Bug #: 50252 Summary: Error message on "call x%y" (x not declared) can be more informative Classification: Unclassified Product: gcc Version: 4.6.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: arjen.markus...@gmail.com If you forget to declare a variable with type-bound procedures, say x, and call one of the intended procedures anyway, the message is simply that there was a syntax error. The program: program test123 call bb%print end program test123 results in the following error message: xx.f90:3.11: call x%print 1 Error: Syntax error in CALL statement at (1) This message could be made clearer by pointing out that a variable may not be declared - if the statement contains a %: Error: Syntax error in CALL statement at (1). Possibly a variable has not been declared.
