CDO

This file contains any messages produced by compilers while

running configure, to aid debugging if configure makes a mistake.

It was created by cdo configure 2.0.5, which was

generated by GNU Autoconf 2.71. Invocation command line was

$ ./configure --prefix=/gpfs/home/jin/tools/pkgs/cdo-2.0.5 --with-netcdf=/gpfs/software/netcdf/intel/netcdf-c-4.7.4 --with-udunits2=/gpfs/software/udunits-2.2.26 --with-hdf5=/gpfs/software/hdf5/intel/1.10.5
