can we create executables for beaglebone black micrcontroller which is a linux based platform having arm processor using labview?If yes,How?
Yes, it is possible using LINX add on for Labview.
Here is how.
As already mentioned, it took 5 seconds to find the link searching Labview+Beaglebone with Duckduckgo.

We develop a server-side solution and to ease its deployment we would like to provide our cutomers with two options:
1. Docker image
2. VM image in OVA format
The images should be automatically created by our build machine.
As of today, we use packer for this purpose. First we create docker image and then update that image in preconfigured virtual machine image (using 'virtualbox-ovf' builder). This works pretty well, but there are some problems with this solution.
First, our vm includes docker framework and two OSes (host's and docker's), so our VM image is ~twice bigger than docker. Second, to base our solution on another linux distro, we should manually configure new VM machine.
We are looking for 'Dockerfile'-style solution to create and configure VM automatically and then export it in OVA format. 'virtualbox-iso' builder is the obvious way to do this, but the building process will be much longer.
If you are willing to use Debian as your base OS then you could look at TurnKey Linux's TKLDev. It's probably a bit of a learning curve initially but it's a pretty cool thing IMO (although I'm very biased - see below disclaimer). TKLDev will build you a TurnKey (Debian based) ISO with your software installed on top. Then using Buildtasks you can convert the ISO to OVA, VMDK, LXC, Docker, OpenStack, etc...
Unfortunately Buildtasks is not very well documented but significant chunks of it are in bash so if you are handy with a Linux commandline you could work it out. Otherwise ask on the TurnKey forums.
The initial development (from Packer to TKLDev) may take a little while, but once the heavy lifting is done the creation of an ISO (in a guest VM on a moderm multicore CPU PC) takes about 10-15 mins and the OVA probably another ~5; Docker another ~5.
If you wanted to make it build automatically then you could use a hook to trigger a fresh TKLDev build (including the buildtasks image creation) everytime a commit was made to a repo. I know that git supports this but I assume that other version control systems allow something similar.
Also if the appliance that you are making is open source then perhaps it could be added to the TurnKey Linux library?
Disclaimer: I work with TurnKey Linux. :)
FWIW this is essentially the process we use to create our library of appliances in most virtualisation formats known to human kind!
I wonder by any chance is there a way to install vxworks on vdx86d(vdx6354)? I searched a lot on the net and did not find NO to this question, but no manual or help could be find by me. anybody did this before and know how to do it?
VxWorks certainly runs on PC architecture x86 targets; there is probably already a suitable 80486 BSP that will suit this board. You can search for a suitable BSP here. There is only one BSP explicitly listed for 486 targetted at VxWorks 5.4/Tornado 2.0 - so it is as antique as 486 architecture itself. VxWorks 6.9 however has a single unified BSP for x86 which will no doubt work with your board.
VxWorks is not "installed" as such in the same way as a GPOS such as Linux or Windows; rather you link your application with the VxWorks libraries to create an application image that runs directly on boot. How the bootstrap process works varies between architectures and hardware implementation, but as a generic PC architecture board, booting a VxWorks application on your board will be the same as any other PC target. As such what you need to look for are directions on booting VxWorks on PC architecture rather then being specific about your actual board.
On PC architecture you can boot from mass-storage, or from a network server. Booting via a network connection is the normal method during debug/development. A great deal of the information available is for older versions of VxWorks. However it seems that it is possible to boot VxWorks via a VxWorks specific bootstrap, or from a generic PC bootloader such a s U-Boot.
Ultimately Wind River Support is probably a good starting point.
As i know java programs are able to run on any Operating System.
and there are JVM's for any kind of machines.
I need a JVM that runs on my PC stand alone, and not on my OS (windows or any thing else).
I mean a JVM that acts like a boot, instead of the OS boot
i searched for all versions of JVM on "www.java.com/en/download/manual.jsp", but i did not get the suitable JVM.
the following link helped me a little but that was not enough
http://java-virtual-machine.net/other.html#jvm
my PC CPU is AMD Athlon(tm) 64X2 Dual Core Processor 5200 + 2.69 GHz
any body can help me to find the suitable jvm version ?!
Sure, have a look at JRockit Virtual Edition. As I understand it it's basically a micro kernel especially tailored for the JRockit VM.
From this page:
Java without the OS: JRockit Virtual Edition (VE)
Am I the only one that's never heard of this before? The Oracle JRockit team is looking at eliminating the OS from the stack required to run Java. This product will be called JRockit VE (not out yet)
JavaOS
Good lucking getting hold of it, though, it's nothing more than a historical curiosity.
There are two JVMs that I am aware of, which have this property:
The Fiji WM: http://www.fiji-systems.com/index.html
According to http://rtjava.blogspot.com/2009/11/new-real-time-vm-was-born-fiji-vm.html it also runs on bare metal.
The next possibility is JNode: an open source operating system where most parts are written in Java (the rest in assembly): http://www.jnode.org/
JNode is still beta, though.
No.
There was an idea of making a machine that could run a JVM as an actual machine (non virtualized), similiar to LISP machines, but that idea never took off...
You need a host OS to run a JVM.
Googling "java real machine" might give you some interesting articles.
I've found two: one from 2004, talking about how such a machine could be built and another one, talking about how JVM runs as a real machine on hardware such as mobile devices.
Still, no dice with a plain PC.
I've read of some WMI solutions which are able to read the temperature of the CPU. I've tried this and it doesn't appear to work for Windows XP Embedded running on an Intel Atom based board.
Is there a library or some other solution out there which would work?
Looks like Core Temp could be a viable solution.
I'm doing a little app that I want to distribute in different platforms, at least the 3 major ones.
Is it possible to use only Windows has the host OS to compile the binaries for Linux, Mac OS X and other supported platforms without resorting to virtual machines?
Or should I ask around in some community to help me compile on, well OS X, actually, since I can virtualize a Linux machine quite easy?
It is possible to compile from one plateform to another, it is called cross-compilation. You will find extensive informations at http://www.stack.nl/~marcov/buildfaq.pdf
The buildfaq above contains sample cross-compilation :
from Windows to Linux,
from FreeBSD to AMD64 Linux
The FPC download page contains :
the i386-win32 to x86_64-win64 cross-compiler
the i386-win32 to arm-wince cross-compiler
The FPC mailing lists are at http://www.freepascal.org/maillist.var
You will find more informations about FPC at http://www.freepascal.org/moreinfo.var

There are some limitations. You can't target x86 from powerpc, because powerpc misses an "extended" type. But in generally it works.
I have generated a complete Lazarus for OS X on Windows.
I would virtualize Linux, as even if you can cross-compile, it means you're not testing the binaries on their native platforms. OS X is a trickier problem.
It is not possible to compile from one platform to another. We have a Mac and use FPC quite often. If you need some help with compiling on a mac, drop me a message.
