Revision 1284 Breaks NetCDF4 Usage with Python 2.7.5 & NetCDF4.2.1.1 on OSX 10.8.5

[Patrick Marsh]

I updated to the latest version of netCDF4-python and it fails on import with the following:

ImportError: dlopen(/Users/pmarshwx/.local/lib/python/site-packages/netCDF4.so, 2): Symbol not found: _nc_rename_grp

  Referenced from: /Users/pmarshwx/.local/lib/python/site-packages/netCDF4.so

  Expected in: flat namespace

I noticed in the install log that I get the following

NETCDF4_DIR environment variable not set, checking standard locations..

checking /Users/pmarshwx ...

checking /usr/local ...

netCDF4 found in /usr/local

using netcdf library version 4.2.1.1

using Cython to compile netCDF4.pyx...

netcdf lib does not have group rename capability

I will point out that I built netCDF4 with Homebrew.

Revision 1283 works just fine.

Hi, Jeff,

This is the case. I *do* have this file. And it *is* set to 0.

Patrick: You should have a file constants.pyx in the same directory as setup.py. It should have

DEF HAS_RENAME_GRP = 0

in it, which means the compiled module should not reference the nc_rename_grp function.  Can you check that this is the case?

I went ahead and did and "svn update" to revision 1286 and it worked. (For completeness, revisions 1284 and 1285 still fail.)

Patrick: Somehow the version you installed used a value of 1 during compilation. I don't know how this could have happened.  There certainly wasn't anything in revision 1284 that would have caused this.  Could you svn update, and rebuild?
