Get arch x86_64

When i write "arch" in the terminal, i get i386. I try to write : sudo env ARCHFLAGS="-arch=x86_64" and still after i386. How can i change the i386 architecture of my cpu to x86_64 in Mac OS X10.6.3?

Here's a reply I made some time ago about this subject.

Automated install Arch x86_64 root-file system the "Raspberry" way..

Dear Archers,
I am currently deeply interested in installing Arch as dual boot on my
current x86_64 system.
And yes, there is plenty information regarding this subject in Arch wiki's.
However...
I would like to automate the installation the "Raspberry-Pi" -way.
Details on the "Installation tab" of:
http://archlinuxarm.org/platforms/armv6/raspberry-pi.
As you can see, the installation steps are easy to automate, in my opinion.
That's why I wrote an automation script for this purpose..
The information further suggests that there is a root-filesystem for
Arch named: 'ArchLinuxARM-rpi-latest.tar.gz.'
Unfortunately, I don't think this root system will function on x86_64 systems..
So I researched if there was a root filesystem for Arch x86_64 and found filenames like 'root-image.fs.sfs' 'core.db' 'core.img'.
But I'm unsure if these archives/images really contain a rootfilesystem similar to the ArchARm system.
Therefore my question:
Does anybody know if there is a similar root filesystem for x86_64 so I can reproduce the "rpi-way" installation for x86_64 systems?
Kind regards,
Kees Epema

You are definitely not going to be able to simply dd arch to your machine unless you create an image to do so. Even then, that image would become old and stale pretty quickly, possibly leading to problems getting the system up to date.
In my opinion, the raspberry pi way to simply dd'ing an image to an SD card is a disservice to the ArchlinuxARM users. Though seemingly the proper way to get a system running on a raspberry pi, it masks the install process and leaves the user without a clue as to what would have gone into creating the system.
Go read the beginners guide. Use a virtual machine to practice if you need. Shortcuts are not going to help you with Arch.

[SOLVED] Fail to boot Arch x86_64 live CD on a HP laptop

Hey, guys, what's up?
Well, here's the thing: I bought a new laptop a couple days ago and I'm kind of having some trouble. Its a HP Pavilion dm4-1063cl (this model: http://www.notebookcheck.info/HP-Pavili … 579.0.html, just in case).
I ran some tests in Windows 7 about the architecture of the processor and it clearly seems that it can support arch x86_64 bits. However, I tried to boot Arch x86_64 by a Net Installation CD and it doesn't work. The process fail in the "Loadin UDEV events" phase, something like that. PS: the i686 image boots perfectly.
Then, I thought that was the CD I burned the reason for trouble - I did not check md5sum and stuff like that. So, I burned another dual image (with boths i686 and x86_64) and tried to run again the 64bits kernel. It did not work in the same phase.
The only response I get is a dark screen that never seems to go away. It was a panic I've never seen before with Arch Linux.
The only alternative I can think right now is trying an older version of the live image CD and see what happens, but it doesn't seem like a very good option. Any ideas?
Hope someone of you can help me. Here in Brazil, most of computers we buy come with Windows installed and we don't have quite a chance of not getting - or paying for - it. I'm sure I'll have such a trouble installing dual boot with Arch Linux, but I really miss my Arch Linux...
And, damn, I worked too hard to get a new processor. I really dont wanna use Arch i686 on a pc with x86_64 architecture, it seems like an option, but a dumb one. =p
Cheers,
Wilson.
EDIT: It turns out that tt was not a kernel panic as I thought. The kernel changed the resolution of the display during this fase, and somehow it doesent work.
The trick I used to solve this was adding "nomodeset" to the kernel line in the Live CD booting. Btw, you can do it by selecting the booting option you want in the live CD and pressing TAB. Then, you can edit the kernel line. (:

HP DM4-1265, Intel Corei5, Intel Graphics. (Two days old, windoze wiped, Arch installed)
At boot the brightness is, for some unexplained reason, set all the way down to 0 on these intel based DM4 laptops. A few simple <Fn>+<F3> turns the brightness back up.
To solve this I had to put this in rc.local -
echo 6 > /sys/class/backlight/acpi_video0/brightness
you can enter it manually to test first (as root). Try to turn your brightness up and down with it to make sure it works.
My fan ran like crazy too. HP chose to default a BIOS setting that keeps the fan running constantly. I disabled that and all is well. Fan only comes on when needed and lm_sensors shows my temps, right now, at 43C. Ambient is at 77F right now (I'm in Florida) and this kick butt Arch laptop is, in fact, on my lap.....
Don't give up man.
First of all: thanks for replying.
I installed manually the "coretemp" kernel modules and lm-sensors now give some different response. The script "sensors-detect" does not find any answer.
Looks like the temperature run in a regular level (50º-60º), which I consider a good sign. However, sometimes when I use arch for 24h+, it shuts down suddenly and does not let me boot my computer again - I believe it is a overheating problem. Happened a couple times, big no big deal.
On the other hand, in Windows 7 I have no trouble at all. The temperature goes around 40º with some daily activities. It worries me out because I used - and I do use - largely and successfully Arch i686 version in crappy notebooks with no heating at all.
I tried some tweaks in the rc.local, but none of them seemed to really work. With cpufreq, I could slow down the processors and maintain a regular temperature. Looks like I can list some of the fans speed in the /sys/ files, but much of them do not seem to have any change at all. Some of them looks like to have some "max_state" set to low values like 1, but most do have a limit like 10.
I will keep trying. If there's anything new, I'll post here

Automatically tagging arch=(x86_64) to PKGBUILDs in yaourt?

Every time I get a package from the AUR, I need to manually edit it to add the arch=('x86_64') string so I can get packages to install. Is there something magical I could to to put that string in the PKGBUILDs, as well as make me a burger? I am really hungry.

Tom's got a point - if you find a package missing x86_64 as a supported arch, and you can build and run it fine on your system, let the package maintainer know so they can add it into the PKGBUILD.
In any case, this is a bit hacky, but will probably work:
#!/bin/bash
# makepkg64.sh - add the x86_64 arch as supported, then make the package.
[ -f ./PKGBUILD ] && echo "arch=('x86_64')" >> PKGBUILD
makepkg $@
cat << EOF
Here's a juicy hamburger:
.' o '.
/ o o \
|o o o|
/'-.._o __.-'\
\ ````` /
|``--........--'`|
jgs `'----------'`
Eat it while you tell the upstream maintainer whether this package works or not.

Getting Arch to see the card

I just got a Thinkpad R50e and have been trying to get Arch to work with Wifi on it (it uses the ipw2200 driver). I've got the modules all installed and loaded and stuff, but Arch doesn't seem to see the device:
[root@mezzanine zero]# ifconfig -a

It's only detecting my ethernet card. I find this really weird because Debian and Slackware both see the wifi as eth1 when I do ipconfig -a and a previous installation of Arch I had on here (yesterday -- I borked it by accident and reinstalled) was able to see it.
How do I get this install to see it?

OK, assuming the patch posted there fixes the problem, the only problem before you is how to patch?
If that's the case, you should first download the patch content posted on the AUR page and save it with the given filename, i.e., vmblock-9.0.2-5.0.2-3.12.patch
Then put the filename in the sources field of the PKGBUILD and put the file's md5sum in the respective field of the PKGBUILD as well.
After that, run
$ makepkg -si
You might want to read the following for reference:

Arch x86_64 won't boot, but i686 will. Live USB and HDD.

To be more succinct, what could cause 64 bit arch not to boot when 32 bit arch boots fine on a non-UEFI system that supports 64 bit, when all other variables are constant?
My first response seeing this post would be to immediately assume the noob (me) posting this doesn't know the difference between a 32 and 64 bit system. However, "ubuntu-14.04.1-desktop-amd64.iso" (latest 64 bit ubuntu iso) boots from live USB and installs without error. It also came preinstalled with Windows 7 (64 bit), so I'm relatively sure it supports x86_64.
I wrote "archlinux-2014.08.01-dual.iso" (MD5 verified) to my USB. Selecting i686 boots fine. Selecting x86_64 restarts my system, eventually sending me back to the arch live menu after it posts.
Upon recommendation by a WonderWoofy on reddit, I tried to install arch x86_64 by bootstrapping and chrooting from the 64 bit ubuntu live usb. I ended up with same problem, where attempting to load arch reboots my system immediately.
Right now, I'm assuming it's the same issue booting from the live usb (arch iso) and from the arch installation on my hard drive, since they seem identical to me. I haven't tried recreating the install for i686 to see if it works (mainly because it's late -- if it'll help I'll do it upon suggestion).
Here's the only text that shows once I attempt to boot into arch. This is from the hard drive and using syslinux (which is pointed at my root partition on sda -- I don't have a boot partition).
Loading ../vmlinuz-linux... ok
Loading ../initramfs-linux.img...ok
Probing EDD (edd=off to disable)... ok
Which doesn't look like it's messing up anywhere...
And of course I'm a noob so go easy on me x)
UPDATE: I found this thread but I'm not seeing his error message, so I'm not sure what to do.

There was, and maybe still is, a Skype dev floating around here somewhere. He said that they are working on it. But, if memory serves me well, I think that the number of people working on the Linux client may amount to only one!

Arch X86_64 - Logmein Plugin

Hi
Hope you can help me with this one:

But when i try to remote to a computer...i can't....it stuck on connect network...and then error message as disconnected....
Any ideas or someone in the same situation.

[Bounty] Free Macbook Pro to get Arch Linux running on Amazon's EC2

First, the details:
I will purchase a lowest–end Macbook Pro 13″ ($US 1,200 on Apple's store, new) for the first person to deliver to me a working set of step–by–step instructions for installing the latest Arch Linux on top of Amazon's EC2 platform.
Caveats & Rules:
- I don't care how long it takes you—there's a good chance I'm doing something absolutely stupid in my noobishness that's causing the problems I've been experiencing; if it takes you half an hour to make a working AMI, and produce instructions to do such… you just won yourself a Macbook Pro for half an hour's work. Booyah!
- Again, I say, I don't care how long it takes you—if you don't produce a working set of instructions, there will be no payout, even if you spend 200 hours trying (as I already have!). It's a bounty, not a work contract d-:
- You must provide me with instructions that work for me (as I don't intend to use your AMI, but rather modify the steps that worked for you a bit at a time until I arrive at an AMI configured exactly as I want it). If you arrive at a working AMI, and can reproduce your steps successfully locally, but they can't be made to work for me, I may be able to go about procuring alternative hardware for myself on which to preform the steps, or taking other measures to reproduce your environment; but the bottom line is I will not shell out until I can, personally, produce a working AMI running Arch Linux.
- The instructions are considered to be "working" when I can successfully SSH into the root account on an instance instantiated from an AMI created by following the instructions using the key generated by EC2.
- Your instructions must work both for x86_32 and x86_64 instance types; however, this shouldn't be too much of a problem, as (barring any weirdness) anything that works on x86_32 should be easily made to work on x86_64.
- Instructions that involve instantiating an intermediate bundling host (say, a CentOS or Fedora Core instance) and then installing Arch to a loopback filesystem using a statically–built pacman are much preferred to instructions that involve me having to install and package Arch locally and then ship it up to S3, because my upstream is unimaginably slow and I eventually will need to create something between eight and twenty different AMIs (see below). But anything that works will be accepted.
- If you don't want a Macbook Pro, alternative payment methods may be arranged, though you need to contact me before you start and arrange these, as there's only so much I can do.
- If you are in any way confused or unsure of what I'm offering here, please contact me before you start (see below for contact info)
Backstory:
I set up the first AMI for Arch Linux on Amazon, but unfortunately, I did some really stupid things (hey, I was completely new to Linux at the time, gimmie a break!). The root filesystem was limited to 1GB, there was a whole bunch of software that really was completely unnecessary (WiFi drivers? on a virtualized server? seriously?), there were no kernel modules provided… and so on.
So, after running all my stuff on instances of that for a while, I finally got fed up and found the time to start setting up a newer, cleaner AMI. Unfortunately, I made the mistake of deleting my old AMI before starting work on the first. Now I find myself completely unable to create an AMI that will work whatsoever, and I cannot for the life of me figure out why.
I've already invested 200 or so hours of my personal time since deleting my original, broken AMI; I'm very fed up and in badly need of working instances. I tried every method I could think of; running the Arch installer from a LiveCD locally and then bundling the running (and thus proved working) Arch install and shipping it off to S3; installing Arch on a loopback filesystem locally, cloning it to a local partition, booting to it to ensure it works, and shipping it off to S3; installing Arch on a loopback filesystem on a remote bundling host running CentOS or whatever and then shipping it off to S3… I've tried installing nothing but the essentials, I've tried installing everything the installer offers… I've tried to do my best to remember the exact steps I took the first time around, years ago, and reproduce them exactly… nothing has worked.
If I take EC2 out of the equation, and install the images I've prepared locally, they work. If I take Arch out of the equation, and install, say, CentOS instead, and then ship it off to EC2, it works. The only time I have problems is when I attempt to install Arch Linux specifically on EC2 specifically; the exact use–case I need.
I've run into a lot of problems along the way, and fixed them as I go, but I universally end up with an AMI that, once instantiated, does not successfully boot. Worse yet, I get absolutely no output from the console (provided by the ec2-get-console command–line tool) to help me debug the problem. I can't give you any more specifics beyond this to help you, because I don't want to insinuate some idea that will cause you to make some little stupid mistake that I also made, thus dooming the project.
Contact:
For more info of any sort, please hit me up on Google Talk or Jabber (… or any other XMPP–federated chat service, or AIM, or ICQ, or MSN, or whatever you like, they all use the same address anyway) at the following address:

Edit: I should point out that it would be good form to post here if you're going to make a stab at it, so interested parties know how many people are already making attempts.

Public AMIs aren't what I need, because I need to mass–produce quite a few AMIs with different custom configurations for different purposes; so I have to be able to start from scratch and arrive at a working AMI *myself*.
As for the script, I'm sitting down to play with it now; it looks just about exactly like what I've been doing so far. Maybe there's some small thing he did differently that will make it work. Here's hoping it works for me; that'll be a real load off my chest.

Help!!! Sansung laptop 300e4x-u09,Arch x86_64 GUI slow

Hi all:
I just bought a new laptop , Sansung 300e4x-u09 ,which has intel i3-2328 cpu , NVIDIA GeForce GT 620M graphic card , and 500GB harddisk , 4 GB RAM ( I added 2 GB );
And I installed Archliux x86_64 using the 2012.10.06 install media following "The beginner's guide"
It boots to login manage (I tested slim and kdm) for a long time , and start the kde very slowly even xfce4 also slowly, after installing the intel graphic driver follow wiki , then reboot and startx ,one cpu core used 100% , and the DE(xfce4) starts also slowly , and I can not logout or reboot computer in xfce ( I could do these before intall intel graphic driver ) and the harddisk's led blinks when start DE.
I tested Compiz-fusion , but fails...
I got errors when run "Xorg -configure" as root , it says Server terminated with error (2) , how does this happen .... if you know ,please tell me how to config Xorg correctly .
My harddisk partion (GPT partition table) :
sda1 nofs 2MB for_grub2_core_img
sda2 xfs 50GB /
sda3 xfs 50GB /home
sda4 xfs 115GB
sda5 xfs 100GB
sda6 xfs 100GB
sda7 reiserfs 16GB /var
I used parted live CD to make partitions using default settings.
Now I want to reinstall Arch , I don't know whether the GPT or the 64 bit or the XFS FS affects the GUI speed,I intalled Arch 32bit half year ago ,using MBR partition table on a old PC,it ran fast ,I do not know why this happened on new laptop.
any suggestion on / partition FS , EXT4 or XFS or others ?
how do you get deal with Nvidia card and integrated intel graphic card , just shutdown the Nvidia card ?
any suggestion on optimize arch ?
Thanks

Why such crazy partion layout?
I installed Arch on my laptop(Leno Thinkpad Edge E530) some days ago my partion layut was the folling:
Drive 1 500GB:
Size Mountpoint Type Comment
1 MB none none for disk alligment
100 MB /boot ext2
30GB / ext4
430GB /home
I think they reason was your partion layout and maybe you don't installed the intel drivers.

I have a naive memory question for some knowledgeable folks. My machine has 2x2 Gb sticks which should total to 4096. When I do a free -m under Arch, it's only showing 3950. Is the remaining 146 reserved or..?
$ free -m
total used free shared buffers cached
Mem: 3950 422 3528 0 28 157
-/+ buffers/cache: 236 3714
Swap: 2000 0 2000

Thats a really good question and the result you get is normal as far as I know.
Part of it (a small part I believe) is used by the kernel, the rest of it, and this is where things are not so clear, is reserved as an agp apperture.
As far as I could tell (I have stumbled uppon that too) the problem seems to be that some bioses don't setup everything as they should.
The thing is that some devices can only handle 32bit addresses so their address is somewhere until the 4GB mark, because the bios doesn't setup the memory remapping correctly (sometimes the user has no way set anything related to memory remapping, this seems to be the case with some desktop boards and most notebooks/laptops). This memory remapping "problem" was anticipated and there are ways to properly handle that.
For some reason unknown to me (and most people that have stumbled upon this) many bioses don't setup (or allow the setup) of proper remapping. To add to the problem the kernel seems to reserve 128MB of agp aperture by default even if you don't have an agp card, this reserved address space falls in the first 4GB of addressing space therefore stealing you some memory.
I have tried to regain those MB, I have tried to recompile the kernel with a different config and I've tried several kernel boot parameters and the only thing I could regain was 64MB if I recall correctly. I can't find now what I have added to regain those 64MB, I didn't keep that option in the kernel line, 64MB were not worth the possibility of having problems later on.
I know its a pain to have that voice in the back of your head telling you that there is some memory that is being wasted, specially if you have tried a 32bit kernel with support for 64GB of address space and got 4050 MB of usable memory, but just leave it as it is, it's not worth the time and the trouble.

Console font size in console mode Arch x86_64

hi
i do fresh install Archlinux 2013 x86_64. so i see some change btwin that and 2011, any way , everythings work OK, fast (KDE) but sometime i need work in console mode (ctrl+alt+f1) but i cant change resolution of console font, because now is settingsome basic and so big. i have nvidia card and drivers. i try read ths https://wiki.archlinux.org/index.php/Uvesafb but i cant find some solutions how setting everything with grub2 etc. in my old laptop i have arch 2011 and grub1 but everything work OK include console font, that was much better to setting, in that arch i cant find any working solution, so please help me if somebody know about this.

[ 15.458823] NVRM: Your system is not currently configured to drive a VGA console
[ 15.458830] NVRM: on the primary VGA device. The NVIDIA Linux graphics driver
[ 15.458834] NVRM: requires the use of a text-mode VGA console. Use of other console
[ 15.458838] NVRM: drivers including, but not limited to, vesafb, may result in

I suspect that it's still the case. You may even have this message in your own dmesg.
Switch console to VGA mode and use xterm instead.
This has nothing to do with resolution setting in a framebuffer, which is what the title of the thread suggests.
I'm pretty sure it does - it looks like the console is being switched to VGA text mode; nvidia has no reason to touch fonts.

Bumblebee is not work on Arch x86_64

when i install bumblebee on arch_i686 ,it works,

# pacman -S lib32-virtualgl bumblebee bbswitch
# usermod -a -G bumblebee eveblue
# systemctl enable bumblebeed.service
# reboot

Hi,
if you only followed the steps you quoted above, I'm more suprised by your suggestion that your nvidia is off on boot when you are on arch_i368.
'Default behaviour of bbswitch is to leave card power state unchanged', as is explained here:
https://wiki.archlinux.org/index.php/Bu … g_bbswitch
Did you configure bbswitch according to the steps outlined there ?
ciao,
J.
(sorry, misread the docs i realize now, and can't delete this post..:()
I use bumblebee and bbswitch and I did configure it in a bbswitch.conf as outlined in the link above, even when now I see it says that is not necessary when using bumblebee. Did you try that ?
thx,nourathar
but the bumblebee install will turn the Nvidia off,and I had read the wiki before and try myself to configure the bumblebee ,but it doesn't work.
I think ,are there some lib32* not install.
And sorry for my poor english.
