DevOps, CI/CD and Automation

Hi evryone,
I am facing some Linking error which throws up Undefined Symbol errors like .
Undefined first referenced
symbol in file
vector<DPEEDFU>::insert_aux(DPEEDFU*, const DPEEDFU&) ./obj/dpeesel.o
...

I am migrating the code to Sun 5.2 & using -compat=4 for compilation.

On some analysis using nm , I found that the symbols which are flagged as UNDEFINED are in fact getting defined in the temporary objects created in the SunWS_cache directory.

Any suggestion on how to resolve this.
urgent help needed.

Thanks & Regards
shiva
