'Versions of GLIBC

I have created c++ application in Ubuntu machine. I have copied binary to Centos machine. Got error:

/usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found

I decided to check which versions of glibc I have in my machines with help of ldd --version command:

Ubuntu: 2.23
Centos6.9: 2.12

Why CentOS cmplains regarding GLIBCXX_3.4.21, while Ubuntu owns glibc version 2.23?

The symbols like GLIBCXX_3.4.21 are generated by the compiler to mark which version of the C++ library that the compilation was used with (in particular, non-inline functions called from header-files & template functions). This is the libstdc++ library, not glibc.

The version that you are looking for is your libstdc++ - and this is one of the interesting problems with C++, the template library tends to change every now and again, so a function may be declared as unsigned int func(), and later someone decides to change it to size_t func(). No difference in 32-bit machines, but for 64-bit machines it DOES make a difference, and using the "wrong" version will lead to problems with the size of the return value.

There are a few different solutions (and this is not a complete list):

  1. Make sure you use the same version of libstdc++ on both machines.
  2. Compile the code on the target machine.
  3. Use static libstdc++

This a great - I used the -static option in the link and it solved by problem also.
