LI77451: IPA LINKING WITH WRONG LIBRARY EXTENSION

XL C/C++ for Linux Fix Pack 9 (August 2013 Update) for 11.1
XL C/C++ for Linux Fix Pack 8 (June 2013 Update) for 11.1

APAR status

• Closed as program error.

Error description

• Similar to the previous APAR IV14250, when the IPA compiler
  component links with a library, it is linking with libraries
  with file extension *.so before libraries with file extension
  *.a when the -brtllib option is used.  This is an issue when two
  libraries with the same name, but different file extensions
  exist in the same directory.
  
  This can cause incorrect linking behaviour and symbol errors
  when the final ld link is performed.
  

Local fix

• - Rename the libraries so that they do not match
  - Remove the -brtllib option
  

Problem summary

• PROBLEM DESCRIPTION:
  The IPA compiler component links with the incorrect library
  when the -brtllib option is used.
  
  USERS AFFECTED:
  Users of -brtllib
  

Problem conclusion

• The '-brtllib' option is now correctly interpreted, and is
  forwarded to the AIX linker.  The '1586-001 (W) Option
  '-brtllib' is not valid.' warning is no longer output.  Instead
  the following warning is now used:  1586-083 (W) ld option
  -brtllib ignored by IPA
  

Temporary fix
