Try installing GCC library using zypper:

zypper install libgcc_s1-4.7.2_20130108-0.17.2.x86_64.rpm
zypper install libstdc++6-4.7.2_20130108-0.17.2.x86_64.rpm
rpm -qa |grep gcc (For querying, if installation is done)

 

Zypper is the native command-line interface of the ZYpp package manager for installing, removing, updating and querying software packages of local or remote (networked) media. Its graphical equivalent is the YaST package manager module. (From Wiki)
