For
IMPORT
the error occures in expr.c's check_init_expr
case EXPR_VARIABLE:
if (e-symtree-n.sym-attr.flavor == FL_PARAMETER)
{
t = simplify_parameter_variable (e, 0);
break;
}
gfc_error (Parameter '%s' at %L has not been declared or is
It should have actually matched FL_PARAMETER, but for some reasons it has not.
For
IMPORT :: dp
it happens in trans-decl.c's gfc_create_module_variable:
/* Only output symbols from this module. */
if (sym-ns != module_namespace)
{
/* I don't think this should ever happen. */
internal_error (module symbol %s in wrong namespace, sym-name);
}
I don't see immediately how to fix this. If someone has a good spontaneous idea
... otherwise I try to understand how it should work.

--- Comment #10 from burnus at gcc dot gnu dot org 2006-11-15 20:50 --- For dp (= kind) I really need to find out where to modify this. Somehow this is not properly recognized as constant expression. (Tested by using no import and commenting the check in variable_decl. This is essentially what happens with import.) * * * Some more tests: If one changes the module to a program or only puts the dp into a module, but the interface into a program, import :: dp works. (import does not.) If the interface is in a module (same or different one than dp), the ICE occurs. Import does not work at all for kind=...; it works, however, for type(mytype), regardless whether it is in a module or not. import :: mytype does not work in a module. -- burnus at gcc dot gnu dot org changed: What|Removed |Added Severity|enhancement |normal http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27546

--- Comment #2 from burnus at gcc dot gnu dot org 2006-11-07 16:36 --- Syntax: IMPORT [[ :: ] import-name-list] May only appear in the interface body, i.e. interface import is wrong, but interface subroutine foo import is ok. (It would be nice if one could give a good error message for the first case - as for the case that one puts it outside an interface block.) Current check is in decl.c:1216. One needs to reject also interface type bar end type bar subroutine import bar if bar does not exists in the host scoping unit. -- burnus at gcc dot gnu dot org changed: What|Removed |Added CC||burnus at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27546
