[M3devel] HEADS UP: CM3 builds broken

Tue Feb 12 09:45:24 CET 2008

The only other non-NT386/GNU change by me, from a quick scan of ChangeLog, is:

2008-02-10 23:24  jkrell
  * m3-libs/m3core/src/: runtime/m3makefile, thread/m3makefile,    thread/Common/SchedulerPosix.i3, thread/Common/m3makefile,    thread/POSIX/SchedulerPosix.i3, thread/POSIX/m3makefile,    thread/PTHREAD/SchedulerPosix.i3, thread/PTHREAD/m3makefile,    thread/WIN32/ThreadWin32.m3:

  cheat just a tad and provide SchedulePosix interface on Win32 albeit  not a good implementation currently  this way NT386GNU can build with Win32 threads and cm3 gets as far  as printing an error and exiting, probably something to do with  pesky slashes; a lot better than hanging due to nanosleep failing  and worrying about a lot of non trivial cygwin code..
which looks very ok. I moved SchedulerPosix to common and provided a do-nothing implementation for NT386.
This is so NT386GNU can use native Win32 threads, but Posix in other places like i/o.

(Sometimes I wonder...maybe all that's needed is handling forward and backward slashes the same c:/foo/bar, which I already put in, plus allowing X Windows... (Trestle builds now btw...std packages get at least as far as anim3d. Running stuff is known to have problems..the slash issues were just because I had backslashes (and colons) in paths in environment variables... the current problem is that cm3 always seems to think files are out of date and that all builds fail, but it does actually run cm3cg over everything and seems to work...surely an easy issue to deal with...oh I think m3bundle crashes, the only other thing I've run besides cm3...like..for example, keeping time in seconds since 1970 in a 32bit signed integer seems more like a bug than a feature....maybe I'll start another thread here....even the Win32 Modula-3 interfaces I think use that poor representation, just that they go to the effort of converting from a better format....))

Anyway I'll at least test on birch later and maybe install FreeBSD in a virtual machine.....

drat...I'd like to punt just a few hours here and will get to it then.Sorry.I hardly changed anything "live" other than what Tony put back.Yes I need to test more/at-all on Linux/x86 and/or FreeBSD/x86.. Great to have the tinderbox though, catch stuff "early" (yeah yeah, not as early as you'd like).  - Jay
