Port an application from QNX to embedded linux

linux ?



I Just attended a talk from SYSGO (www.sysgo.com). They described ways
to port embedded applications developed in VxWorks to embedded linux and
stated that it often is not very difficult and that many of their
customers already went that way. Supposedly the situation with QNX is
similar.

Apparently they did not provide the paper on line.

 "http://www.google.ca/search?as_q=vxworks&as_sitesearch=www.sysgo.com "

MontaVista has some documents, but some are hidden on a password
protected sight.

fwiw,

The attendees were supplied with a file PDF that contained the
presentation used during the (nearly free) speech. I think they would
send it to you on request.

BTW. I would take a look at ELinOS. Same might help you to create you
"Distribution".

Sorry, wrong thread.

Which version of QNX, and which version of "embedded Linux"?  What
does your application do? If you want good answers, ask good
questions.  Otherwise you're asking a bunch of strangers to help you
by guessing what your problem is.

If you are using QNX 6, porting should be easy.  Both use the GNU
compiler tools, both support POSIX, pthreads, etc.  However, you could
be in trouble if your code has strict real-time requirements since
Linux will not match QNX's performance in that regard.

If there are hard realtime requirements be prepared to use RTAI or such
additionally to Linux. I did not try but I was told multiple times that
this mostly is not a big problem.
