multithread programming

multithread programming

[Alex]

i wanted to learn how to code multithread programms
so i read a tutorial at
http://www.mit.edu:8001/people/proven/pthreads_man.html
and i looked for #include <pthread.h> and i didn't find it in cygwin B19

how can i make POSIX compliant multithread programms with cygwin ?

unfortunatly Cygwin b19 (and b20) are _not_ multithread safe. Therefore the
posix thread pthread package from MIT won't work.

That's at least what core developers have told me on that issue.

Does it mean that it is impossible to port multithreaded application from Unix
to Win32    ???

Actually, recent source snapshots have had a threadsafe option which has
to be manually configured.  This also includes limited pthread support.

of course it _is_ possible if you consider to write pthread wrappers that take out
the multithreading ability of the application.

As you may know, Win9x shouldn't be considererd thread-safe at all, therefore how
could Cygwin fix that if it is a sub-system of the os. I just wanted to say, that
you can't compare Linux or Solaris (or what real UNIX ever) to Cygwin for
multithreading abilities.

I tried to port the MySQL database engine which uses the MIT's pthreads. And I got
stuck into deep trouble with the need of that pthread functions.

Maybe an upcoming release of Cygwin will be supporting the pthread packages in
some way.

All I've ever had to do was copy over the .class files. ;-)

Unfortunately, I'm stuck with MSVC-- for JNI DLLs until the cyg-libs are
threadsafe.

that sound great. So when can I expect to be able to port the MySQL database
engine using MIT's pthread package on Cygwin? Will be Cygwin b21 threadsafe and
pthread supporting?

What do I have to do, to get the pthread support active within the latest source
snapshot? Compile the whole cygwin1.dll? Which options do I have to configure
manually for this?

Yes, you'll need to compile cygwin1.dll.  Try running configure --help .
The options should be self-explanatory.

FYI, the pthread support is limited and the multithread support is still
considered experimental.

Does it mean that it is impossible to port multithreaded application from Unix
to Win32    ???

Slow down a little.  There is currently work at Cygnus to port the
pthread package to cygwin.  I'd check on the progress there first.
