Hi:
I noticed that whenever I use a math function (such as sqrt, cos, log) in a
forall all statement that further uses of that function caused gfortran to say
that the function has no implicit type. I've shown an example program below:
program test
implicit none
integer :: i
real :: a, c(5) = (/1.0,2.0,3.0,4.0,5.0/), d(5)
a = sqrt(2.0)
d(:) = 0.0
forall (i = 1:5, sqrt(c(i)) < 2.0)
d(i) = i
end forall
end program test
If I try to compile the above program I get the following error:
In file test.f90:8
a = sqrt(2.0)
1
Error: Symbol 'sqrt' at (1) has no IMPLICIT type
If I comment out the line "a = sqrt(2.0)", everything works fine. Also, if I
don't use the sqrt test in the forall statement, everything works fine. If you
substitute other mathematical functions for sqrt (such as log or cos) it fails
to compile in a similar way.
I tried this in the latest experimental build (downloaded from the gfortran
wiki) and had similar problems.
Thank You
