[netCDF #JFN-500782]: netcdf-c make check failure


It looks like the error is related to a change with how the new compiler is 
representing -Infinity, and Infinity; it looks like it is using -inff, inff, 
-inf, etc.  This suggests that the failure's you're seeing are a result of the 
string comparison in the check, and not the result of an error in the software 
itself.  It is probably safe to ignore.  We will take a look at seeing how we 
might best accommodate this; I have to assume it reflects a change in the C 
spec (it would be weird for Intel to provide a representation that was not part 
of the spec), but I am uncertain without doing some research.

I would suggest you can simply ignore these string comparison-related issues 
for the time being.



> Hello,
> I'm trying to compile netcdf-c (version 4.9.2) using the new Intel Oneapi 
> compiler icx.
> The architecture is AMD EPYC 9654 96-Core Processor.
> It compiles, but fails with make check. It compiles and checks when using gcc 
> or an older Intel icc suggesting it's not the HDF5 version (1.14.3).
> Attached are output logs from configure, make, and make check plus the test 
> suite log file.
> Suggestions?
> Thanks,
