Porting linux to vxworks & vxworks to linux Porting
karthik bala guru
Does anyone here have information to help/speed up porting from Linux to
VxWorks and vice versa.
Surely, some should have come across the situation and i would
like to get your tips/links/ideas regarding this.
Thanks & Regards,

Posting once is probably enough...
There is a v2linux package by MontaVista. Googling v2linux currently
turns up, "http://legacy2linux.sourceforge.net/v2linux.html". This is
also useful if you develop/host vxWorks on a *nix machine. Instead of
using the simulator, you can compile a native application using this
compatibility layer.
Not sure so much about going from Linux to vxWorks. There is a lot of
functionality available in the bigger OSs that is not available in
vxWorks. For instance, "fork", "pthreads", "mmap", etc. Genearally,
you can steal routines from Linux (like libraries), but it is
difficult to take an application.
fwiw,
Bill Pringlemeir.

For porting there are 3 approaches which are common in the
industry.
1)Build an abstraction layer above your OS and make your application
sit over this abstraction layer.So your application will be
interacting with the abstraction layer and it will inturn call your OS
layer.The advantage is you can change the OS when ever you feel
like,maintaining the sanity of the application with zero effort
required to port the application.
2)The second way will be to make your application with posix calls
instead of normal OS APIs.Vxworks follows POSIX 1003.1b standard and
if you code linux to this standard you will get portable
application.But,the disadvantage AFAIK with this approach is this does
not guarantee real time performance,though I am not very much sure of
this.
3)Purchase any commercially available porting kit as stated by Bill
and use the kit to port.
Finally if you are looking for tips look into
www.bluedonkey.org-->go into vxworks cookbook site--->check for
porting link.
http://www.bluedonkey.org/cgi-bin/twiki/bin/view/Books/MigratingVxWorksToLinux
This will provide you some tips on porting,though its for moving from
vxworks to linux,I believe you should be able to work out porting from
linux to vxworks in a similar manner.
Hope this helps,

Ideas are nice and fine. :) Thanks to JohnGordon's effort and Subbrayan
for letting me know the link. :) :)
The link bluedonkey.org has good contents section, but the actual
section is found to be empty(that is yet to be developed, only some
part of the sections have been found to be written. Other sections have
to be written ). :(
It would be really very nice and kind of you, if someone could give me
the original link or the 'bluedonkey.org link' in a completed form. :)

- I cannot find anything in this section - this section could be of
great help to anyone - So, i would like to request JohnGordon to do it
for the opensource community - OR, kindly give me the completed good
link regarding the porting.
I did not get JohnGordon's mail ID, else i would have mailed him for
the completed pdf / doc/ link .
:) :) :)

Got his ID,
john_...@yahoo.com is Mr.JohnGordon mail ID.
Anyhow,
could someone give me some good-link to download the VxWorksCookBook
and VxWorksToLinux ??
Thanx and Regards, :)

Glad you already knew the answer. Ker-plunk.

You have the link to all there is at the moment. I am currently swamped
with work for my current day job, so don't have much time to fill in
stuff in either of the two books (or even reply here as often as I used
to). I do have some more raw materials for the Cookbook waiting to be
written, but not so much for the porting guide.
TTFN,
John...
