CAM build failed(problem in building ESMF library)

[cam_iitd10@gmail_com]

I am fairly new to CAM.
I am installing CAM3.0 on Red Hat Linux which is supported
by operating system CENTOS.
while installing I am facing certain problems. After the successful
execution of

% ./cam1/models/atm/cam/bld/configure

problem lies in executing gmake in the building of ESMF library.
after the execution of gmake i got the following output.

[2009ast3222@ajaymeru cam]$ gmake
cd /shome/2009ast3222/cam/cam1/models/utils/esmf;
echo "Build the ESMF library.";
echo "ESMF is NOT supported by the CCSM project, but by the
ESMF core team in NCAR/SCD";
echo "See http://www.esmf.ucar.edu";
gmake -j 1 BOPT=O
ESMF_BUILD=/shome/2009ast3222/cam/esmf
ESMF_DIR=/shome/2009ast3222/cam/cam1/models/utils/esmf
ESMF_ARCH=;
Build the ESMF library.

gmake[1]: Entering directory

makefile:15:
/shome/2009ast3222/cam/cam1/models/utils/esmf/build//base: No such
file or directory
gmake[1]: *** No rule to make target
`/shome/2009ast3222/cam/cam1/models/utils/esmf/build//base'. Stop.
gmake[1]: Leaving directory

gmake: *** [/shome/2009ast3222/cam/esmf/lib/libO//libesmf.a] Error 2

so i want to know what changes and where it should be done to build the
ESMF libraries successfully.

Is it possible for you to update to CAM4? The only part of the ESMF library that cam requires is the time manager functionality. In CAM4 we supply a fortran90 implementation of just the time manager functionality which doesn't require any special build rules. It is much more robust than the prototype ESMF library that was supplied with CAM3.
