iOS Log4Cocoa

[badmac78]

I've been developing for about a year now with XCode and wanted something more descriptive when debugging. I found that someone had created a Log4j port for Cocoa (Log4Cocoa). Trying to get the framework to work, but I get the following error when compiling. Any ideas?


Using XCode 3.2.3

Build WordsThatFit of project WordsThatFit with configuration Debug

There's no framework search path that includes the directory where your Log4Cocoa framework is found.

Did you add the Log4Cocoa.framework file to your project? That should be all that's needed to find it.

If you are developing for the iPhone be aware you cannot use Frameworks in it. You can use statically linked libraries as they are linked into the executable at compile time. There is no dynamic/run-time linking on the device.

Hi i use log4cocoa in my projects and i like it a lot*
however i agree the documentation is not as good as it could be. Here is a link which should get you going. Its for using it with iphone development, but with one exception (categories) it should work for os x too.

Hope this helps
