Issues faced while upgrading Oracle Applications (E-Business Suite) from 11i to R12.2

 Issue# 10:

Relinking MT executables failed.

 

Solution:

To determine which gcc executable is used by the application run the following:

As the user who is facing the issue run:

[apdpro@dbmig bin]$ which gcc

/u03/dproora/8.0.6/bin/gcc

[apdpro@dbmig bin]$

 

To check for gcc version used:

[apdpro@dbmig ~]$ gcc -v

From root check the version of gcc under /usr/bin:

-          From the above it seems that the gcc version running from ORALE_HOME is higher than the required version as per    How to Deal with Relink, make Failed on Linux ? ERRORS : bin/sh: /usr/bin/cc: cannot execute binary file. or undefined reference to `dl_iterate_phdr@GLIBC_x.x.y'....make: *** [f60run] Error 126" (Doc ID 833732.1)

 

-          Remove the higher gcc reference and create a softlink to /usr/bin gcc

[apdpro@dbmig ~]$ cd /u03/dproora/8.0.6/bin/

[apdpro@dbmig bin]$

[apdpro@dbmig bin]$ mv gcc gcc_3.4.6

[apdpro@dbmig bin]$ ln -s /usr/bin/gcc /u03/dproora/8.0.6/bin/gcc

[apdpro@dbmig bin]$ which gcc
