Problem is an unresolved symbol during link.<BR>> <BR>> As soon as I can get the build problem resolved, I'll try out your test program.<BR>> <BR>> Regards,<BR>> Randy Coleburn<BR>> <BR>> -----Original Message-----<BR>> From: Mika Nystrom [mailto:mika@async.caltech.edu] <BR>> Sent: Wednesday, February 09, 2011 5:01 PM<BR>> To: m3devel@elegosoft.com<BR>> Subject: [M3devel] threading on Windows?<BR>> <BR>> Hi m3devel,<BR>> <BR>> I'm just curious if anyone out there who's running CM3 on Windows has had<BR>> a chance to try my thread testing program yet. Current status on Unix<BR>> (Linux, FreeBSD) appears to be that there are problems in pthreads (but<BR>> I think only under heavy load) and that user threading works perfectly.<BR>> So I now wonder how things are on the third threading platform (Windows).<BR>> The thread testing program is at m3-libs/m3core/tests/thread .<BR>> <BR>> (Note however that there is a memory leak in TRY-EXCEPT in the current<BR>> head so don't try to update everything to the CVS head. The previous<BR>> release should be OK.)<BR>> <BR>> Also has anyone else noticed that debugging information has recently<BR>> broken? m3gdb is very unhappy on all platforms for me...<BR>> <BR>> Mika</SPAN></P></DIV> </body>
