Description
I used to work with geodjango using Django 1.7 on Windows 7, and everything was working well. After having upgraded to django 1.8, loading the gis app causes an error.
Here is the full Traceback:

After some searches, it appears that other people had this problem when using GeoDjango + Django 1.8 + Windows (example: https://gis.stackexchange.com/questions/143110/geodjango-setup-python-gdalallregister-attribute-error/144407#144407). But I could not find any fix for this.
I investigated a bit, and found out that at django.contrib.gis.gdal.libgal, we can see this:
..| 47| # This loads the GDAL/OGR C library 48| lgdal = CDLL(lib_path) 49| 50| # On Windows, the GDAL binaries have some OSR routines exported with 51| # STDCALL, while others are not. Thus, the library will also need to 52| # be loaded up as WinDLL for said OSR functions that require the 53| # different calling convention. 54| if os.name == 'nt': 55| from ctypes import WinDLL 56| lwingdal = WinDLL(lib_path) ..|
So when the os is Windows, the GDAL library is also loaded as a DLL, so we have two GDAL libraries, lgdal and lwingdal.
But if we look at the django.contrib.gis.gdal.prototypes.raster (where the "'GDALAllRegister' not found" error is raised from), we can see that the one used is lgdal:
..| 29| # Raster Driver Routines 30| register_all = void_output(lgdal.GDALAllRegister, []) 31| get_driver = voidptr_output(lgdal.GDALGetDriver, [c_int]) 32| get_driver_by_name = voidptr_output(lgdal.GDALGetDriverByName, [c_char_p], errcheck=False) 33| get_driver_count = int_output(lgdal.GDALGetDriverCount, []) 34| get_driver_description = const_string_output(lgdal.GDALGetDescription, [c_void_p]) ..|
It seems like on Windows, lwingdal should be used, so I added this after the imports:
..| 15| # Fix for windows users 16| if os.name == 'nt': 17| from django.contrib.gis.gdal.libgdal import lwingdal 18| lgdal = lwingdal ..|
And it solved the problem for me! Maybe there is something more, it seems a bit too easy, but I still had no issue with it, and I now can use the GIS with Django 1.8 on Windows, which was impossible before this.
Hope I helped...
Regards,
Dimitri.

After applying that patch, I have the following test failures on my Windows system. Some of them may have preceded the work on rasters, but the raster failures are a bit troubling as far as confirming this patch is correct. Do you have any expertise to help resolve them? GDAL version is 1.11.2.

I managed to fix some of the failures. The remaining failures are below (not sure if they are Django problems that need to be fixed or a problem with my test machine setup).

Hello,
Thank you for having fixed the issue! About the raster test failures, I have not the expertise to help with this since I'm mainly working with vectors, and not so much with rasters...
PS: Sorry for not having been more reactive, I did not received any notification about your comments.
Created a PR based on the proposed fix. Going to try to see if I can get the GIS tests running on Windows to confirm the fix.
