Build a small linux system with busybox

Hello,
i'm looking for information how to build a small linux system based on glibc and busybox.
I know http://www.linuxfromscratch.org/, but it is quite complex... I want to build a much smaller system.
Has anybody some information about it or knows a good website?
I know there are serveral "build systems", for example buildroot (http://buildroot.uclibc.org/), but i really want to build it "from scratch"
johannes

I have looked at the following a while back. I wanted to try to build a very small system too. I never got so far though, as I didn't have the time for it.
http://tldp.org/HOWTO/From-PowerUp-To-B … HOWTO.html
http://users.cecs.anu.edu.au/~okeefe/p2 … ldMin.html
What I never really could find a precise answer to was how much is really necessary for a system to "startup".
Would it really be enough with a bootloader, kernel and /sbin/init?
(I know there would be just about no functionality in that, but theoretically?)

May LV for Linux run in embeded linux system with ARM9 ?

Hello All,
May LV for Linux run in embeded linux system with ARM9 ?
Tks and best regards!
Bright

No, it will only run on Intel compatible processors.
You'll need LV Microprocessor SDK for that (AKA LVEmbedded). But you'll lose
the MMI. And you need to build toolchains yourself (although there is a
cygwin example shipped, and converting it to any gcc toolchain is not that
difficult).
There is a special LV MSDK for ARM processors, but not for all of them.

Wiebe.

Backing up your Linux systems with the command line

While there are many GUI-based backup and storage tools for Linux users, there are also a few command line-based tools. "Rsync" is one of these tools and, according to Linux.com, it stands for remote sync. With afull tutorial on how to use rsync, Linux.com walks you through how "one of the most used'tools' in the UNIX world [works]."
Even though it's a simple tool, rsync has quite a few capabilities. You can use rsync "to sync files on two directories on the same PC, on two different systems on the same network, [and] .... on machines thousands of miles apart, over the Internet." In its guide, Linux.com explains each of these processes in detail. While the guide focuses on server backup, each and every command has its place on your personal workstation as well.
What other tools do you use to back up your Linux systems?
This topic first appeared in the Spiceworks Community

try checking relevant environment variables like the CLASSPATH.... a major source of failures in Windows is when in the classpath there is a path containing SPACES.... also enabling some "debug" or "verbose" flag (not sure how to do it) would provide more insight...

Oracle HTML DB Tutorial: Building an Issue Tracking System with Oracle XE

Hello.
I am using Oracle XE and have loaded the sample Issue Tracking System.
I had to set the time-out to 100 seconds as explained in the Oracle XE thread: Problem with importing HTML DB applications (Problem with importing HTML DB applications
I am trying to create users.
The documentation at http://www.oracle.com/technology/products/database/htmldb/pdf/issue_tracking_tutorial_1.6.pdf
on page 82 discusses using HTML DB authentication. However, my understanding is that the HTML DB in Oracle XE currently uses only DATABASE authentication.
Is there any documentation on creating users for the sample Issue Tracking System using Oracle XE?
Thanks!

Ricky,
I am trying to create users.
The documentation at
http://www.oracle.com/technology/products/database/htmldb/pdf/issue_tracking_tutorial_1.6.pdf
on page 82 discusses using HTML DB authentication. However, my understanding is that
the HTML DB in Oracle XE currently uses only DATABASE authentication.Well, in order to log in to the XE management GUI you use the database account. This is correct.
But for authenticating to the application you are going to build, you still have all possible authentication schemes available as in HTML DB (standalone).
Well, you should be able to just go ahead and create the HTML DB users in your workspace (for example HR). In XE a workspace corresponds to an actual Oracle database user, a workspace is created implicitly for the user.
Thus, just go to Home > Application Builder and will find on the right hand side under "Tasks" the link "Manage HTML DB Users".
There you can create the users in your workspace for your application.

PeaceresourceTim we do not have Linux versions of our applications. The WINE environment would also not be sufficient to download, install, license and run the Creative Cloud software.

Linux VI with Runtime Engine Only

Hi,
We're trying to start a VI on a Linux system, with only the runtime engine installed. But we're having a few problems...
First, if the runtime engine installed without errors ("rpm --install labview71-rte......i386.rpm" and "rpm --install labview-rte-aal......i386.rpm") how can I know for sure that it's working? I can't find any file that indicates that it is installed...
Is it possible (just like under windows) to start a VI with only the runtime engine? What should I call on the shell to start a VI?
Is it possible to run a windows VI under Linux, with only the runtime engine? I read somewhere on www.ni.com that to run a VI a rte of the LabVIEW version used to build the VI is needed. But is LV7.1 for Linux the same version as LV7.1 for windows? Is the Linux runtime engine capable of running the windows VI?
In short, what we like to do is: Use windows to develop some VI's with serial communication. Copy the VI's to a Linux system. Start the VI's.
Any ideas are greatly appreciated.
Wiebe.

Wiebe,I wrote that the binary code is OS dependent, not independent.  Please re-check my post (and your reference to my post to rule out cheeky editing.... )Regarding running a linux VI on linux without the development
You're right. Let's blame it on the language barier (on my side), and today being fryday. Still I don't see why assembler code can't be the same on two exactly the same i386 processors. The OS stuff should be handled in the runtime engine, and the add's mul's, call's etc. are the same. But I haven't given in much thought, and never tried anything like that. I'm sure their will be some problems.
environment, I wouldn't know since I've never used LV on linux (yet).  I thought the original duscussion was about running a VI from one platform on another without requiring the development environment to re-compile. 
It was about running a VI on Linux with only the rte. And what's needed to make this happen.
Can't you just build a wrapper VI to call the VI from a built application (provide path and hey presto, it can be called dynamincally.....no?)I also agree that a bit more multi-platform support would ultimately help NI, but I can understand
Yes, if we had an application builder for Linux, we could make a wrapper. It would solve the licensing problem. Perhaps someone can make a Linux application wrapper/vi starter for LV8.2 (we'd be happy with any version though)?
About the support.. Somehow someone forget to put all the Linux documentation on ni.com.
the thinking behind it.  Not that I agree, I just understand Further, I believe the run-time is required to prevent each and every LV application being huge.  But sometimes I wish we could distribute without theis run-time Stigma (or better - have the choice).You've raised an interesting point by questioning the existance of the run-time engine......Shane.Message Edited by shoneill on 02-09-2007 04:01 PM
Someone ought to make a virtual machine that can execute LabVIEW's executable code inside a vi, and simulate the runtime engine at the same time : ) It will take some time though...

I'm going to build a small BSS. (Building Security System) with 10 inputs/outpu

The sugestion from the company is a reliable PLC system. Do you have any sugestions of what hardware to use ? M

Michael,
It really depends a lot on what you want the system to do, how flexible you need it to be, what kind of future expansion capabilities, etc.
From an NI product line perspective, if you are looking at using a PLC you should take a look at our cRIO solution. Like a PLC, Compact RIO has a plethora of different I/O modules. Unlike a PLC, Compact RIO is far more programmable/flexible. It can run a real time operating system with user-programmable FPGA for tight control.
If this seems like overkill for your solution, you might consider something more simple. You could probably get away with some simple digital I/O. We can provide solutions pretty much everywhere in between. You might consider contacting someone in our sales department to talk through your requirements and have them make a recommendation.

How to install JDK on LINUX Ubuntu on system with no net/wireless?

Hello!
I need to install JDK on LINUX Ubuntu on system with no net/wireless connection.
What are the commands?
Thank you!
Edited by: 800512 on 07:29 10/01/2011

- Download your release of choice from http://www.oracle.com/technetwork/java/javase/downloads/index.html
- Put the file on a USB thumb drive
- Mount that drive on the target machine
- Follow the installation instructions.
The Linux/Ubuntu downloads of the JDK are offline installers (i.e. the downloaded file contains everything that's required). Only Windows currently has an online installer (smaller initial download, but requires a net connection for the actual installation)
Alternatively: install the OpenJDK from the official Ubuntu packages using apt-zip (http://wiki.debian.org/AptZip).

Is it possible to build a project with Labview 2010 on a Windows XP system, that is useful for a system with windows 7 on it?

Hi there,
I am planning to use Labview 2010 in a short time.
But before I'm going to use it I have some questions.
I know it is possible to run Labview 2010 in an XP environment. But is it also possible to, when running Labview 2010 on a XP system, to build a project to a version that is useful in a Windows 7 environment?
Or do I have to run Labview 2010, when I want to build a project that is useful on a Windows 7 system, on a system with Windows 7?
Please give me some information.
I hope to hear from one of you soon.
Regards,

Microsoft EOP with Linux System

Hello,
Is it possible to configure Exchange Online Protection, formerly known as FOPE, with Linux system. I am working for an environment where Exchange Server 2013 is located inside the local network and there is a Linux system in the perimeter network, all incoming
and outgoing emails flows via this Linux system.
FYI, we have a plan to remove this Linux system but right at this moment we need to keep it for few months more.
