Hi Arjen,
Ah, yes, I see the subroutine being passed as an argument - I totally missed
that. So what would you exactly like me to do now? I was wondering whether you
would like a trial version of the NAG Fortran compiler which may make it easier
:-) Let me know if you would like a NAG Fortran trial licence and I can arrange
one for you.
Best regards,
Wadud.

Hi Wadud,
Well, actually it is: look at lines 3441-3487 for instance:
The label fill() is associated with c_plfill (line 3480) and then that label is
passed as an argument to interface_plshade (line 3499). The label
interface_plfill() is used as a direct call at line 1518.
I am positive that this will work, but that is what the tests/examples are
there for. I imagine that the NAG compiler may find one or two issues in that
code as well, so I would like to suggest you to have the examples built too:
cmake ... -DBUILD_TEST=ON
Regards,
Arjen

Hi Arjen,
I wasn't suggesting removing the c_plfill C function - I meant that its
interface should be removed as it is not being called. The NAG compiler is
complaining about the multiple binding labels "c_plfill". This may seem valid,
but if the fill() subroutine is not being called at all, I don't see the need
to declare interfaces to it.
If I change the binding label of interface_plfill to "fill", the NAG compiler
does accept it, but will that call the C fill() function?
Regards,
Wadud.

Hi Wadud,
Well, the first answer (by Wolfgang Kilian -
https://groups.google.com/forum/?hl=nl#!topic/comp.lang.fortran/-NYIZX-XZag) to
my post does support NAG's view. Unless there are strongly opposing replies, I
think the best way forward is to apply the workaround.
The fill() problem you mention is of a different order. In its current form it
uses two different labels for the same C routine, but the fill routine is
actually used, so we cannot simply eliminate it. (You have to look carefully
though to see where and how ;)). I can see two ways forward:
- Use the same label consistently, either will do. This is only a small
change in the source code.
- Use one interface block for c_plfill - right now the block is repeated
a number of times, mainly to keep these things as local as possible. (I am not
entirely sure if we can prevent "leakage" of the C names, if we do that. I
think that was the background for this set-up.)
If you change the label interface_plfill to fill (or vice versa, that is more
inline with the rest of the naming scheme), is the code accepted by the NAG
compiler? If so, I will apply that to the repository. I will be busy the next
few days, but I will try to incorporate it and do the testing.
Regards,
Arjen
