I got some emails about the errors when some users compile and run RegCM4.2 with CLM options after they fixed the bugs according my previous poster.

I can not reply all of you one by one.  So I write this poster to list all the steps:

Step1: fix all the four bugs listed in my previous poster (you can google "Bugs fixed in RegCM4.2 with CLM option")

Step2: define the following environment variable according to the compiler on your system before running configure command

setenv CC gcc

setenv FC pgf90

setenv F77 pgf90

setenv CPPFLAGS '-I/usr/pgi/linux86-64/11.10/mpi2/mpich/include'

setenv  NETCDF            /usr/local/netcdf_pgi

setenv MPI /usr/pgi/linux86-64/11.10/mpi2/mpich

set path = ($MPI/bin $path)

setenv LD_LIBRARY_PATH $NETCDF/lib

setenv LD_LIBRARY_PATH $MPI/lib:$LD_LIBRARY_PATH

Step3: Patch configure file use the attached patch file

The purpose of the configure file is to fix the problem that the configure command can not get the CPPFLAGS value even we define it as environment variable.

Secondly to fix the problem that rcmlib is not included in the path of library to compile CLM.

If you are not clear what I say, I am sorry for this. You can just use the patch file.

Step4: configure and compile

./configure --with-netcdf=/usr/local/netcdf_pgi --enable-clm

make all

make install

Step5: run

mpirun -np 10 ./Bin/regcmMPI_clm regcm.in > & std.out &
