I am writing a Fortran code with openACC directives and compiling it with nvfortran.
I need to check if a value is NaN, and therefore I used ieee_is_nan function from ieee_arithmetic module.
When I compile, though, I get the following error:
NVFORTRAN-S-0155-Could not resolve generic procedure ieee_is_nan
The result of nvfortran --version is
nvfortran 22.11-0 64-bit target on x86-64 Linux -tp haswell
ieee_aritthmetic.mod is currently on my computer (Ubuntu 22.04), and I set its folder to export PATH in .bashrc file.
Can someone please help me?
