Ubuntu Installation :: Install Tcl With Non-thread Enabled For Some Other Software
Sep 4, 2010
I have an ubuntu 10.04 system. I have been trying to install tcl with non-thread enabled for some other software. If I install tcl from synatptic or use activetcl, then it gets installed with thread enabled option.
So I thought that I have to compile tcl from source. So i downloaded tcl8.5.8-src.tar.gz file of tcl and extracted it in a folder.I then entered the /unix folder and i ran ./configure --disable-threads and got this output:
I then did sudo make and got:
make: *** No rule to make target `/../unix/Makefile.in', needed by `Makefile'. Stop.

I am going to use "pthread_setaffinity_np" to bind a thread to a specific core. My application has two threads. I have used mutex to assign a specific id to each thread and then bind that thread to a core different from another core. but it seems that the os assigns both thread to one core.What should I do to bind each thread to a specific core?

I have 6GB of RAM and I'm planning to install Fedora 14 32-bit to achieve a higher degree of compatibility. Does fedora automatically download and install a PAE enabled kernel when it detects more than 4GB of RAM (Just like Ubuntu)?

i know i should look more through the forum, but i've been stuck on installing ubuntu on my computer for 3 days now, reinstalling, manual grub installing and so on, but no go. but i found a good thread on my still no fully functional ubuntu computer that explained very well for a complete linux noob how to install grub2 on ubuntu via the livecd. but since i was booting from the live cd meant that i couldn't bookmark it, and very little on this forum, as far as i can see, gets sticky, makes it very hard to find.
the basic problem is, i completly reinstalled ubuntu 10.10, and the bootloader (that i now know is named grub2) could not be installed. so i've found several guides, including the wiki, but it haven't really worked. now instead of explaining all of this over again, like all of you have probably done a million times, can you just post the most informative links here, so i can pick and choose,

I have been trying to find out if there is a driver I can install for my Kodak 5300 aio printer, but the only thread I can find is from 2007, which basically says it's MIA.
Does anyone know if there is one now or not?

Not sure if I have landed in right place for this question .Problem FacedI have 30-40 heavy load (Memory operations on heap) processor running with each having 30-40 threads.In one of the thread (of each process), I have file locking operation as explained below (say in thread T1)Step 1 - Lock the file using fcntl(SETWLK) on file f1, Basically using wait lock.Step 2 - Read/write data from another file f2.Step 3 - unlock the file f1.As the memory occupied by process increased, the swap area used will reduce - this continues for a long amount of period. When the free swap space is reduced to 100 MB free out of 2 G and VIRT reduces to 120MB free out of 17G, for T1 thread, Step 3 is not scheduled for more than 300 seconds after Step 1 and 2.
I want to understand why this behavior is present - as per my understanding scheduling will occur within micro-seconds and we can expect that the T1 thread of all process should be scheduled without too much delay.Additional InfomationMachine Info : (uname -a), Linux linux 2.6.16.46-0.12-smp#1 SMP Thu May 17 14:00:09 UTC 2007 x86_64 x86_64 GNU/LinuxMemory Info :Total Memory is 16GB + Swap Memory is 2GBI want to know why this behavior is observed in SUSE

I'm doing a clean install on a new machine, and when I tried to boot the install DVD, ISOLinux gave me the following error:
Code:
Could not find kernel image: linux After some experimentation, I found that switching the SATA mode in the BIOS from AHCI to Native IDE solved the problem and installation is proceeding normally.
However, I want AHCI enabled. (I think, unless someone has a compelling reason why I shouldn't.) My web-searching suggests that if the system is installed in IDE mode, it won't boot if I switch to AHCI afterwards. Is this a common problem? Is there a workaround? Is it a motherboard issue?

I have recently updated to Ubuntu 10.04 (version of Gnome Desktop environment: 2.30.0, version of Linux kernel: 2.6.32-21-generic).My problem is that when I try to enable "Visual Effects", I receive an error message: "Desktop effects cannot be enabled". When I attempt to enable Visual Effects, my system starts searching for external device drivers but finds none. I don't believe that the source of the problem should lie in my graphics card (I have a DELL Inspiron 1545 notebook with an Intel Graphics Media Accelerator 4500MHD graphics with up to 1750 MB of dynamically shared memory allocated by the system). With the earlier version of Ubuntu, the 9.10, I didn't have this problem.

I just assembled a PC
amd x3 64bit
4 GB RAM
ATI HD4350
Asrock MB
2 HD WD 320 put into RAID 0.
To make this configuration, I have not enabled the raid from bios (since Ubuntu gave me problems) but I followed this guide [URL] (Official guides) to configure software RAID offered by ubuntu. Everything went ok and it works perfectly but when released the 10.04 and the system asks me to update, you think there will be some problem or leaving will be updated throughout unchanged RAID configuration?

I have an old laptop (asus M6 ca. 6 year old) with dual boot linux windows. Untill Saturday linux=suse 11.0, Saturday I have made an upgrade to opensuse11.4.
I have boot up/down many times almot everything was working properly except the battery status ... I have thought .. "I'll think about it later".
Then out of the blue on sunday my laptop does not boot anymore, the boot hangs. I then have realized taht the failsafe boot was working properly.... ok I have remembered the wrong battery signal and tried the normal boot + acpi=off .. and .. it boots!
OK, the acpi is the problem. I have never made an update of my BIOS (this means it is now old), but I do not really want to update it now. with suse 11.0 the acpi was working properly, I have never have touched the acpi boot option and I had all acpi functionality working (battery, suspend .. etc)
how to let acpi work (at least for the main features .. batetry, fan speed, HT ... etc)?
It can be that the old kernel boot was using some "specific flags", (an installation is cleverer than an upgrade ..?!?!) but unfortunatelly it looks to me that nothing has remained from the old installation .. so I do not know ...

I had installed ubuntu, then windows xp, surprise surprise I lost the boot loader for ubuntu. I have 2 different live boot cd's one for 9.10 and another for 10.04. My PC would be running 10.04, if I could install grub. When I go to help on the live boot disk menu, it tells me that rescuing a broken system is not enabled on either disk, though I downloaded a full copy of the disk when I downloaded it. What can I do to get grub back onto my computer? I deleted the XP partition hoping that would help. It didn't now the pc will only boot when I have the live boot cd.

I have a USB stick with a mechanical write protection (a small switch that disables writing on the stick). I have installed Ubuntu 10.04.1 on this device usung the startup drive creator. If the switch is in the position that allows writing, Ubuntu boots as expected. But if I switch to write protection, I only see a blinking cursur. Because it is a live system on the stick I expected that it should work as well, because nothing should be written to the stick. Does anyone have an idea why it behaves like this and how I can change it?

I have a Biostar TA785GE which as I understand it, has a Realtek 8111DL on-board.
Booting with F11 32-bit DVD, and the F12 Live CD crashes before any user input, with indecipherable text on-screen (text mode, not X11).
Symptoms were the same with the Fedora 11 32-bit installation DVD, the Fedora 12 Live 32-bit CD and the CentOS 64-bit install DVD.
Booting with "linux text" mode (w/CentOS DVD) shows a kernel panic in ":r8169:rtl8169_init_one+0x369/0x9d4" from "pci_device_probe+0x100/0x180". I'll have to shutdown again to try the Fedora CD/DVDs, but if there's a different panic I'll post that tomorrow.
Disabling the on-board NIC allowed the boot to proceed, and get as far as detecting the hard drive partitions (where I stopped it since Ubuntu is installed).
Ubuntu 9.04 Workstation(Desktop?) install DVD worked fine, and I've installed it and am using it to enter this.
From Ubuntu 9.04 on this hardware: "uname -r" shows
Code:

Code:
So, my question: if I disable the NIC and install (alongside Ubuntu), will I be able to get the 8111DL working with a Fedora kernel?

I opened a bug for this one in December, but it's not getting much attention as yet, so I thought maybe the crew here could take a whack at it. Here's the text, slightly modified with minor clarifying updates.
Description of problem: When booting from CD burned with Fedora-14-x86_64-netinst.iso, grub starts but when handing off to kernel, text appears in upper left corner of screen and system locks up, requiring power-off to be performed to return functionality.
In testing, grub itself has always worked without visible flaw, and the various built-in functions are accessible (menu editing, command line, etc.). It's just once tries to go any further that it breaks.
Version-Release number of selected component (if applicable): unknown
How reproducible: Always reproducible
Steps to Reproduce:Download Fedora-14-x86_64-netinst.iso and burn to disc Select optical drive from Dell Latitude E6510 notebook from boot options menu Allow boot process to proceed
Actual results: System lock after displaying the following text:
Code:
Additional info: System is running BIOS revision A06 (latest as of today). CPU is Intel Core i7 Q720, and memory total is 4GB. Grub identifies 640K lower and 3,339,004K upper memory (commas inserted for clarity). Windows 7 Enterprise 64-bit installation performed properly in UEFI mode.

i'm trying to understand the POSIX threads and i can't understand when does the thread start: does it start when i do
pthread_create()
or when i do
pthread_join()
or maybe i'm missing something. i do understand that pthread_join() causes the calling thread to wait till the called thread is finished.
