CDO

the error is

/home/taolu/WRF/LIBRARIES/grib_api//lib/libgrib_api.so: undefined reference to `memcpy@GLIBC_2.14'

you seem to have a borken installation. glibc is a system lib. Do you use the installation for anything else?

Thank you for your reply very much.

I did not compiled this

 libgrib_api.so file 

I just copied this from my another computer.

All files I got from manually compilation are

bin
big2gribex         grib_compare           grib_distance  grib_histogram    grib_moments    tigge_accumulations
gg_sub_area_check  grib_convert           grib_dump      grib_index_build  grib_packing    tigge_check
grib1to2           grib_copy              grib_error     grib_info         grib_repair     tigge_name
grib2ppm           grib_corruption_check  grib_filter    grib_keys         grib_set        tigge_split

grib_cmp           grib_debug             grib_get_data  grib_ls           parser

include
grib_api.h

lib
libgrib_api.a  libgrib_api.la

By the way, I compiled grib_api by ./configure --prefix=grib_api --disable-shared.
And got the error:

pgf90 -g -o same_int_long same_int_long.o grib_fortran_kinds.o
/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/4.4.6/crtbegin.o: No such file: No such file or directory
make[1]: *** [same_int_long] Error 2

Unless both computers have same kind of hardware and exactly the same operating system, copying libraries does not work. This messes things up and you'll run into strange error.

You should

• use binary packages for your OS

or

• manually compile the complete library

You wrote, that your grib_api configure call was

./configure --prefix=grib_api --disable-shared

this does not work properly, in you configure call for CDO, you used

 ./configure --with-netcdf=/home/taolu/WRF/LIBRARIES/netcdf --with-grib_api=/home/taolu/WRF/LIBRARIES/grib_api/ --prefix=/home/taolu/WRF/LIBRARIES/cdo --disable-shared

both seem to point to different grib_api directories.

Please, take 5min to think about

• if you really need the last development version of CDO
• if you need grib2 support

the trick is, to compile only the feature you need. grib_api is not very user-friendly.

You are right.

I did not find binary package for Linux.
So I have to compile it myself.

I don't need grib2 support now, but it is better to have one.

I also ask the question about compilation of grib_api, because I think the problem relies on grib_api.
If I solved the question, I will be back.

Please, don't. IMO it's not better, it just puts work on you without a benefit for you.

good luck + a nice weekend!
