Fedora Hardware :: Run At 1920x1200 - Error: Building The VirtualBox Guest Additions Kernel Modules [FAILED]

Jan 31, 2010

I opted to install my Linux Fedora distribution, in a SUN VM (Virtualbox). [URL] I have 2 questions:

My current max res available to select is 1024x768. Can I run at 1920x1200? My display indicated that it is 'Unknown'. I don't know if that is in on the deal, or not...

Second question: When installing VBOXADDITIONS_3.1.2_56127, I am getting the error: Building the VirtualBox Guest Additions kernel modules [FAILED]

If I am displaying the log correctly, it indicates: Makefile:23: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.. Stop Pictures are located here, in the EVGA Linux forum: [URL] I am new to both Linux, and Fedora.

My mission statement: To run Linux using the Fedora distribution, in a VM window under Windows 7 64bit Ultimate, with the ability for scripting using Bash, with the Perl programming language installed, and use Apache Tomcat to monitor both apps, and various VM installs, on numerous Servers via the internet.

Programming :: Using SIGNALS In Kernel Modules?

Apr 23, 2010

I am writing a kernel module which need to do something at some interval. Now this problem can be solved by using a user process, which will send signal to the kernel and the kernel would do accordingly. But it would be nice, i could do it within the kernel module itself. Is there any way to use SIGNALs inside the kernel module?

Debian Programming :: Building Kernel Module

Dec 8, 2013

I'm trying to build the kernel module for dvbhdhomerun. The problem is the linux kernel headers provided by Debian do not have the dvb header files. Trying to set up my own kernel source tree to use is not working out so well.

I'm following the instructions in the Debian section here: [URL] ....

My first try compiled, but the modules ender up under /lib/modules/3.2.51/extra instead of /lib/modules/3.2.0-4-amd64/extra. Why?

I tried to start over, but noticed this while running apt-get source linux-image-3.2.0-4-amd64:

Code: Select allReading package lists... Done
Building dependency tree       
Reading state information... Done
Picking 'linux' as source package instead of 'linux-image-3.2.0-4-amd64'
NOTICE: 'linux' packaging is maintained in the 'Svn' version control system at:

[Code] ....

The failure to verify the signature has me concerned, but beyond that, what do I do about the different version number when compiling and installing the kernel modules?

Programming :: Avoiding Global Variables In Kernel Modules?

Jun 27, 2010

I have two modules A and B in the kernel which i am trying to hack by introducing a variable in A which is of type 'extern' (and using EXPORT_SYMBOL) and then calling it in B. Now the problem is how to introduce that variable in module A. Currently i have made a global variable and it works fine but global variable in kernel is a bad bad thing.

I tried having an 'extern' function in A which have that variable and calling that function in module B, but then again how would module A use my variable unless the variable is available outside the scope of that function and that again means a global variable.

OpenSUSE Hardware :: Building MCS9865 Driver - Cannot Make Target Modules

Jul 14, 2010

I recently bought a pci multi io card to give my pc 2 parallel ports. For Linux, Moschip supply the source plus makefile and instructions. I ran make as root and got an error message
make: *** /lib/modules/ No such file or directory. So I created a folder called build in /lib/modules/ but that isn't good enough as I still get an error cannot make target modules. So I assume there must be something in the build folder. So what packages do I have to install to get the correct environment to be able to build the driver? Has anyone done this and can supply the driver for 11.2?

Ubuntu Multimedia :: ALSA Driver Install Failed At Building Modules

Oct 10, 2010

I am attempting to install the Linuxant ALSA driver to make my sound work properly (speakers muting when headphones plugged in). This worked on Lucid, but on Maverick the installation fails at the "building modules" stage. It directs me to a logfile, which I have reproduced here:

rm -f .depend *.o*
rm -f modules/*.o modules/*.ko
rm -f *~ out.txt *.orig *.rej .#* .gdb_history
rm -f doc/*~
rm -f config.cache config.log config.status Makefile.conf
rm -f utils/alsa-driver.spec .....
make[1]: Leaving directory `/usr/src/linux-headers-2.6.35-22-generic'
make: *** [compile] Error 2

The package partially installed I have no sound at all. I have kernel headers and every related -dev package I can think of installed. I'm running 64-bit; could that be an issue?

Programming :: Build Module Against Headers That Are Not From Running Kernel?

I'm trying to debug a module I programmed but I don't want to do it on the running host but against UML (don't want to reboot every 5 minutes).

The UML kernel I downloaded is I have already downloaded the ubuntu kernel headers for this version (they belong to natty though I'm running maverick.... when I installed the .deb file with dpkg I had no problem at all).

Now I'd like to build said module against these headers. How can I do it?

General :: New Kernel Only Has Two Modules?

I have just compiled a new kernel. When I boot into this new kernel and do an lsmod it is only running two modules.

I am running Ubuntu 10.04. The new kernel is The kernel seems to work fine but I need to know why and how it can only be running two modules.

Fedora Installation :: New Kernel Will Not Boot (Modules)

Mar 26, 2011

The new kernel upgrade on Fedora 14 will not boot. lib/modules do not exist is the message. Grub was adjusted to match the old kernel, and the new kernel when booting says lib/modules do not exist. The old kernel has twice as many modules as the new kernel in lib/modules. How do I get the new modules to install so I can boot with the new kernel then? Should I reinstall the new kernel?

Is there a nice easy way, to remove all of the sources, there, and err "install" the ones for my latest kernel, in the correct places. Then I might have a chance at getting the two modules I need complied! Nvidia being one for the geforce 4 mx420 nv17
