Re: [Opengrads-devel] dynamic supplibs checking

[Jennifer A. <jm...@co...>]

The src and some binaries are out now. ftp://grads.iges.org/grads/2.0/

The supplibs/include directory names I used are like this:
gadap/  gd/  grib2c/  hdf/  libnc-dap/  libpng12/  netcdf/   
readline/  udunits/  zlib/

I have not used your pre-compiled supplibs. I believe the new code  
should work with them, but I'm sure some changes to configure.ac and  
Makefile.am will be required. For my pre-compiled builds, I rebuilt  
the curl library --without-libidn and --without-ssl and then rebuilt  
all the *dap*.a libraries around that. Hopefully they will be more  
portable. The python interface is not included; without any knowledge  
of python, I can't realistically support it.
