最近，尝试着调试CESM(1.2.2)模式，虽然迄今为止还没有成功运行，但是遇到了很多问题，中间无数次的想放弃，前前后后差不多两个星期，未来如果可以成功运行CESM的话，将会完善这篇攻略，今天写把刚遇到的问题记下来。

问题1:

WARNING: did not find netcdf fortran library
NETCDF built with hdf5 MPIIO support
-- Could NOT find HDF5 (missing:  HDF5_LIBRARIES HDF5_INCLUDE_DIRS)
-- Could NOT find NETCDF (missing:  NETCDF_Fortran_LIBRARY)
CMake Warning at CMakeLists.txt:63 (MESSAGE):
 Warning: Not building with PNetcdf - cannot run all regression tests.

需要修改：

scripts/ccsm_utils/CMake/FindNETCDF.cmake

若用的是mvapich编译器，并且编译模式遇到问题：ld: cannot find -limpi，则需要在cesm1_2_2/scripts/ccsm_utils/Machines/Makefile中将mpi的lmpi改为lmpich

问题：undefined reference to `netcdf_mp_nf90_strerror_'

NETCDF 4.2以上的版本，需要修改cesm1_2_2/scripts/ccsm_utils/Machines/Makefile里

  SLIBS := -L$(LIB_NETCDF) -lnetcdf 为：SLIBS := -L$(LIB_NETCDF) -lnetcdf -lnetcdff

Calling the short-term archiving script st_archive.sh

st_archive.sh: start of short-term archiving
[: 79: FALSE: unexpected operator
[: 143: ifiles_n: unexpected operator
[: 144: ifiles_n: unexpected operator
[: 145: ifiles_y: unexpected operator
……

方法：修改Tools/st_archive.sh文件，将if [ "$1" == "ifiles_y" ] && [ "$DOUT_S_SAVE_INT_REST_FILES" !== "True" ]及 "$DOUT_S_SAVE_INT_REST_FILES" !== "False"改为if [ "$1" = "ifiles_y" ] && [ "$DOUT_S_SAVE_INT_REST_FILES" != "True" ]及 "$DOUT_S_SAVE_INT_REST_FILES" != "False"

SYNOPSIS
    generate_pop_decomp.pl [options]
OPTIONS
    -res <resolution>    (or -r)   Horizontal resolution (gx1v6 etc.). (default gx1v6))
    -nproc <number>      (or -n)   Number of processors to use.    (required)
    -thrds <number>      (or -t)   Number of threads per processor    (default 1)
    -output <type>      (or -o)   Either output: all, maxblocks, bsize-x, bsize-y, or decomptype
             (default: all)
EXAMPLES

  generate_pop_decomp.pl -res gx1v6 -nproc 80 -output maxblocks

  will return a single value -- the optimum max number of blocks to use.

if: Expression Syntax.
ERROR: pop2.buildnml.csh failed

解决方法，vi Buildconf/pop2.buildnml.csh

 set config = `env UTILROOT=$UTILROOT ./generate_pop_decomp.pl -res $OCN_GRID \
                                -nproc $ntasks -thrds $NTHRDS_OCN -output all`

删除换行符，并合并为一行：“\”:set config = `env UTILROOT=$UTILROOT ./generate_pop_decomp.pl -res $OCN_GRID -nproc $ntasks -thrds $NTHRDS_OCN -output all`
