I have been documenting my progress on porting the WebKit project to Haiku on the Haikuware site, but decided to also post information here. You may want to read my previous blog article about this port and also the information at the WebKit bounty on Haikuware. Please consider donating to a bounty.
Before I started work on this port I asked in the #webkit IRC channel what the mimimum version of GCC that was required to compile WebKit. The general consensus was 4.0. So what does that mean?
