Re: [Opengrads-devel] the build environment

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

I have got it to work by creating a new macro in acinclude.m4:

dnl GA_SET_INCLUDE_VAR : Puts necessary options to compile with  
include directories given
dnl                  into a shell variable.
dnl   args:	   : shell-variable-name, list-of-directories
AC_DEFUN([GA_SET_INCLUDE_VAR],
[
   ga_include_prefix='-I$(supp_include_dir)/'

   for ga_include_name in $2 ; do
       $1="$$1 ${ga_include_prefix}${ga_include_name}"
   done
])


Now configure.ac has this:

use_nc=no
if test "$with_nc" != "no" ; then
   echo "Checking netcdf support..."
   GA_CHECK_NC([use_nc=yes], {})
fi
if test $use_nc = "yes" ; then
   GA_SET_INCLUDE_VAR(nc_include, [netcdf])
   AC_SUBST(nc_include)
   if test $use_hdf = "yes" ; then
     GA_SET_LIB_VAR(nc_libs, [netcdf])
   else
     GA_SET_LIB_VAR(nc_libs, [netcdf udunits])
   fi
   AC_SUBST(nc_libs)
   AC_DEFINE(USESDF, 1, [Enable netcdf])
   echo "+ netcdf enabled"
else
   AC_DEFINE(USESDF, 0, [Enable netcdf])
   echo "- netcdf disabled"
fi
echo

And my Makefile has this:
nc_include =  -I$(supp_include_dir)/netcdf
