Re: Compiling NC 4.0

John,

A Panoply user with data on the polar stereographic grid
is having troubled because the projection handler in NC
4.0 is throwing an exception parsing the grid mapping
attributes.
you can send me the file and ill check it, but im not sure i have a 4.0 development environment still (I can check tommorrow) 
The dataset tags look fine to me, so I thought I would try
to add a couple lines of output diagnostics to see if I
could get a better grip on why the exception is being thrown,
but that means compiling NC 4.0 from scratch. Unfortunately,
I'm running into a brick wall trying to do so. The ant
compile process is throwing a memory heap error, as shown
below.

Any suggestions in how to deal with this? I'm using OS X
and the machine has 5 GB of memory.
im guessing that you need to add something like "-Xmx512m" option to your javac invocation. basically the symbol table has gotten too large for the default heap size. 
(And yes, I know NJ 4.0 is getting long in the tooth, but I'm
stuck using it a little longer until more of my Mac-based
user base have upgraded their hardware. I'm thinking I will
finally jump up to NJ 4.1 this summer.) would be good

that would be good

Thanks,
rbs
