Hi,
the following (incorrect) code gives a misleading error message
when compiling:
program gfcbug24
implicit none
interface foo
subroutine foo_8 (a, b)
real (kind(1.d0)) :: a, b
end subroutine foo_8
end interface
real (kind(1.d0)) :: c = 1.d0
! gfortran gives a misleading error message for the following line:
call foo (c, 2.0)
end
% gfortran gfcbug24.f90
In file gfcbug24.f90:13
call foo (c, 2.0)
1
Error: Generic subroutine 'foo' at (1) is not an intrinsic subroutine
This is misleading. There simply is no specific subroutine
whose characteristics matches the (ranks and) types used in
the invocation.
E.g., the Intel compiler v8.1 says:
fortcom: Error: gfcbug24.f90, line 13: There is no matching specific subroutine
for this generic subroutine call. [FOO]
call foo (c, 2.0)
-----^
compilation aborted for gfcbug24.f90 (code 1)
Cheers,
