问题描述
我正在尝试在一些较旧的32位RedHat发行版上运行新编译的二进制文件.
二进制文件是在运行libc v2.12的CentOS 32位VM上编译的(不是++).
RedHat抱怨libc版本:
I am trying to run a newly compiled binary on some oldish 32bits RedHat distribution.
The binary is compiled C (not++) on a CentOS 32bits VM running libc v2.12.
RedHat complains about libc version:
error while loading shared libraries: requires glibc 2.5 or later dynamic linker由于我的程序非常简单，因此很可能没有使用libc中的新功能.
有没有办法降低libc版本要求
Since my program is rather simplistic, It is most likely not using anything new from libc.
Is there a way to reduce libc version requirement
推荐答案
好吧，然后，尝试在优雅和蛮力之间找到平衡，我下载了一个与目标内核匹配的 VM ，因此进行了修复库问题.
整个过程(下载+ yum install gcc)用了不到30分钟.
参考:虚拟机，内核版本映射表
Ok then, trying to find some balance between elegance and brute force, I downloaded a VM matching the target kernel version, hence fixing library issues.
The whole thing (download + yum install gcc) took less than 30 minutes.
