中设置为默认的STD库。
 < P>我最近使用了SITDITSDK的3.0.0 RC1版本。对我来说，问题在于没有链接到libc++.dylib库。（构建阶段->将二进制文件链接到库）
您使用的是哪个设备和xcode的哪个版本您使用的是您内部的另一个项目吗？我使用的是SDK是。ScanditSDK版本2。0@H2C03感谢您的快速回复，但我该怎么做呢？在库中添加libc++.dylib减少了一些错误…相反，添加libstdc++.dylib可以删除所有错误。
