CentOS 7 development computer. How to get compiled C++ program to work on CentOS 6? Gives errors of mismatch of versions of libraries...

Answer 1

There are several options
1) Link the application with the -static flag. You will only have to use static third party libraries for this.
2) Build a cross-compiler in which build the same version of libc as in centos 6, then it will be possible to link with statics only c++ and gcc runtimes ( libstdc++.a, libgcc.a) through the flags -static-libgcc and -static- libstdc++
On the seven, glibc is older, and it has only top-down compatibility. Resolve the issue with her first.
3) Start a build server on 6-ke, let the release builds build there, build the compiler you need, the problem with glibc will disappear by itself. Well, yes, link runtimes with statics.

Answer 2

Well, it's easier to put a virtual machine with CentOS 6 to the developer.

Answer 3

1. First, show the output of ld
2. Then the output of objdump -T
If it is impossible to rebuild, transfer the necessary libraries to the target platform and make a sendbox.
