Howdy Alex!

Firstly, let's take this to address@hidden.

Can you send to address@hidden your config.log and the
full output of make check?

You might also try --disable-v2 and see if that solves your problem (at
the cost of the v2 API).

Or you could try defining those symbols as ints. I believe they are part
of the netCDF V2 API error handling...

Thanks!

Ed
