Question

我正在尝试编译一个库，但是在高山linux上出现一些错误。在debian上，一切正常。我安装了

alpine-sdk
linux-headers

这些是错误：

 1. /usr/include/c++/8.3.0/ext/string_conversions.h:63:27: error: 'errno' was not declared in this scope 
_Save_errno() : _M_errno(errno) { errno = 0; }

 2. /usr/include/c++/8.3.0/ext/string_conversions.h:63:27: note: 'errno' is defined in header '<cerrno>'; did you forget to '#include <cerrno>'?

 3. /usr/include/c++/8.3.0/ext/string_conversions.h:84:16: note: 'errno' is defined in header '<cerrno>'; did you forget to '#include <cerrno>'?

       not_supported =     ENOTSUP,

未在此范围内声明errno
