Access violation writing location when using log4cpp

Question

I successfully compiled log4cpp for Visual Studio 2005 (Debug-mode).

And created a test console application. It links and compiled successfully.

But when I start it in debug-mode, it throws an error:

Unhandled exception at 0x772febc3 in Log4CppClient.exe: 0xC0000005:
Access violation writing location 0x00000014.

This is the content of the output window in Visual Studio:

Access Violation means that you are trying to access a memory address that you don't have permission to access.

Here, in your case, you are trying to write to the address 0x00000014, but you do not have permission/priviledges to do so.

Please share your code for more details.

(Maybe you are using a pointer without assigning it an address first?)
