Question

我一直在使用docker映像进行c ++编译。它基于Ubuntu 18.04。当我尝试在某些Ubuntu 16系统上运行时，出现以下消息：

/lib/x86_64-linux-gnu/libm.so.6：未找到版本“ GLIBC_2.27”

我将在下面发布完整的ldd输出。我喜欢使用较新的编译器。我宁愿不使用较旧的Linux基本映像进行编译（但如有必要，我会这样做）。我静态链接了大多数库，但是我还没有静态链接glibc。许多网络资源都建议不要这样做。有什么办法可以告诉我的较新的编译器（gcc 7.3）不需要较新的glibc？ ldd -v输出：

Answer 1

您需要针对较早的glibc版本进行构建。开箱即用的发行版很少（如果有的话）支持。目前唯一可行的方法是建立在较旧的发行版上。

某些支持周期较长的发行版提供了不需要较新系统编译器的较新GCC版本（例如CentOS和Red Hat Enterprise Linux可用的Developer Toolset）。

Answer 2

我遇到了同样的问题。

/lib/i386-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by your_lib.so)

在互联网上搜索后，我发现了一些可能有用的链接。

静态链接： 与-static链接。参见How can I link to a specific glibc version?

使用docker：参见Can docker solve a problem of mismatched C shared libraries?

专有解决方案：请参见https://github.com/wheybags/glibc_version_header

我决定遵循第一个。因此，我为 your_lib.so 创建了一个静态库，并将其与我的二进制文件静态链接。
