Then you've caused this problem by trying to mix self-installed software and RPM-packaged software (that presumably isn't from CentOS but some other, incompatible repository). > Whether there is way to install gcc > 4.9 for Centos 7.5? You can install devtoolset-7-gcc-c++ from the Software Collections, but that won't provide a new libstdc++.so and so won't satisfy the dependency either. Why are you trying to install non-CentOS RPMs on CentOS?
