Initial compilation hurdles fixed.  Wine builds and installs but something isn't quite right and all applications crashes when trying to create their respective initial processes.  Unfortunately wine crashes trying to execute an illegal instruction (all zeroes) well after the process has well and truly gone off the rails, so gdb is useless.

Why?

One word: winelib! There are several large open source projects that, for one reason or another, targeted Windows at their genesis. Many of these projects are quite old, well established, and would take many man-centuries of work to rewrite for native Linux systems. Enabling wine on ppc64 gets us a cheap way to allow these projects to run (when built from source) on ppc64 systems via winelib.

Status

Command line
Wine configuration

Initial port complete. winecfg starts and runs on ppc64el systems (64KiB page size tested).

To-Do

  • Add ppc64 (big endian) support

Initial patches

Semi-monolithic (will be split further when closer to merge):
