APAR status

• Closed as program error.

Error description

• -WE is supposed to pass CreateExportList parameters from the xlC
  invocation to the script.
  
  But it apprears that it's not. This could be seen by adding -V
  to the compile.
  
  Invoking CreateExportList script directly, one can see the
  script itself is working fine.
  
  
  xlc/xlC is not recognizing the -WE, options.
  
  
  ===== TESTCASE:
  Use -V to show the problem.
  
  To demonstrate that CreateExportList is working fine, one could
  try the -WE,-w option with a .C file that has an inline function
  so that the symbol will be weak.
  
  $cat t.C
  #include <stdio.h>
  int foo(int);
  int main( )
  {
  int x=1;
  printf("foo=%d\n", foo(x));
  return 0;
  }
  
  inline int foo(int x1)
  {
  return 5*x1;
  }
  
  
  $xlC t.C -c -o t.o
  
  $xlC -qmkshrobj -WE,-w -qexpfile=exp t.o
  $cat exp
  foo__Fi
  main
  
  Symbol foo_Fi is weak. It shall not appear in the exp file since
  -WE,-w is present.
  
  Invoke createExportList directly to pass the -w option, foo_Fi
  will be removed from the exp file.
  
  
  $/usr/vac/bin/CreateExportList exp t.o -w
  $cat exp
  main
  

Local fix

• Use createExportList script directly.
  

Problem summary

• PROBLEM DESCRIPTION: Options specified via -WE are not passed
  to CreateExportList
  
  USERS AFFECTED: Any user who tries to pass option to
  CreateExportList
  

Problem conclusion

• Problem is fixed.
