CDO build fails with duplicate symbol error in cdo-expr_yacc.o
Added by Jed Kaplan about 13 years ago
Dear CDO gurus,
I am trying to build CDO 1.4.7 on Mac OS X with netCDF 4.1.2.
The build fails during the link step with the following error:
ld: duplicate symbol _var in /usr/local/lib/libnetcdf.a(libncdap3_la-ceparse.o) and cdo-expr_yacc.o
There appears to be a symbol "_var" that is used in this version of libnetcdf that is also used in CDO. Maybe this symbol could be given a different name in CDO?
Please find attached the configure and build output, and the result of nc-config --all that describes my netCDF installation.
Thanks for your help!
Jed

Dear Jed,
Thanks for this information! We will rename this symbol in the next CDO release.
Best regards,
Uwe

In your build script, you use a lenghty LIBS setting:
'LIBS=-lhdf5 -lhdf5_hl -ldf -lmfhdf -lcurl -lgssapi_krb5 -lssl -lcrypto -ldl -ldes425 -lkrb5 -lk5crypto -lcom_err -lkrb5support -lresolv'
Since 4.1.1 netcdf uses libtool for building just like cdo. That's why
-lnetcdf should be sufficient for linking. libtool does the rest for you with runtime library path settings.For further optimization, you could use the
-fast option of icc (see #602). CXX is not needed except for compiling experimental ruby/python bindings of CDI, which are switched off be default. In case CDO is the only user of netcdf, you should skip the fortran interface of netcdf (use
--enable-c-only)
