Re: [Opengrads-devel] the build environment

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

Dear All,
I am finally getting around to working on the build environment. I  
need help!!!

I have changed the expected directory structure of $supplibs/include/  
so now GrADS will look for subdirectories for each library. This led  
to me editing configure.in, acinclude.m4, and src/Makefile.am. I am  
using the latest opengrads src (2.0.a2.oga.1) as a guide. My approach  
is to update things slowly, making sure they work before updating the  
next. So, the dynamic-supplib-detection is not in yet. One thing that  
is not working is adding the proper include directory for netcdf.h  
when compiling grads and gradsdap. This is done with a variable  
called nc_include, which is set in configure.in:

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
   nc_include = "-I\$(supp_include_dir)/netcdf"
   AC_SUBST(nc_include)
   GA_SET_LIB_VAR(nc_libs, [netcdf udunits])
   AC_SUBST(nc_libs)
   AC_DEFINE(USESDF, 1, [Enable netcdf])
   echo "+ netcdf enabled"
else
   AC_DEFINE(USESDF, 0, [Enable netcdf])
   echo "- netcdf disabled"
fi

I put the nc_include variable in  src/Makefile.am like this:
   COMPILE_C = $(COMPILE) $(nc_include) -DUSEDAP=0 -DUSEGADODS=0

But after running ./bootstrap and ./configure, nc_include is empty in  
the Makefile.
Here I grep for it in the top level, and the directories below:

 > grep nc_include *
Makefile:nc_include =
Makefile.in:nc_include = @nc_include@
config.log:nc_include=''
config.status:s,@nc_include@,,;t t
configure:ac_subst_vars='SHELL <....snipped...> nc_include  
<...snipped...>
configure:  nc_include = "-I\$(supp_include_dir)/netcdf"
configure:s,@nc_include@,$nc_include,;t t
configure.in:  nc_include = "-I\$(supp_include_dir)/netcdf"
configure.in:  AC_SUBST(nc_include)

 > grep nc_include */*
autom4te.cache/output.0:ac_subst_vars='SHELL <....snipped...>  
nc_include <...snipped...>
autom4te.cache/output.0:  nc_include = "-I\$(supp_include_dir)/netcdf"
autom4te.cache/output.0:s,@nc_include@,$nc_include,;t t
autom4te.cache/traces.0:m4trace:configure.in:358: -1- AC_SUBST 
([nc_include])
src/Makefile:nc_include =
src/Makefile:COMPILE_C = $(COMPILE) $(nc_include) -DUSEDAP=0 - 
DUSEGADODS=0
src/Makefile.am:COMPILE_C = $(COMPILE) $(nc_include) -DUSEDAP=0 - 
DUSEGADODS=0
src/Makefile.in:nc_include = @nc_include@
src/Makefile.in:COMPILE_C = $(COMPILE) $(nc_include) -DUSEDAP=0 - 
DUSEGADODS=0


What am I doing wrong?

Jennifer
