Fix Steps:- I face this error in TDI V7.2 on centos vm machine while running TDI solutions.
I found resolution that libstdc++ library was missing.
Complete the below steps

1) Install the below library
yum install libstdc++*

2) Uninstall TDI V7.2
3 ) Again install TDI V7.2

Now TDI is executing solution in environment.
hope this help!!
