<div dir="ltr">Hi Salme,<div>This particular example uses a feature of the low level mapping library that is not supported at the NCL level, so unless you are writing Fortran or C code that interfaces directly to the low level mapping routines, it is not important to get this example working.</div>
<div>Instead, if you are primarily using NCL, you should try the 'ng4ex' examples, specifically the NCL versions of these examples, which all have the suffix 'n' (e.g. cn01n).</div><div><br></div><div>That said, the undefined references you get above do seem to be the result of a bug in the build environment for the low level mapping code. I cannot run the example either and I get the same errors you do. We will fix it as soon as we can.</div>
