Oracle 11g R2 Install To Centos 7.4

I am having problems in installing Oracle 11g R2 to Centos 7.4. Afaik this install should be supported but it is failing. I have found the reason but cannot fix this. So please help me. Problem is this "Error in invoking target 'install' of makefile '/oracle/product/11.2.0/dbhome_1/ctx/lib/ins_ctx.mk'."

Log files tells me "INFO: /usr/lib64/libstdc++.so.5: undefined reference to `memcpy@GLIBC_2.14'". I have googled around trying to find fix for this. Have checked that I have all the needed packages installed but still getting this. Any ideas how to fix this and continue with the install?
