cannot install opera 42 on Centos 6

[tigrehiro]

I am using Centos 6.8, kernel 2.6.32-642.13.1.el6.x86_64, which Opera 12 works fine. But when I tried to install Opera 42 by the rpm package. It gave a lot of error below:

rpm -ivh opera.rpm warning: opera.rpm: Header V4 RSA/SHA512 Signature, key ID f6d61d45: NOKEY error: Failed dependencies: libnotify.so.4()(64bit) is needed by opera-stable-42.0.2393.517-0.x8664 libstdc++.so.6(CXXABI1.3.5)(64bit) is needed by opera-stable-42.0.2393.517-0.x8664 libstdc++.so.6(GLIBCXX3.4.14)(64bit) is needed by opera-stable-42.0.2393.517-0.x8664 libstdc++.so.6(GLIBCXX3.4.15)(64bit) is needed by opera-stable-42.0.2393.517-0.x86_64

I tried to install libstdc++.i686. It is installed ok, but the Installing still gave me the same error.

I cannot find libnotify.so.4 for CentOS 6 anywhere. They have it for CentOS 7 but not for the 6 version. What dependency should I install ?

I tried: yum whatprovides libnotify.so.4

It returned "No matches found"

Please suggest.
