I'm currently working on an open source PHP game, which incorporates a loose framework (very loose - no comparing me to Cake...
There is however log4php (a port of log4j). Became interested after reading about it in phpArchitect, and after reading the source (its a little convoluted but very adaptable). The problem of course is that the project is Apache sponsored, and under the Apache License 2.0.
My question - can such a library be included in GPL source given the glaring disagreement between FSF and Apache? Apache claim their license is GPL compatible, the FSF claim its not - and neither side appear to have resolved the difference. And who knows what surprises GPL3 will bring (coming to a screen near you next week).
What's an open source developer to do - reinvent wheels? Can anyone suggest a similar logging library perhaps?
