     struct __timepunct_cache : public locale::facet

以上是我的构建日志中的第一个错误。

我没有尝试自己编译 glibc/gcc，而是通过 yum 安装的。

我发现的一件可疑的事情是：

$ ll /usr/include/c++/
total 4
drwxr-xr-x. 12 root root 4096 Dec 17 14:16 4.8.2
lrwxrwxrwx   1 root root    5 Dec 17 14:16 4.8.5 -> 4.8.2
$

yum 只显示了 1 个版本的 gcc：

$ yum info gcc-c++

知道如何验证 /usr/include/c++/4.8.2 中的标头确实来自 4.8.5 包吗？

提前致谢。

PS我认为glibc可能无关紧要，但这里是信息：

目录的符号链接4.8.2没什么好担心的，Red Hat Enterprise Linux（以及 CentOS）上的 libstdc++ 头文件这样排列是正常的。

gcc --version将告诉gcc您路径中可执行文件的版本。

rpm -q libstdc++-devel将告诉您拥有 C++ 标准库头文件的包的版本。

rpm -ql libstdc++-devel将列出该软件包安装的文件，其中将包括以下文件/usr/include/c++/4.8.2

rpm --verify libstdc++-devel将通过用其他东西替换它们来检查您是否没有弄乱 C++ 标头。

该错误更令人担忧，这意味着您搞砸了。我的猜测是它在from [...omitted by myself as it is irrelevant]部分中，这实际上可能非常相关。std::locale应该声明<bits/locale_classes.h>其中包含 before <bits/locale_facets_nonio.h>，所以如果没有声明，我的猜测是你有一些头文件定义_LOCALE_CLASSES_H并阻止标准库头文件被读取。不要定义以下划线开头的包含保护，它们是保留名称。

由于您使用的是Linux，您可以尝试

 ldd --version
