I think the build instructions need to be updated. Trying to build on my own and I keep running into problems where the linker is telling me the libraries have no i386 capability. Every attempt I try to install them, results in the same problem. When I run "brew options xxxx" where xxxx is any of the libraries necessary, the --universal option does not appear for any of them. What this is telling me is that home-brew is no longer supporting 32 bit install on mac os x. If you are using a system that already has them installed, then this may be how you are still able to build, but for anybody who doesn't have them??? As a suggestion, the build that you are providing is built against frameworks, but the frameworks you provide doesn't have the headers. If you provide versions of the frameworks that you are using to build (as they have to contain the headers) could be a possibility. Also, the build that you have up on "http://raine.1emulation.com/download/macos.html" is giving a runtime error. The log gives: "Dyld Error Message: Library not loaded: @executable_path/../SDL.framework/Versions/A/SDL Referenced from: /Volumes/VOLUME/*/Raine.app/Contents/MacOS/Raine Reason: Incompatible library version: Raine requires version 12.0.0 or later, but SDL provides version 1.0.0" Somehow the SDL version that it is looking for is incorrect. I have installed the frameworks that you provide into the location you state to put them. Thanks Much
