Ubuntu :: Enabling Parallel Compilation Of Kernel Source?
Sep 17, 2010
enabling parallel compilation of kernel source.I've read that setting the CONCURRENCY_LEVEL environment variable should do that. The problem is that I see only one instance of a running gcc in top, notwithstanding I have set "export CONCURRENCY_LEVEL=5".
I created a customized version of a package, and when I did an upgrade later the source build got overwritten.How can I configure the package system to stop that from happening even if the main repositories have newer versions?
compiler problem (f77) which arises when I try to execute a bash script ("compile" see [1] below) running under Cygwin on WinXP. The script finds the correct file(s) but the compiler does not recognize them as fortran source files. If the script is executed sequentially from the command line then there is no problem.
The directory structure of flh971da contains two subdirectories flh971da/scripts and flh971da/source. The compile script [1] is shown (in part) below. The script changes directory to flh971da/source, and compiles source from subdirectories flh971da/source/n where n=a,b,c etc and places the object files in flh971da/source/nobj n=a,b,c... etc. The response to flh971da/scripts/compile script is given below [2]. It is clear that the compiler (f77) locates the correct source file [4] (flh971da/source/a/a00aaft.f) but does not recognize it as a fortran source file. All relevant files have been processed with d2u. I suspect the problem is with the script, but I have no idea how to fix it.
Just I compiled Kernel xxx.3.6 in ubuntu in Virtual Machine for 32 bit. However, I wanted to do it for 64 bit, I dont know what parameter is necessary for 64 bit.
I noticed (the hard way) that enabling a guest session under 9.04 does not lock the source user. I enabled a guest session for someone and came back to find them rooting through my files. By quitting the guest session, it goes back to the source user's desktop without requiring a password. Shouldnt it go to gnome-screensaver automatically? Can this be changed? Is it a bug?
to replicate: log into source user's account use the menu to start a guest session quit the guest session root through files un-opposed.
Is there a startup option I can put in the /etc/init.d/mysqld script or an option in the /etc/my.cnf file to enable the Archive engine for MySQL or do I have to compile it from the source?
i am already a little bit familiar with linux and now i want to know better the linux OS. i have downloaded the source code of the krnel from the kernel.org and i dont understand the linux source trees organization, so can somebody do me a favor and give me a link to some internet page (or at least a book) that explains that?? i have searched in the internet with the tag:::linux source trees organization and i have not found nothing interesting
I'm trying to get a fedora guest running reliable smp under VirtualBox 3.0.6. The VirtualBox manual says "Some Linux distributions, for example Fedora, ship a Linux kernel configured for a timer frequency of 1000Hz. We recommend to recompile the guest kernel and to select a timer frequency of 100Hz." So I tried recompiling the kernel. Being a responsible lad, when it came to setting the kernel specs:
Code: # Polite request for people who spin their own kernel rpms: # please modify the "buildid" define in a way that identifies # that the kernel isn't the stock distribution kernel, for example, # by setting the define to ".local" or ".bz123456" # # % define buildid .local %define buildid .rim_for_vbox I've successfully built and installed kernel, headers and firmware:kernel-2.6.30.5-43.rim_for_vbox.fc11.x86_64.rpm kernel-firmware-2.6.30.5-43.rim_for_vbox.fc11.x86_64.rpm kernel-headers-2.6.30.5-43.rim_for_vbox.fc11.x86_64.rpm The system is working fine (well, so far). But trying to install the VirtualBox Guest Additions kernel add-ons still gives me
Please install the build and header files for your current Linux kernel. The current kernel version is 2.6.30.5-43.rim_for_vbox.fc11.x86_64. I'm pretty sure this is because my kernel doesn't match the development packagekernel-devel-2.6.30.5-43.fc11 (x86_64). So the key question is, how on Earth do I create a development package to match the responsibly-renamed kernel?
Why it asking me for options to be selected while I run: Code: make oldconfig.I am in verse to compile latest reased kernel 2.6.34-rc5 on Ubuntu 9.10?what i did is Just pressed "Enter" key ( i think it will dsiable everything?Not sure) and created a .config file.
I'm simply trying to compile a vanilla kernel from Kernel.org, I've done it before, however "make menuconfig" returns an error after I've made my changes to the config file.
Code:
Why is make returning that error? I am using a 64-bit kernel.
I've been reading about a temporary solution to the kernel/Fglrx issue caused by the last kernel update, but I haven't read about any permanent solution to this issue. Anyone know anything about a permanent solution (new kernel update?, new Fglrx driver?) to this compilation error?
I'm trying to get Virtualbox up an running. So I have added virtualbox in my repo and added the key, looks fine so far. but afeter downloading I get this:
VirtualBox-3.0.8_53138_rhel5-1.x86_64 Creating group 'vboxusers'. VM users must be member of that group! No precompiled module for this kernel found -- trying to build one. Messages emitted during module compilation will be logged to /var/log/vbox-install.log.
Compilation of the kernel module FAILED! VirtualBox will not start until this problem is fixed. Please consult /var/log/vbox-install.log to find out why the kernel module does not compile. Most probably the kernel sources are not found. Install them and execute /etc/init.d/vboxdrv setup as root.
It sounds like he's making a difference between the kernel "source code" and the kernel itself(as in the downloaded file/ files) but the way he talks about both is the same.So then, if one had already "installed" the "kernel sources code," why would he need the "tarball with the newest Linux kernel?" He's already "installed" a kernel, right?
Trying to install virtualbox in F12 but fails when recompiling kernel module. Output of vbox-install log is:

I am running an Hp Pavillion dv6000 with the Broadcom card that never seems to work for Linux. I recently talked with my friend who said he found a way to get it work.following his instructions I opened Synaptic and checked the package bmcwl-kernel-source to be installed.I went through the process of it all and it said it had install successfully. I restarted the computer and when I tried to enter my operating system I got this error "Kernel panic - not syncing : VFS : Unable to mount root fs on unknown - block(8,1)" I have previous versions of Linux on my computer so I can still get in to those if need be but I don't know how to undo what I did or why it isn't working for that matter. Does anyone have any ideas as to why I am getting this error and how I can fix it?
I've been trying to install nvidia drivers yesterday, so I went to runlevel 3, ran the .bin installer and it came up with error: missing kernel-devel and kernel-source.
So I go yum install kernel-devel, it does, but it doesnt find anything like kernel-source.
How do I fix this issue? I have Fedora 12, and I ran drivers from:[URL]..
I installed the latest kernel liquorix (2.6.35) but when i want to install the Nvidia driver downloaded on the Nvidia website (256.53), i have an error message because Nvidia doesn't found the kernel source tree.
I install linux-image-2.6.35-6.dmz.2-liquorix-686_2.6.35-16_i386.deb, linux-headers-2.6.35-6.dmz.2-liquorix-686_2.6.35-16_i386.deb and build-essential. I don't understand why the installation doesn't works.
I'm running CentOS 5.3 and would like to know what the "best" or "proper" method is to build a custom kernel using the generic kernel sources from kernel.org. Most of the references I've found talk about modifying the current CentOS kernel using the RPM way. I really want to have the latest kernel due to some important security issues that haven't been addressed in the current CentOS 5.3 kernel.
I have installed the fedora 14, but there is no kernel source tree.I read the doc "building a custom kernel".But I don't want to rebuild a new kernel.I just want to install the source tree of current kernel.Could someone tell me the way?
I was trying to install VPN client for my Ubuntu 9.10 64-bit. During the installation process the terminal reads:
"Directory containing linux kernel source code [/lib/modules/2.6.31-21-generic/build]"
On that I pressed enter for the default option (in bold). After a few more steps I reached the following error:
Making module sh: Can't open ./driver_build.sh Failed to make module "cisco_ipsec.ko".
[/lib/modules/2.6.31-21-generic/build] is the location where the installer expects the kernel source to be (I am guessing). So unless I correct the terminal (by providing the location of the kernel source), I think I will keep on getting the same error message.
So to get the kernel source I visited: [URL]From there I copy pasted the command:
Code: apt-get source linux-image-2.6.32-21-generic Reading package lists... Done Building dependency tree Reading state information... Done Picking 'linux' as source package instead of 'linux-image-2.6.32-21-generic' NOTICE: 'linux' packaging is maintained in the 'Git' version control system at: kernel.ubuntu.com/git-repos/u...untu-lucid.git Need to get 86.7MB of source archives.
