  • embedded web browser

    - by Ilya
    Hi, I'm looking for Linux embedded web browser, or preferably just a rendering object (it will not be used for actual browsing, just for displaying web based gui). The requirements are: Written in C (small footprint) Support Dynamic HTML Support Java script Minimum dependencies on the libraries (although i understand that it can not be completely standalone) No Dependency on X11 (i.e working with direct frame qui libraries) So far i only found Embedded Konqueror. Any suggestions are welcomed, commercial solutions are OK, but open source is preferable.

    I want to learn how to write shell scripts. Particularly I want to write a svn post-commit script to upload files from a test server to a production server. I am sure I will want to write more as I get more into it. I have very little linux/unix knowledge. Can anyone recommend a good book?

  • Converting jiffies to milli seconds

    - by EpsilonVector
    How do I manually convert jiffies to milliseconds and vice versa in Linux? I know kernel 2.6 has a function for this, but I'm working on 2.4 (homework) and though I looked at the code it uses lots of macro constants which I have no idea if they're defined in 2.4.

    I'm trying to create something that will be playing some sound and music for some things in Mono+C#, but I'm not sure what the best thing will be for that. I'm trying to make it usable with things like Ogg Vorbis, MP3s, and wave files. My primary platform will be Linux, although a cross platform solution would be nice. Anyone have any suggestions for libraries for playing audio files?

  • Getting the DLL name from a mingw32-compiled lib/a file

    - by epsy
    Hi, I am changing our build system in order to handle cross-compiling and packaging. It is a common thing to ship dependencies' DLLs but CMake's FindXXX modules(./configure checks) don't provide the path to these DLLs but only to .a files. I quickly looked inside the .a libs and they all seem to contain the DLL's name. What would be a proper way of extracting them from the .a file on a Linux build machine?

  • POSIX: allocate 64KB on 64KB boundary.

    - by Eloff
    I would really like to actually only allocate 64KB of memory, not 128KB and then do the alignment manually - far too wasteful. VirtualAlloc on windows gives precisely this behavior. Supposedly there's code in SquirrelFish for doing this on just about every platform, but I haven't managed to locate it. Is there a space efficient way to allocate 64KB on a 64KB boundary in POSIX? Failing that, in Linux?

  • How can I find the size of a ELF file/image with Header information?

    - by fasil
    I need to find the size of an elf image for some computation. I have tried with the readelf utility on linux which gives the informations about the headers and section. I need to have the exact file size of the elf(on the whole). How do I find the size of the ELF from the header information or Is there any other means to find the size of an elf without reading the full image.

  • Low level Android Debugging

    - by L4N0
    Is there a way to trace through function calls at the lowest levels of the Android system? Right now when I debug in Eclipse, it goes through the source files that are located inside the frameworks folder, but is it possible to go even lower? For example show what functions are being called from the libcore folder. I am also interested to find how it communicates with the linux kernel at the bottom of the layers. Is there a way to do this? Thanks

  • Deleting a possibly locked file in c

    - by Moev4
    I am using fcntl locks in C on linux and have a dilemma of trying to delete a file that may possibly be locked from other processes that also check for the fcntl locking mechanism. What would be the preferred way of handling this file which must be deleted, (Should I simply delete the file w/o regard of other processes that may have reader locks or is there a better way)? Any help would be much appreciated.

  • What does an empty run queue entry points to?

    - by EpsilonVector
    I'm trying to figure out the technicalities of scheduling in Linux. What I can't figure out is what happens with those entries in the run_queue where there are no running processes. In the run_queue we have a bitmap, a counter, and the array of lists themselves. For a list that is empty because there are no running tasks with its priority, what do the next and prev pointers point to?

  • Displaying an image from the tmp directory

    - by Roland
    I have the following. A website that create temporarily images in the /tmp folder on the Linux server. The reason why I store it within this folder is since these images need to be cleared once in a while and it's so much easier just to clear the tmp directory using tmpwatch. Now my issue is to display the image within my browser? Code <img src="/tmp/3d34636.png" alt="image" /> I'm running Centos with PHP

  • stderr to file; but without buffering

    - by l.thee.a
    I am trying to isolate a nasty bug, which brings down my linux kernel. I am printing messages to stderr and stderr is redirected to a log file. Is there a way to disable buffering on the file access? When kernel hangs, I am losing the messages in the buffer.

  • Can I automate the finding of -l parameter I use when linking based on header files (gcc)?

    - by kavic
    Normally when linking against a static library, I have to specify a library directory and the name of a libX.so (or its symbolic link) as -lX flag for linking [and its directory with -L flag]. Can I automate this based on my header files (in c/c++) only? Or maybe it is not a good idea? Is there a software for locating the -L and -l parameters automatically? Is some table stored somewhere on the system about this on popular linux systems or even cygwin?

  • Using Python to add/remove Ubuntu login script items

    - by codebox_rob
    I have written a Python application and would like to give my users the option of having the app automatically launch itself when the user logs in. It is important that the user is able to toggle this option on/off from within the app itself, rather than having to manually edit login scripts, so this needs to be done from within the Python code rather than from a shell script. The app is deployed on Ubuntu Linux, any suggestions for the best way of doing this?
