hello. i'm the main author of Ardour and JACK, projects those of you with audio/music leanings may be aware of. i'm in the middle of trying to add "native" windows/x86 VST plugin support to these systems, and i ran into some problems. #winehackers suggested to write this list.
we are using a modified version of the Mono hack that allows use of winelib as a shared library. i got things working very well until i tried to use a VST plugin that appears to call RtlCreateUserThread.
in tracking down why it wouldn't work, i discovered that server_init_thread() is called from the NT DLL for 2 reasons:
1) to initialize the first thread in a winelib-supported program 2) to initialize all later threads
there appear to be some problems caused by this. server_init_thread() makes a rather basic assumption: the thread making the request is the target of the request. this is true for case (1) but not for case(2). in case (2), AFAICT, all (most?) instances of "current" need to be replaced by a struct thread* that points to the newly created (but not yet running) thread that is being initialized.
it wouldn't suprise me if i have misunderstood things here, but i was able to fix the first problem i encountered (a complaint that the new thread was already running) by adding a kludgy hack based on my understanding. the next problem emerges because the new thread doesn't get its reply/wait fd's set up (instead, the operation is done on "current").
comments? thanks.
