I think that the realistic options you have are : 1. Either you have an AIX enthusiast, a knowledgeable guy who regularly supplies team with AIX related patches (that do not break any other platforms;)). Or 2. You provide a machine for the Buildbot, and sponsor the project (the popularity of AIX is IMO too low, to support it for free). It is my personal opinion, not an official position. > Right now, i can successfully build stock MySQL 5.1.70 with some minor > patches and stock MySQL 5.5.32 with some minor patches and the option > "DWITHOUT_PERFSCHEMA_STORAGE_ENGINE=ON".

Can someone please > help me out here? To me , it looks like a sound alternative for AIX environment would be using IO completion ports, the AIX port of Windows API's. Native_event would be OVERLAPPED * Io_port_create, io_port_associate_fd map to CreateIoCompletionPort () io_poll_start_read is ReadFile(), with OVERLAPPED*, 0 bytes length read io_poll_wait is GetQueuedCompletionStatus() io_port_disassociate() cannot be implemented, but it is only used in rare case where thread_pool_size is being changed at runtime. If you do not want to mess with it (you said your C-fu is weak), I attached a patch with dummy implementation of threadpool required methods, it should just make this thing compile, threadpool won't be usable. I did not test it. Wlad PS. Performance schema unit tests should either be disabled or link with sql library (TARGET_LINK_LIBRARIES sql), I gather this from the error output you sent.
