我有一个带有旧libstdc++的ARM平台。我正在从其他平台交叉编译应用程序，我想使用C++语言的更高级功能，所以我静态地链接我的libstdc++。我正在使用Conan作为包管理器和许多其他动态库，一切都运行得很顺利。
当我尝试添加应用程序的一个全新组件时，问题就出现了，该组件已经在Qt5中编写。突然间，字符串流停止了工作——应用程序没有崩溃，但运营商<lt；(int(重置流中的好比特。
可执行文件上的"objdump-TC"显示，许多libstdc++函数现在被导入(动态链接(，而不是静态链接。
示例：
0000000000000000 DF *UND* 0000000000000000 Qt_5 std::ostream::operator<<(int)
请注意版本"Qt_5"。
我还分解了我的可执行文件，以查看所有对std:：ostream:：operator<lt；(int(确实在调用导入的符号。
当我尝试在使用的g++链接器之前手动解析libstdc++符号时
/usr/bin/aarch64-linux-gnu-ld -r -o out.o main.cpp.o /usr/lib/gcc-cross/aarch64-linux-gnu/7/libstdc++.a
它按预期工作，可执行文件中不再有任何与ostream相关的导入符号，字符串流也正常工作。
关于我的情况有什么想法吗？
下面是CLion执行的链接命令。使用这种组合，应用程序无法工作。

谢谢你的回答。
我找到了解决问题的方法。我需要在lib列表的顶部明确列出标准库的静态版本。这离理想的解决方案还很远，但现在垃圾箱按照我的意愿建造了。
