Hi Chad, > Package Version: 3.5.0 > Operating System: Windows XP > Hardware: > Description of problem: I downloaded the prebuilt binaries for WinXP > from > ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/win32/netcdf-3.5.0.win32bin.zip > I believe The Fortran library included in that DLL was compiled with a Compaq Visual Fortran compiler, which uses different conventions than g77 for calling C functions from Fortran. > I added ncdump/ncgen.exe and netcdf.dll to my System32 directory. I > pointed my compiler to the appropriate include and library files. I > used MinGW's g77 to compile and link one of the example Fortran 77 > programs (simple_xy_wr.f) that creates a simple netCDF file. I invoked > the following command and got the following output: > > g77 simple_xy_wr.f -IC:\netCDF\include -LC:\netCDF\lib > > cc6pR35H.o:simple_xy_wr.f:(.text+0xb8): undefined reference to > `nf_create> __' > cc6pR35H.o:simple_xy_wr.f:(.text+0xff): undefined reference to > `nf_def_di> m__' > cc6pR35H.o:simple_xy_wr.f:(.text+0x146): undefined reference to > `nf_def_d> im__' > cc6pR35H.o:simple_xy_wr.f:(.text+0x1a8): undefined reference to > `nf_def_v> ar__' > cc6pR35H.o:simple_xy_wr.f:(.text+0x1d0): undefined reference to > `nf_endde> f__' > cc6pR35H.o:simple_xy_wr.f:(.text+0x209): undefined reference to > `nf_put_v> ar_int__' > cc6pR35H.o:simple_xy_wr.f:(.text+0x231): undefined reference to > `nf_close> __' > cc6pR35H.o:simple_xy_wr.f:(.text+0x2e7): undefined reference to > `nf_strer> ror__' > collect2: ld returned 1 exit status A program compiled with g77 in general can't be linked with a DLL containing code compiled with a different Fortran compiler. You would either have to use the same compiler used to make that DLL or regenerate a new DLL using gcc and g77 (or gfortran). If you decide to recompile from source, you would probably have more luck with a more recent source distribution than 3.5.0, with bug fixes and protability improvements.
