nco +netcdf4 fails to install

[basmac]

I am trying to get nco +netcdf4 built after hdf5-18 and netcdf4 +dap +netcdf4 build OK. The port info says the variant is availabe -

% port info nco nco @4.0.0 (science)
Variants: mpich2, netcdf4, openmpi, udunits2, universal

I have attached the debug of the build.

The macport build for nco fails the same way on clean install of MacPorts and builds, on Mac 10.5 and 10.6 versions.

port -d nco +netcdf4 output

I cannot reproduce the problem. Does config.h have a line below?

#define ENABLE_NETCDF4 1

May I take a look at config.log?

Updated netcdf to 4.1 in r63794. I am not sure if this helps.

[tenomoto (Takeshi Enomoto)]

Sorry for slow response. This is caused by referring the old version in ${prefix}/lib. Try deactivating nco before install. I am asking for a help with libtool in macports-dev mailing list.

[tenomoto (Takeshi Enomoto)]

My guess that replacement of libnco.la by ${prefix}/lib ./.libs/libnco.a is a cause of duplicate name with the old library ${prefix}/lib seems to be wrong.

Since ./.libs/libnco.a is specified in the full path and nothing else like -lnco, the former should be used. Thus it does not seem to be related with libtool.

I still can't reproduce your problem (Leopard on PPC and Snow Leopard on Intel). I don't have the duplicate symbol between netcdf +netcdf4 and nco +netcdf4.

$ nm work/nco-4.0.0/src/nco/.libs/libnco.a | grep _nc_put_vara_ulonglong
                 U _nc_put_vara_ulonglong
$ nm /opt/local/lib/libnetcdf.a | grep _nc_put_vara_ulonglong
00000000000006e0 T _nc_put_vara_ulonglong
nm: no name list
0000000000005ae8 S _nc_put_vara_ulonglong.eh
nm: no name list
nm: no name list

Can I see the result of these commands?

bash-3.2# port installed|grep netcdf

netcdf @4.0.1_7 (active)

It seems that you have netcdf-4 features are not enabled in your netcdf installation. nco +netcdf4 requires netcdf +netcdf4. There is no explicit way to specify variant dependency at the moment but I added a trick to stop building in such a case in the modified Portfile in r64316. I would like you to try the following.

# deactivate netcdf
sudo port -d deactivate netcdf
# update the port tree
sudo port -d sync
# upgrade those outdated
sudo port -du upgrade outdated
# install netcdf and nco
sudo port -d install netcdf +netcdf4
sudo port -d install nco +netcdf4

The reporter contacted that r64440 fixed the problem.
