[netCDF #LDE-989755]: request for assistance: strange runtime messages

Howdy Kamen!

Wow, these are weird messages. I note that they are neither errors nor 
warnings. The loader is telling you where it is finding each function, and not 
just netcdf functions, but also C library functions.

Does this happen without netCDF? Try commenting out all the netcdf code in your 
program, but leave in a call to a math function like floor. Now link with -lm 
and without -lnetcdf. Do you see the same problem?

Did you install netCDF from source on this machine? If so, did this problem 
occur when the test programs were compiled for "make check"?

Thanks,

Ed
