PI41717: THE NAME LOOKUP FOR "_VACPP_HASH_FUNCTION_CHECK" DID NOT FIND A DECLARATION ERROR MESSAGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The users who include xhashtbl and specify -qlanglvl=extended0x
  may encounter error:
  
  "/usr/include/xhashtbl", line 514.50: CCN5274 (S) The name
  lookup for "_VACPP_HASH_FUNCTION_CHECK" did not find a
  declaration.
  "/usr/include/xhashtbl", line 514.50: CCN6226 (I) Declarations
  for non-dependent names are resolved in the template definition.
  "/usr/include/xhashtbl", line 514.50: CCN6227 (I)
  "_VACPP_HASH_FUNCTION_CHECK" does not depend on a template
  argument.
  
  The reason for this error is that the body of debugging
  function _HashFunctionCheck() uses macro
  _VACPP_HASH_FUNCTION_CHECK in a statement and is only called
  when the macro is defined.  However, this function is not
  guarded by #ifdef _VACPP_HASH_FUNCTION_CHECK.  As a result the
  compiler issues the error message:
  
  "_VACPP_HASH_FUNCTION_CHECK" did not find a declaration"
  

Local fix

• Modify xhashtbl to guard _HashFunctionCheck() with #ifdef
  _VACPP_HASH_FUNCTION_CHECK.
