I need to use xdelta tool in my shell script for creating and patching diff files. My PC Linux environment (Ubuntu) has a package installer, and when I try typing xdelta on my commandline, it prompted to try "sudo apt-get install".. after which it directly accessed the packages from the Internet and installed it. So I am able to use xdelta from the command-line in my Ubuntu environment.
I need to also use xdelta on my target. I am using a NFS. The bootloader and kernel are on the target and the RFS is referred from the PC. How can I install the xdelta package on my target so that it recognises the command xdelta. On Ubuntu, "sudo apt-get install", fetched the below packages:[URL]..
I am trying to cross compile php for "arm" target using "arm-angstrom-linux-gnueabi" tool chain. Apache compilation was successful after using a few ac_cv configuration options(and a few others to get rid of compile errors). But was unable to compile php for the target, as the 'apxs' file used was not executable in the build machine.
I tried creating an apxs file for the build machine architecture(intel 686), and using it. It was able to compile then, but still php page is not getting displayed on the web server. (Have done the procedures like, loading the libphp5 module on httpd conffile and all)
I wanted to know how can I cross compile SMS SERVER TOOL for an embedded computer and make just one binary file for it or how can I change all of its default files places like its demon and object file and gather all of them to one directory to execute and use and run.let me explain it better for you : I have an embedded computer with Linux OS that its file system is read only and I can not add any file to /usr /lib and ..... and I can just mount a SD memory card to it and copy all of my programs to it and run them from there as you understand I have two choices to choose, first make one big binary file for each program that I am doing it now and it is not a suitable solution and the second is finding the way to change default place of shared object file of my program.now you tell me what can I do to solving this problem.
I was running CentOs 5.3 and did a "yum upgrade" and got the following problem: Transaction Check Error: file /usr/share/man/man1/xdelta.1.gz from install of xdelta-1.1.4-1.el5.rf.x86_64 conflicts with file from package xdelta-1.1.3-20.i386

It seems that somehow multiple entries were made for the xdelta package - how do I clean this up?
I'm trying to install a SDK iso image onto an embedded linux platform. I was able to mount the image on the platform without problems. I also created a symbolic link called "bash" in the bin directory and had that point to busybox to satisfy the first line of code in the installer: "#!/bin/bash". However, when I run the installer, I get an error: "installer: applet not found"
I get the same error when I type "bash" on the command line. Is there a way to fix this? Here is the first few lines of code that causes the error:
I am running following commands and ist runs fine for me.cp -r /mnt/datasource/* /opt/IBM/WebSphere/DataSource/But if I put this command in script, it does not work.
vi cpydata cp -r /mnt/datasource/* /opt/IBM/WebSphere/DataSource/ #save it
I'm looking for a way to remove embedded features from a PDF document. I recently purchased a Kindle DX. When I try to open some of my PDF files on the device, I get a message saying: this pdf cannot be opened due to embedded features not yet supported by kindleI'm looking for a way to remove the use of these features from the document so I can view it on my Kindle. I'm a Ubuntu Linux user. (I tried opening the PDF in Document Viewer and printing it to a PDF file by going to File->Print. This make it so I could open it on the Kindle DX, but the font is messed up and very difficult to read. This won't do.)
I am using embedded linux (xlinux) and i need to compile the programs on desktop pc.i am currently using eclipse.can someone suggest me how I can configure, to make a project thats compile the programs for the embedded linix where I need to run them.
I am developing a device that will run Linux as its operating system.The device is a small form factor X86 device with a flash drive exposed as a SATA-device. So it is not very dissimilar from any other PC running Linux.For several good reasons I am building my own "distribution", instead of using an existing one.What confuses me is how mount/umount of the root file system is handled.I boot my kernel with the commandline "root=/dev/sda1 rw" which works fine. But everytime I do poweroff or reboot Busybox complained about no /etc/fstab, so I decided to build one.Should I have an entry for my root file system? It seems like this is shadowed by the rootfs anyway. I.e. if I have the fstab entry "/dev/sda1 / ext2 1 1" mount still reports rootfs on / type rootfs (rw)/dev/root on / type ext2 (rw,relatime,errors=continue)My questions are:Do I need to worry? Will the drive be correctly unmounted by the kernel on poweroff/reboot?If I want to perform file system checking on boot, can I do that without resorting to an initrd?
I currently work within an RTOS environment without an MMU and thus have access to the entire memory map of whatever application I'm working on. As is common in the embedded world, different parts of the memory map relate to different peripherals or different types of memory. For our next generation hardware, my company is looking at moving to an MMU-enabled processor and using Linux in some shape or form. Most of us in the dept are familiar with Linux, but we are not Linux gurus by any means. So how to explicitly indicate to Linux that we need certain portions of an application to be stored in NVRam and other portions of the application to NOT be based in NVRam has us confused. None of us have a clear understanding of how user memory is delved out by Linux and how we can influence Linux to use specific portions of the memory map at specific times.
For example in this new application, we expect to have 2 memory chips, both that are DDR3 interfaces. One is a standard DDR3 chip. The other is a non-volatile MRAM with a DDR3 interface so it can be accessed by a DDR3 controller and coexist with conventional DDR3 memory. But because the portion of the memory map that the MRAM will represent will be the only portion of non-volatile memory, we are unclear how we explicitly access MRAM addresses in an MMU-controlled environment. My hail-mary guess was that we would want to somehow tell Linux that we want the MRAM's memory space to be mounted as a RAM Drive and then we access that memory as though it is a file on a HD, except it is much higher speed since it will be at DDR3/MRAM speeds. Is there a better, more straight forward way to do this? Coming from an RTOS world, Linux is going to pose some serious challenges for us, but I think it will be the right move once we are all up to speed and are thinking Linux-centric.
We have designed a board with Cirrus Logic(arm) processor, A Flash memory and some other peripherals have been connected to that. While building kernel we have selected MMU support. We have written few custom drivers for keypad,LED,LCD. But I would like to know how virtual memory mechanism can be helpful here even though there is no any hard disk has been connected. Where will be the virtual memory reside.
I have synology nas box DS710+ that has intel atom processor inside. i've installed ubuntu under virtual box, downloaded needed toolchain for x86 processors, and decided to cross-compile openvpn.
I 've started from compiling lzo library, but first question that appeared in my head - how i have to move all compiled binaries to my synology?
1. configure - okay 2. make - okay 3. make install - this is not necessary?
Will --prefix parameter helps me? or do i have to use chroot? cause there is a plenty amount of files that i need to move to my synology.
I'm using the command below to sync two directories. Problem is insted of deleting the files on the target directory it simply appends a ~ character at the end of the file name. Not sure why this is happening?I'd like to have all deletes on the source replicated on target.
it is not clear to me, by reading different postings/documentations for ntfsclone, what restrictions and/or requirements exist for the target partition (TARGET). Can the TARGET be bigger in size than the SOURCE, or must it be identical? Must the TARGET be formatted as an NTFS filesystem, or must it left unformatted?
I am trying to insert a .ko into my kernel and I am getting the 'invalid module format' error. But the kernel object is being generated from or is included in a binary which sets up and populates a driver path when run. How can I tell what architecture/target/anything that .ko is meant for?
I know that I can use the uname and /proc/cpuinfo to see my current info, but I am also not sure what I might need to do to get them to sync up. I am running on a minimal, cli-install of Ubuntu8.10 right now. It's freshly installed (onto a 2GB USB drive) & imaged, so bring on the drastic changes.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps). We will use Eclipse IDE and C++ lanuage. I hope the tools are easy-to-use, reliable, popular, better with good supports, and not-too-expensive. I already find a list of tools at WiKi, however, I don't have time to try them all. Could anyboy please recommend me a few? If you can tell me briefly about their pros and cons, that will be the bet.
What I am trying to do is edit the link target to force ip=xxxx.xxx.xxx string at end. I have a software program which access 4 different servers running the software but with different configs. In xp I can copy links and modify as above to correctly force the program to the various servers.
I have read the various how tos on hard vs sym links which I get. Playing around with hardlinks and sysmlinks (the examples I find) does not seem to be what I need. Feel like this is pretty basic stuff but I am a bit stumped.

I'm trying to solve an intermittant serial port problem on an embedded medical monitor. We have determined that the port is receiving characters from the external device but the serial thread is not transferring the chars from the buffer. Has anyone seen this before? Looking for some guidance on what to look for. this problem happens at start up about 1 in 50 boots. We're using kernal 2.6.29.6.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps) with ARM-based processor. We use Eclipse IDE and C++ lanuage for development. Does anybody have recommendation for tools to analyze code complexity? The tools is better to support McCabe complexity metric, however, we may also consider others. Does anybody have recommendation for unit testing?
I'm trying to run a shell script on a kern board (av1100) that shows some text output on the attached screen. The big problem is that the screen goes to blank in like 2 minutes.I'd just like to have the script showing it's output while the thing is on.Isn't there a command to stop the screen from going to blank?p.s. there is no bash available, just #!/bin/sh
