Subscribe

APAR status

  • Closed as program error.

Error description

  • When compiling with -qipa=level=0:inline=noauto -qipa=relink,
    the resulting link fails with unresolved symbol error.
    
    The error goes away if we remove the
    "-qipa=level=0:inline=noauto -qipa=relink" from the compile
    step.
    

Local fix

Problem summary

  • USERS AFFECTED:
    Users using exception handling, that have mixed IPA and non-IPA
    objects in an archive may run into unresolved symbols during
    link time.
    
    PROBLEM DESCRIPTION:
    Unresolved symbol errors are emitted by the AIX linker when
    linking IPA compiled and non-IPA compiled objects with IPA
    enabled.
    

Problem conclusion

  • The compiler has been fixed to detect and handle the above case
    properly by choosing IPA definitions over definitions from
    shared objects.
    

Temporary fix
