building x264 under cygwin/mingw

I want to build x264 binary for win32 under cygwin. The only problem so far is that i can't achieve having multithread support: when i simply pass './configure --enable-pthread' to bash i get nothing:

Code:

Platform:   X86
System:     MINGW
asm:        yes
avis input: yes
mp4 output: no
pthread:    no
debug:      no
gprof:      no
PIC:        no
shared:     no
visualize:  no

You can run 'make' or 'make fprofiled' now.

I took pthreads-win32 from ftp://sources.redhat.com/pub/pthread...release.tar.gz and compiled it using 'make clean GC' and put obtained .dll into /cygwin/bin and /cygwin/lib (by the way on http://ffmpeg.arrozcru.org/wiki/inde...title=Pthreads it is adviced before compilation to apply a patch "regarding POSIX compatibility" - having applied the patch i couldn't compile it...). And no matter if i put this .dll or not - the result is still pthread: no.

Could anyone say what is the problem and how to compile x264 with pthread support under cygwin?

You must build PThreads with "make GC-inlined" or even "make GC-static" and then put the resulting libpthread(GC2).a file (that is the library which will be linked against x264) into your "lib" directory!
Furthermore the required includes (pthread.h, semaphore.h and sched.h) must be located inside your "include" directory. The DLL isn't needed at all, if you built the static version of pthreads...

(BTW: It seems most people built x264.exe with static pthread library in order to avoid the dependency on an "external" DLL file)
