Cannot compile simple C++ Netcdf program using linked libraries in non-standard directory

Hi,

I'm trying to compile a simple Netcdf test case, as I do not have root access to my machine I've installed the libraries on my workspace /home/s0091681/netcdf2/include and /home/s0091681/netcdf2/lib (I'm using a university Linux system).  When I try to compile I get errors complaining about 'undefined reference' (see snippet)  after a quick Google, it looks like others have had the same problem and it is to do with the order that libraries are linked.

I've used the following in bash:

g++ -I/home/s0091681/netcdf2/include/  -L/home/s0091681/netcdf2/lib -lnetcdf_c++ -lnetcdf -o test simple_xy_wr.cpp

and tried various permutations of the parameters, in different orders etc.

This really shouldn't be as difficult as I'm finding it.  Am I doing something really stupid?

Many thanks

Niall

You should always provide the librarys at the end. Please refer http://www.network-theory.co.uk/docs/gccintro/gccintro_18.html

Hi I tried your suggestion, but still no luck.

bash-3.2$ g++ -I/home/s0091681/netcdf2/include/ -o test simple_xy_wr.cpp -L/home/s0091681/netcdf2/lib-lnetcdf-lnetcdf_c++

There is no space between the libraries in the command you mentioned

bash-3.2$ g++ -I/home/s0091681/netcdf2/include/ -o test simple_xy_wr.cpp -L/home/s0091681/netcdf2/lib    -lnetcdf   -lnetcdf_c++

Hi,

Sorry just realised.  Tried again without spaces.  Produces significantly more error messages now.  Perhaps I'm missing something else, compiler not up-to-date?

trying adding these also to the library list -lhdf5_hl -lhdf5 -lz

ie
g++ -I/home/s0091681/netcdf2/include/ -o test simple_xy_wr.cpp -L/home/s0091681/netcdf2/lib    -lnetcdf   -lnetcdf_c++   -lhdf5_hl -lhdf5 -lz

sorry could u try this

bash-3.2$ g++ -I/home/s0091681/netcdf2/include/ -o test simple_xy_wr.cpp -L/home/s0091681/netcdf2/lib  -lnetcdf_c++   -lnetcdf

Hi, I've installed the previous netCDF distribution so 3.63 instead of 4.  Got it working now.  I guess 4 had a dependence on something not installed on my machine.

Works with the first command you suggested so I'll accept that as solution.

Thanks very much for the help!
