I have installed the GLIBCXX_3.4.21 but it always reports libstdc++.so.6(GLIBCXX_3.4.21)(64bit) is needed during the RPM install

Hi,
I have a question which really blocked me a long time, many thanks for any help!


1.     When I install a RPM package, it always reports "libstdc++.so.6(GLIBCXX_3.4.21)(64bit) is needed by".
# rpm -ivh cnet-c-0.1.0-18.9.x86_64.rpm
error: Failed dependencies:
        libstdc++.so.6(GLIBCXX_3.4.21)(64bit) is needed by cnet-c-0.1.0-18.9.x86_64


2.     Based on the search, I use following commands to check the dynamic libstdc++.so installation.
The version to GLIBCXX_3.4.22 has been installed and the libstdc++.so.6 points to libstdc++.so.6.0.22.
/usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.22





Any suggestions how I should do to solve the dependency issue? And whether I need to downgrade the GLIBCXX_3.4.22 to GLIBCXX_3.4.21?

Thanks very much for any help!
