Darn! Forgot to cc the list.

Can someone explain exactly why absolute addresses are needed here? I'm new to wine, but eager to learn.

Wine Staging includes some patches to fix Steam web browsing, but they are deactivated on Mac because they apparently require special build flags. Does anyone know what this refers to?


The staged patchset adds thunk wrappers for ntdll functions, but to be compatible with Windows, they have to contain absolute addresses. This requires text relocations, which are not allowed by default on OSX. Since this issue was discovered shortly before the last release, disabling the patchset on OSX was easier than the necessary configure.ac changes, but I'm working on a solution. Unless we hit some impossible to solve problems Wine Staging 1.7.54 will make the Steam fix also available on OSX. ;)

I took a look at this problem and the patchset and I think we should be 
able to avoid text relocation in this case. I should have a proof of 
concept patch soon.
