全网首发：Undefined symbols for architecture x86_64: “std::__1::locale::use_facet(std::__1::locale::id&am

Posted 2022-02-18 柳鲲鹏

• 吾是在MAC上编译OpenJDK8出的这个错误。而且这个错误是编译openjdk8u242时出现的。u252就没有这个错误。
• 网上搜索的时候，说增加-lstdc++，或者gcc改为g++。皆无效。
• 具体错误：

clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
