Error in invoking target 'links proc gen_pcscfg procob rtsora' of makefile

boy o boy, if you are getting error during ORACLE client installation especially on Redhat Linux 5.5, and the error is somewhat like:

"Error in invoking target 'links proc gen_pcscfg procob rtsora' of makefile '/soft/oracle/app/cliente/product/11.2.0/precomp/lib/ins_precomp.mk'."


or by any means you are seeing something "rtsora" in error message it means you must unset your environment variables especially regarding to COBOL, because ORACLE does mind these variables setting before actually ORACLE's client installation.

we had the same issue at our ORACLE ETPM (Enterprise Taxation and Policy Management) server, because we actually set our ~/.bash_profile and declared $COBDIR before even actually installing COBOL OR ORACLE client.

Solution:

Prior to doing the Client install:
1.  Unset the following variables:
COBDIR, COBLIB, COBPATH, LD_LIBRARY_PATH, ORACLE_PATH

2.  Remove the Cobol and Oracle client bin directories from your PATH variable:

Reinstall on clean Client Home.

Cheers
