I am an intern who was offered the task of porting a test application from Solaris to Red Hat. The application is written in Ada. It works just fine on the Unix side. I compiled it on the linux side, but now it is giving me a seg fault. I ran the debugger to see where the fault was and got this: Warning: In non-Ada task, selecting an A...
I’m interested in using libhid to access a custom HID device that we are developing on a PIC microcontroller. I have been able to successfully get the test_libhid code to run. The instructions for reading and writing to devices using this library are provided as comments in the test_libhid code. I have attempted to follow the document...

I am having trouble with Linux spacing of things, in multiple APIs. Thoughts? On the linked page below, there is a button with a magnifying glass on the map - in the upper left corner - directly to the right of the Home Map button.

I'm writing a C program for OS X and Linux, and I want to tweak the output based on whether or not it's going to a terminal. I know we've covered how to do this in a shell script, e.g. here: http://stackoverflow.com/questions/911816/detecting-the-output-stream-type-of-a-shell-script But how do I do it in a C program? ...
I want to sharpen my skills in terms of gnu/linux and get a better understanding of how servers work. So I thought I'd set up an apache webserver with ftp, ssh, svn etc. Since I use Adobe products everyday in my line of work installing a linux dist. straight on my machine isn't an option. Yes, I could probably do a dualboot with linux an...

In my driver's file_operations structure, I have: struct file_operations Fops = { read: device_read, write: device_write, unlocked_ioctl: device_ioctl, ... }; I.e. there is no ioctl field used. Is this sufficient to avoid Big Kernel Lock and enter into device_ioctl() without any synchronization? Or do I have to change i...
Compiling a kernel module on 32-Bit Linux kernel results in "__udivdi3" [mymodule.ko] undefined! "__umoddi3" [mymodule.ko] undefined! Everything is fine on 64-bit systems. As far as I know, the reason for this is that 64-bit integer division and modulo are not supported inside a 32-bit Linux kernel. How to I find the code issueing th...

The idea is that the user follows a menu to choose a site and then the system starts gFTP full screen (1024x768 or 1280x1024) and when this exits it closes X windows and logs off. Now all I need is making gFTP start with a prescribed size and its done. I've tried to c...
From pthread_join() man page: When a joinable thread terminates, its memory resources (thread descriptor and stack) are not deallocated until thread performs pthread_join on it. Therefore, pthread_join must be called once for each joinable thread created to avoid memory leaks. Does it mean I need to join each thread I create to pre...
We have a set of Mac machines (mostly PPC) that are used for running Java applications for experiments. The applications consist of folders with a bunch of jar files, some documentation, and some shell scripts. I'd like to be able to push out new version of our experiments to a directory on one Linux server, and then instruct the Macs t...
