Re: Problem building netcdf-1.0.0 on Mac OS 10.8 using recent compilers.

Hi.

I'm getting pretty much the same error when I use any of the following compilers that are available to Fink users on OS 10.8 to install the netcdf package:

Apple's clang:
 clang --version
Apple LLVM version 4.2 (clang-425.0.28) (based on LLVM 3.2svn)

Apple's llvm-gcc:
$ llvm-gcc-4.2 --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

FSF gcc 4.7.3 or 4.8.1 (we have earlier gcc's for prior OS versions, but I'd like to be able to put out a package that works on 10.8)

The failure is as follows (slightly re-ordered):

mkoctfile __netcdf__.cc -L/sw/lib -lnetcdf

__netcdf__.cc:112:15: error: ambiguous conversion for C-style cast from
      'octave_int<unsigned long long>' to 'size_t' (aka 'unsigned long')
          start[i] = (size_t)tmp(ndims-i-1);

Any thoughts on a workaround?

Hi,

Does it work if you simply use

start[i] = tmp(ndims-i-1);

instead of

start[i] = (size_t)tmp(ndims-i-1);

at line 112 of __netcdf__.cc.

Cheers,
Alex
