[netCDF #LAW-256659]: nc-config problem with netcdf-4.1.3-rc1 and static linking

> Hi
> 
> The new build system in 4.1.3-rc1 gives an incorrect nc-config when static 
> linking is combined with an installation prefix that differs from the 
> location of the other libraries (like HDF5).
> 
> I am on Cygwin and am building with static linking for the reasons most 
> recently explained in ticket YSA-381038. My C libraries are in /usr/lib (z, 
> curl) and /usr/local/lib (hdf5). Because I am building with a non-standard 
> Fortran compiler I use an installation prefix that differs from either of 
> these. As suggested in INSTALL, I tell configure where to find hdf5 using 
> CPPFLAGS and LDFLAGS. The full command is:
> 
> 
> CC=gcc FC=g95 CPPFLAGS="-DpgiFortran -I/usr/local/include" 
> FFLAGS=-fno-second-underscore FCFLAGS=-fno-second-underscore 
> LDFLAGS=-L/usr/local/lib ./configure --disable-shared --enable-netcdf-4 
> --enable-dap --with-libcf --prefix=/usr/local/netcdf4-g95
> The nc-config scripts gives libraries as follows:
> 
> 
> $ ./nc-config --libs
> -L/usr/local/netcdf4-g95/lib -lnetcdf -lhdf5_hl -lhdf5 -lm -lz -lcurl
> $ ./nc-config --flibs
> -L/usr/local/netcdf4-g95/lib -lnetcdff -lnetcdf -lhdf5_hl -lhdf5 -lm -lz 
> -lcurl
> But the hdf5 library location is not included in this list, so I have to 
> specify "LDFLAGS=-L/usr/local/lib" every time I link, which I think you'll 
> agree is a bit of a drag. (I edited the nc-config script instead.)

Howdy Mark!

I have fixed this in the codebase, both in the main trunk and the 4.1.3 branch. 
I am regenerating the snapshot release now - perhaps you could grab it and let 
me know if it works for you now.

Thanks,

Ed
