Error description

  • A test case compiles clean with the original compiler options,
    but gives name lookup error using the variadic templates
    feature with -qlanglvl=variadictemplates:
    
    "test.cc", line 164.25: 1540-0274 (S) The name lookup for
    "copy" did not find a declaration.
    "test.cc", line 164.25: 1540-1226 (I) Declarations for
    non-dependent names are resolved in the template definition.
    "test.cc", line 164.25: 1540-1227 (I) "copy" does not depend on
    a template argument.
    ....
    

Local fix

  • Do not use -qlanglvl=variadictemplates
    

Problem summary

  • PROBLEM DESCRIPTION: Invalid name lookup error found in
    template definition
    
    USERS AFFECTED: The problem may be exposed when using
    -qtmplparse=error or -qlanglvl=variadictemplates allowing the
    compiler to type check non-depenent expressions in a template
    definition.   The compiler was missing the fact that a name was
    dependent and analyzing it in the template definition causing
    the error.
    

Problem conclusion

  • The problem is fixed. Apply recommended service.
    

Temporary fix
