vista 32 位上的 geodjango 访问冲突
我在 geodjango 保存条目时遇到了真正的问题。 它会产生“错误：访问冲突读取 0x??????” 该错误并不表明它正在尝试获取对哪个文件或文件夹的读/写访问权限。
经过研究，我发现其他非 django 程序也有这个问题，有些是通过关闭 Vista 的 DEP 控制器来修复的，但我有点害怕走这条路，我什至不完全确定这是否可以解决问题。
任何人有任何想法......？ Vista 的工作简直是一场噩梦。

Am having a real problem with the geodjango saving an entry.
It produces a "Error: Access Violation reading 0x???????"
The error does not indicate which file or folder it's trying to gain read/write access to.
Upon researching i found other non-django programs that also have this issue, some were fixed by turning off Vista's DEP controller, but am a bit scared to go down this route and am not even totally sure if this would fix the issue.
Any one got any ideas....?
Vista is a nightmare to work on.

正确的
万一其他人遇到这个问题..
问题出在以下引用的文档上：
http://code.google.com/p/geodjango-basic-apps /wiki/FOSS4GWorkshop
如果您从二进制安装 GDAL 或安装 PostgreSQL 9.0
不要在 settings.py 中引用 GDAL dll 文件。
始终在 Windows 系统的 PATH 中设置 VARIABLE_DEFINITION。
罪魁祸首是settings.py中的这个：
GEOS_LIBRARY_PATH='c:\geodjango\gdal\bin\geos_c_fw.dll'
Right
In case anyone else ever has the issue..
The problem was following a doc referenced at:
http://code.google.com/p/geodjango-basic-apps/wiki/FOSS4GWorkshop
if you install GDAL from binary or install PostgreSQL 9.0
DO NOT reference the GDAL dll file in your settings.py.
Always go with setting the VARIABLE_DEFINITION in windows system's PATH.
The culprit was this in settings.py:
GEOS_LIBRARY_PATH='c:\geodjango\gdal\bin\geos_c_fw.dll'
你似乎已经回答了你自己的问题。谢谢你的建议。我也有类似的问题。我也有这样一行：
GEOS_LIBRARY_PATH = r'C:\OSGeo4W\bin\geos_c.dll'
（劫持主题一段时间。我知道人们在 Windows 上找到工作的 geos 二进制发行版时遇到问题。经过几次尝试，似乎OSGeo4W 的发行版适用于我。但我在其他人的博客上读到，其他发行版而不是 OSGeo4W 在他们的计算机上运行。）
因此我删除了这一行并将 C:\OSGeo4W\bin\geos_c.dll 添加到系统的 PATH 环境变量中。之后，它工作正常。所以这证实了托斯卡纳的解决方案。希望它可以帮助遇到同样问题的人们。
You seems to have answered your own question. Thanks for the suggestion. I had a similar issue as well. I also had a line like:
GEOS_LIBRARY_PATH = r'C:\OSGeo4W\bin\geos_c.dll'
(Hijack the topic for a while. I know people have problems with finding a working geos binary distribution on windows. After several tries, seems OSGeo4W's distribution works for me. But I read on other people's blogs that some other distribution instead of OSGeo4W's works on their machines.)
So I remove this line and add C:\OSGeo4W\bin\geos_c.dll to system's PATH environment variable. After that, it works fine. So this confirms Tuscan's solution. Hopes it can help people running into the same issue.
