> > Well yes, you must at least have a compatible version of glibc. This is not specific to Comet, but any native code you build on one system and run on another needs to have compatibility between the build environment and the runtime environment even if the architectures are the same. > > [@parthchandra](https://github.com/parthchandra) Thank you for your response and clarification. I have a question: when you talk about compatibility, do you mean ensuring that the glibc version used in the compilation system matches the glibc version in the runtime system? For example, in my case above, should I make sure both systems use glibc 2.27? > > However, I noticed that the location and name of glibc differ across different systems. In the operating system I am using, Ubuntu (18.04.4 LTS) has `/lib64/ld-linux-x86-64.so.2 -> /lib/x86_64-linux-gnu/ld-2.27.so`, while CentOS 7 has `/lib64/libm.so.6 -> libm-2.17.so`. These seem to follow different patterns; how can I ensure compatibility? @parthchandra After studying the glibc functionality in Linux systems, I now understand the compatibility issue you mentioned. Rust defaults to dynamically linking glibc. Therefore, I just need to ensure that the glibc version on the operating system where the Comet program runs is greater than or equal to the glibc version used during compilation. In my case, this means ensuring that the glibc version on the runtime operating system is >= 2.27. So, when running Comet, it only focuses on the compatibility between glibc versions and does not need to consider the type of operating system. Thank you very much for your help; I appreciate it. -- This is an automated message from the Apache Git Service.
