Hi Pedro, I am still not able to compile any kind of pthreads with cegcc/mingw32ce. I did some smaller modifications to the source of mingw32e and to pthread-w32-2.8.0, and it almost compiles. But at the end I get lots of undefined references. This is strange, since the compiler flag "-DWINCE" should take care of this, for instance by using the errno hack you mentioned. I commented the following lines out on mingw32Ce files: errno.h 12,13,14,109 signal.h 12 process.h 99,102 And on pthread-w32-2.8.0: ptw32_allUser... 44,45,194 I also changed GNUMakefile on line 66 from "-lwsock32" to "-lws2", since that removes one undefined reference. The other libraries from mingw32ce do not seem to solve any undefined references... I compile with: make CROSS=arm-wince-mingw32ce- CC="arm-wince-mingw32ce-g++ -DWINCE" clean GC The output is at the end of this mail. PS1: I did not find any information on someone compiling pthreads with cegcc/mingw32ce. Do you have some more information? I am not a very experienced programmer, so I guess it would be hard for me to port jamvm to native win32 threads... PS2: There are other kinds of Java for WinCe, but they all have different limitations. See http://www.rainer-keuchel.de/wince/kaffe.html http://www2s.biglobe.ne.jp/~dat/java/project/jvm/index_en.html Kind Regards, Leonardo.

I though that there was already a port of pthreads-win32 for WinCE at pthreads-win32 upstream. I've seen the patch for it in the past somewhere, and I remember that it wasn't that clean (defined an int errno as a workaround, for example), but it was reported to work by its author. OTOH, how hard would it be to add native win32 threads support to jamwm? Cheers, Pedro Alves ___________________________________________________________ Der frühe Vogel fängt den Wurm.
