Requires: gcc = 4.4.7-11.el6

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

solve

Delete the dependencies of gcc, cpp, libgomp, etc. first, and then reinstall gcc-c++ directly, let it automatically install the correct version of its dependent gcc, cpp, libgomp

yum remove gcc cpp libgomp

yum install gcc-c++
