More information from fparser ('Is Fortran correct?')

[Mohit Dalvi (mcdalvi)]

Hello,
I am introducing a new kernel routine in lfric_apps and the build is failing during psyclone.mk execution (possibly from fparser2) with 'Is Fortran correct?'
Given that this routine contains ~840 lines it would help if specific information was available regarding the error.

In the past I have been able to debug by running fparser2 offline after loading the lfric module(s), but in this case it only prints out the copyright statement and no other errors.

Is there a way to obtain more verbose output from the PSy/ fparser step?

Yes, fparser2 can be hit and miss :( I think if the error is in the declaration, you often get nothing (or just the initial comment lines), but if it's later, you might get a line number (based on a few not very systematic tests :) ). I am not sure if any of the other psyclone/fparser dev follows this board, can I recommend that you post your problem including the source code at https://github.com/stfc/fparser/issues?

Thanks Joerg, at least that is something to start looking at !

No guarantees, but if you post your source code, I might be able to narrow it down (one obvious solution, try to compile it with different compilers ;) ) - but in anyway, we want this as a ticket in fparser, so we can properly fix it. And I have to admit, till I tested it just now, I wasn't aware that fparser would sometimes not output anything, whenever I had bugs, I would get something I think.
