I have written a PCI LKM device driver that compiles and loads correctly via #insmod libfoo.ko. When # dmesg | less is run I get good results and no errors in the log. The LKM header file is visible in the eclipse workspace.how do I attach (link) this loaded LKM in a eclipse project so that the LKM driver functions are visable?
View 2 RepliesI have set up Eclipse + CDT on an Arch 2010.05 install. I set up an eclipse project and added SDL as a dependency (see below):
Project -> Properties
* -> GCC C++ Compiler -> Preprocessor -> main=SDL_main
* -> GCC C++ Linker -> Libraries -> SDLmain SDL (in that order top to bottom)
* -> GCC C++ Linker -> Libraries -> Library Search Path -> /usr/lib/ (I verified that libSDL.a and libSDLmain.a are there)
This is the code I'm compiling. It's designed to just be a hello world style SDL app to see that everything is working.

I recently installed Fedora 12 and attempted to create a new java project in Eclipse.I used the 'eclipse' command in the terminal to start eclipse. It starts fine, however, there is no 'java project' option after choosing 'File->New Project'. Only CVS and General projects. I am not experienced enough in programming to understand the relevance/usage of either of these project modes, and only want to be able to write java programs in Eclipse.
Also, does the eclipse that is run from the terminal support c++ development? I have attempted to download eclipse for C++/C developers, but cannot get it to run. Which eclipse is running when I type 'eclipse' in the terminal? Is there a way to make it so I don't have to run this command from the terminal to load eclipse?
I'm starting work on a little project that uses alot of languages separately (i.e no interaction between languages. Does anyone have any experience like this and could pass on some recommendations as to best practises? I'm thinking either have a eclipse-project for each language stored under a single svn repo, or individual projects for each problem.

View 2 Replies View RelatedI have recently trying to build an Accounts system database for a project. When you run the program it goes in the main menu sort of like this.
Accounts System
Add a Customer With a Contract......1
Add a Customer Without a Contract...2
Display all Customers...............3
Find a Customer.....................4
Edit a Customer.....................5
Print a Statement...................6
Print an Invoice....................7
Load File...........................8
Save and Exit.......................9
When you add a customer with a contract, you add name, address, start contract, end contract, payment and email address. Now, is there a code I could write to get back to this menu. To not confuse anyone, all I just saying is supposing I accidentally push number 1 on the keyboard and suppose I didn't want to add a customer. In other words I need a code that can cancel (or stop) adding a customer to go back to the accounts system menu.

Logical Memory Space of 4GB is divided in to 3GB User Space and 1GB Kernel Space. Always. Correct?
1. How can we change it? (just changing value of PAGE_OFFSET is okay?)
2. If system have only 256MB of memory (embedded system) and suppose Kernel Modules eat away all the memory during boot. User space will be left will no memory. Is this case possible?
I didn't do enough research beforehand and just discovered that while gcc 4.1 is still packaged, g++ 4.1 is not. I am working on a project with unsupported libraries (don't ask) and can only build successfully with g++ 4.1.*I see that there are packages for Lenny. Is it safe to install these under Squeeze?Being new here I am not sure where else to look for third party packages is, so if anyone could point me in the right direction that would be great. I'd very much prefer not to try to build from source as I'll almost certainly clobber my 4.4 install in the process.

View 1 Replies View RelatedIt's been a very long time since I did much C development and I'm trying to contribute to a PECL extension for PHP. PHP and the PECL extensions are written in C and I'd like to set up my dev environment so that I can use a nice IDE (like Eclipse) and debug my code, stepping through it within a nice GUI. I'm hoping to develop on a linux box (Ubuntu 10) rather than Windows.
The main issue I have is that I don't know how to configure Eclipse (with CDT) so that it runs the entire process: configure/make/make install and then allows me to step through my code within the Eclipse GUI IDE. I have managed to edit files and then build from the command line and then use GDB to step through the code, but that's *REALLY* tedious.
Also, the PHP source codebase is quite large and takes several minutes to build. I'm hoping I might be able to limit the build to just one particular extension rather than rebuilding the whole things. Lastly, I'd like to avoid installing the new, possibly broken, code in order to run it. Unless I'm mistaken, the build process results in a binary being constructed in the source directory and I'd like to debug using that new binary before I bother to install it on my system. Sorry if these questions seem really basic. Like I said, it's been awhile and I'm hoping to get back on the horse quickly.
On Debian, if I want to compile some package X myself, but I don't want to spend time hunting down and installing its dependencies, I can issue the following command:
Code:
apt-get build-dep X
And apt (so long as it knows about package X) will install all the dependencies for me.Does the yum package manager on RedHat-based systems have a similar feature?
I have an init script running as a special build user which performs an automated build that fails with (Too many open files).I updated /etc/security/limits to allow the special user more open files, but that didn't work - the init script still isn't allowed more open files.Here's a demonstration of the problem;

I have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
Code:
x86_1$ make
gcc -O3 -c jpegloader.c
gcc --std=c99 -O3 -c --std=c99 -I/usr/include -L/usr/X11R6/lib main.c

Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.
My team member want to use "mknod" command for build root file system of our project...
But, mknod is only excutable by "root".
I don't want to let them know the root password.
I think that "sudo" and "fakeroot" are the way to use mknod...
Except for those command, are there any way to use "mknode" ?
OR
Is there any solution for make "root file system ?"

I am developing a I2C CDROM client driver. The CDROM firmware supports TOC information read through a I2C command. It sends the TOC information in burst ( Interrupts a GPIO pin when it is ready ) and my CPU does a I2C read to read the TOC. When the CDROM firmware finishes sending the last data burst , it informs my CPU that it is done with the TOC, by a flag in the last data burst. I would like to know, which is the most efficinet way I can send these TOC information to userspace?

In a 32-bit system, max memory addressable is 4GB. Now Linux kernel does memory mapping division of 1GB for kernel address space and 3GB for user address space. That means 4GB of virtual address space is divided between kernel (1GB) and user (3GB).
Q1. All virtual mapping utilizes the available physical RAM without any division? I mean to say that if RAM is 512MB then a page in kernel space can lie any where RAM (leave aside old PCI dma accesses)? (How this fits to fact that kernel memory is non-pageble)
Q2. If a process is created in user space, it has visibility 4GB address space or 3GB address space?
I have the following requirement in my module. The driver gets some data from the external device. After getting 1MB of data it has to send it to the user space application. What is the best thing to implement for this in driver.? Is it ok to implement like, after getting data, the driver will send a signal to the user space application. Then the user space application sends an ioctl to read the data. Is there any alternate, that the driver directly sends the data without the user space application asks for it.?
