[gradsusr] Enable netcdf 4.1.1 option in grads configure file

Mon Jun 14 13:00:52 EDT 2010

Jennifer –

Yes, I did. I got libdf.a and libmfhdf.a, so I ran ./configure
–prefix=/opt/grads-2.0.a8/ and it is ok, but after run make command I have
many error of ‘Unsatisfied symbol’,

I send you a file with the complete make output in window and unix formats.

I think that I don’t have some library or need special flag to setup?

Please help me,

Best regards,

--Huber

Huber -- 

hdiff is a utility compiled by the hdf4 library, but not needed for GrADS.
Did you already get libdf.a and libmfhdf.a? If so, then put them in
$SUPPLIBS/lib and all the include files in $SUPPLIBS/include/hdf/ and run
./configure (for GrADS) again.

Jennifer,

Thank you for your help, I haven’t compiled the hdf4 library yet, because I
have found the message ‘Unsatisfied symbol “sqrt” in file hdiff_array.o’, I
had thought that the math library was not specify ‘-lm’. Could you tell me
how can I solve this problem? (The error message is in the end)

Please help me,

Best regards,

Jennifer,

Sorry, I can’t understand the patch for gasdf.c,

Change this code block: 

gaint read_metadata (struct gafile *pfi) {

struct gavar *pvar;

gaint rc,i,ii,j,len,ngatts,natts,ndims,nvars,status,oflg,dummy;

size_t sz,size=0;

#if USEHDF ==1

int32 ndsets,dimsize,sds_id,dim_id,dtype,ndatts;

int32 dim_sizes[H4_MAX_VAR_DIMS],rank;

char sdsname[H4_MAX_NC_NAME+1];

char name[H4_MAX_NC_NAME+1],dimname[H4_MAX_NC_NAME+1];

#endif

To this code block instead: 

gaint read_metadata (struct gafile *pfi) {

struct gavar *pvar;

gaint rc,i,ii,j,len,ngatts,natts,ndims,nvars,status,oflg,dummy;

size_t sz,size=0;

char name[300];

#if USEHDF ==1

int32 ndsets,dimsize,sds_id,dim_id,dtype,ndatts;

int32 dim_sizes[H4_MAX_VAR_DIMS],rank;

char sdsname[H4_MAX_NC_NAME+1];

char dimname[H4_MAX_NC_NAME+1];

#endif

but according with to suggest I going to compile hdf4.

Yes, you can also build wtih hdf4 -- but you must use the --disable-netcdf
option when compiling that library.

Thank you

Best regards

Huber

That is a bug that occurs when you build with netcdf but without hdf4.  Here
is the patch for gasdf.c :

# diff dev/src/gasdf.c grads-2.0.a8/src/gasdf.c

2169d2168

< char name[300];

2174c2173

< char dimname[H4_MAX_NC_NAME+1];

> char name[H4_MAX_NC_NAME+1],dimname[H4_MAX_NC_NAME+1];

Hello Jennifer,

Thanks you for your help, I just enabled the netcdf option but now after
make command, akin the error message:

How can I fix this undeclared ‘name’?

Please help me,

Hello,

I’m trying to build grads with netcdf option enable, after I configured the
grads with this command:

./configure -–prefix=/opt/grads-2.0.a8 --with-sdf
--with-netcdf-include=/home/huber/grads/supplibs/include/netcdf > config.out

You should not need to specify any configure options (other than --prefix)
to get netcdf support. I did not write any code to support the
"--with-netcdf-include" option... 

I had the following message that ludunits library is not found:

Checking in supplibs for libraries to support netcdf-4 ...

checking for udunits.h... (cached) yes

checking for utInit in -ludunits... (cached) no

- netcdf-4 disabled

Then, I tried to build the source ldudunits library with the make command,
and also I had this error:

cc -o udunits -O udunits.o -R/data/hoop/udunits-1.11.7/src/lib
-L/data/hoop/udunits-1.11.7/src/lib -ludunits
-R/data/hoop/udunits-1.11.7/src/port/misc
-L/data/hoop/udunits-1.11.7/src/port/misc -ludport -ly -lm

(Bundled) cc: warning 922: "-O" is unsupported in the bundled compiler,
ignored.

(Bundled) cc: warning 901: unknown option:
`-R/data/hoop/udunits-1.11.7/src/lib': use +help for online documentation.

(Bundled) cc: warning 901: unknown option:
`-R/data/hoop/udunits-1.11.7/src/port/misc': use +help for online
documentation.

ld: Can't find library for -ludunits

Fatal error.

Why the compilation needs the ludunits library, I was thought this library
will be the output?

What you're trying to build here is a utility called 'udunits' -- that is
something that is built along with the library, but it is not necessary for
GrADS. 

Look for a file called libudunits.a  -- that is what GrADS needs -- and put
it in your $SUPPLIBS/lib location.

Please help me
