Unable to attach technology library?

emax

I try to use Cadence gpdk045 but unable to attach the technology library to a newly created library with error:

The binary file 'tech.db' was not found in library 'gpdk045'

However the file is there in gpdk045 directory. I have installed the kit and created the cds.lib according to the instructions in reference manual. These are the steps I followed:

1) In .bashrc set the environment variables

export CDS_Netlisting_Mode=Analog

export CDSHOME=/home/eda/ic610

but I also have another variable:  export CDS_ROOT=/home/eda/ic610 and hope it does not create problem.

2) In the work directory I created a cds.lib file with following entry

INCLUDE /home/user/edasrc/cadence_pdk045/gpdk045_v_3_5/cds.lib

3) and finally created a link in the work directory

ln -s /home/user/edasrc/cadence_pdk045/gpdk045_v_3_5/models

Where is the problem and why I am unable to attach the technology library? In CIW it says Loaded gpdk045/libInit.il successfully!
