HI,
I am trying to compile a Fortran code that has a string concatenation in a compute region.
The code does not compile giving this error:
NVFORTRAN-S-1058-Call to PGI runtime function not supported - pgf90_str_copy_klen
The line it is referring to is:
call ffopen (IO_TEMP2,'ssinflow_p'//iproc_str,'rw',ierr)
The variable `iproc_str’ is a character array that is present on the device.
Is string concatenation not supported in an acceleration region?

No, sorry. There’s no support for strings in general, only basic character arrays.
Though is “ffopen” a routine to open a file? There’s very limited I/O support on GPU (basically just unformatted print statements), so this couldn’t be used either.
Hi,
Will strings be supported in future releases?
Are they supported in the OpenACC Spec?
Yeah - I realized that the ffopen which calls “open” doesn’t work anyways so I am changing that code.
Good to know about the string limitation though.
Will strings be supported in future releases?
I don’t believe we have plans for it, at least not in the near term, since there isn’t a compelling use case.
Are they supported in the OpenACC Spec?
The Spec doesn’t define which language features are required to be supported for a target. That’s implementation dependent.
