[gradsusr] error show EOF processing

[krishnamohan]

hi Li,

Here is the procedure which i am following in linux,. Hope it will help you

if you are using linux 32bit OS

download PC(i386) Linux (32bit) from

http://www.atmos.ucla.edu/~munnich/Grads/EOF/



open teminal then gedit .bashrc (your bash file)

your gradspath (where grads is installed) may be (eg: /home/alice/grads )


export GRADS="/home/your_home/grads"
export GADDIR="/home/your_home/grads/data"
export GASCRP="/home/your_home/grads/lib"
PATH=${PATH}:$GRADS/bin

put the following line

export GAUDFT="/home/your_home/grads/udft.txt"

then it will become

export GRADS="/home/your_home/grads"
export GADDIR="/home/your_home/grads/data"
export GASCRP="/home/your_home/grads/lib"
export GAUDFT="/home/your_home/grads/udft.txt"
PATH=${PATH}:$GRADS/bin

before the last line ( that is PATH=${PATH}:$GRADS/bin)

save and exit bashrc

then copy the eofudf file from the extracted directory to your grads folder.

then create a blank file called udft.txt inside your grads folder. then add
the following lines to it


eofudf 2 6 expr value value value value char
sequential
/your/path/to/eofudf <-- Your path to the eofudf executable
eofudf.in
eofudf.out

here set the /your/path/to/eofudf as
/home/your_home/grads/eofudf (where you have copied eofudf)
then it will become excatly in format (dont change the order)

eofudf 2 6 expr value value value value char
sequential
/home/your_home/grads/eofudf
eofudf.in
eofudf.out

then as root copy the library file libcxa.so.3 to /usr/lib
from treminal from the extracted folder (ie: cp libcxa.s0.3 /usr/lib)

go to /usr/lib and change its permission with chmod (ie chmod 777
libcxa.so.3)(this is important)

now exit from root

either open a new terminal otherwise in current terminal give command:
source /home/your_home/.bashrc

now open grads and open your data. then type command: q udft
if it is properly installed it will give something like



eofudf Args: 2 6 Exec: /home/your_home/grads/eofudf

done...........................

now set you time (eg: set t 1 20)

set your lat and lon

then type eof your_variable


it will display and create some output files as ctl and data files which you
can open with grads.
