Not able to compile .pcc (Pro*C++) file

Hello,

I use Omniworks build environment for compiling proc++(filename.pcc) files which would result in .filename.cc. I am not able get these files due some misplacement in environment... Could anyone explain the environment variable linked to it .. I know few like LIB_PATH,LD_LIBRARY_PATH and ORACLE_HOME (which contains proc precompiler)..
