R12.1.2 Relinking issues after 64bit Migration

We have a large R12 upgrade coming up on the horizon.  Upgrading to R12.1.2, 11gR2 and migrating to 64bit.   As part of the post 64bit migration you have to relink the application programs.  A number of modules wouldn’t relink tho:

Example:

g++: /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog/6.2/libschedule.a: No such file or directory
g++: /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog/6.2/libsolveriim.a: No such file or directory
g++: /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog/6.2/libconcertext.a: No such file or directory
g++: /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog/6.2/libsolver.a: No such file or directory
g++: /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog/6.2/libconcert.a: No such file or directory
make: *** [/u01/TEST/apps/apps_st/appl/eng/12.0.0/bin/ENCACN] Error 1
Done with link of eng executable 'ENCACN' on Tue Oct 19 15:32:10 EDT 2010

Relink of module "ENCACN" failed.


I opened up an SR with oracle but continued to research the problem.   I didn't see anything on Metalink for R12, Google same result.   I searched the entire filesystem to see if the libraries existed elsewhere but no luck
.
I noticed a zip file /u01/TEST/apps/apps_st/appl/sht/12.0.0/lib/ilog62lib.zip and listed the contents to see what was in it.  Here is a snip:

[oravis@myserver lib]$ unzip -l ilog62lib.zip

The libraries adrelink was looking for.  I extracted the files, changed to the LINUX directory, moved the files up to the parent directory,  relinked (via adadmin) and it completed successfully.

----

Looking back on the problem, its strange I didn't encounter it before.   This environment is a copy of an existing R12.1.2 32bit environment.   The only thing i'm changing is migrating it to 64bit.   So I should have hit these relinking issues before.   I checked the source environment and the libraries are indeed there!  

The zip file contains the libraries for a number of platforms, AIX, HPUX, etc.   So the only thing I can think of is that since i'm doing a platform migration, these libraries get removed to make sure the proper ones are used.  However, it doesn't continue and extract the correct libaries from the zip file.

Im experiencing the exactly same issu but I could not find the ilog62lib.zip.

Do you know how to generate it?
