REFInd, 64bit Arch, and a 32bit EFI (MacBook 2,1 2007)

I installed rEFInd on a 32bit EFI MacBook, and after copying the filesystem drivers into /efi/refind/drivers, was able to boot into an UEFI stripped install cd. I ran through the install, taking notes from the MacBook wiki entry
I am under the impression that rEFInd should do magic and find linux inside /boot (as suggested here) but the automatically generated "Legacy" OS entry fails: "Operating system missing." Perhaps because the kernel EFI stub is 64bit while the EFI is 32?
My failing manual menuentry errors with "Error: Not Found While Loading vmllinuz-linux." I suspect this is because I do not have the partition labeled correctly (see diskutil and gptfdisk outputs) or am expecting rEFInd to be able to read into places it can not. But am mostly totally clueless.
I also did some configuration before realizing /efi/ on the mac partition is different than the ESP (EFI system partition) and am still unclear how the two are related.
Any one have success with a similar setup?

Thanks for the link! It's unclear to me what happens when a bootloader is installed to the MBR in the hybrid partition table. Mac will go into BIOS mode and use that bootloader? EFI will still take precidence and rEFInd will give an option to boot to the MBR (is that what happens now, and the reason for the no OS found error?)
I thought going to EFI-installed grub or syslinux through rEFInd might work. I'm able to use the 64bit kernel on the install CD.
Unfortunately, --target=i386-efi as suggested by the grub wiki doesn't work. Expected files are missing

is there an alternative grub package?
[I'll be back with an edit after backing up the mbr and trying syslinux ]

Arch and MacBook Pro 8,3 2011

Hello all! I have a MacBook Pro 8,3 late 2011 model. It has an Intel HD Graphics 3000 (i915 driver) and a AMD Radeon HD 6750M (radeon driver). I have been successful in setting up a partition for Arch and booting via EFI, but I am hitting a wall with the graphics portion of the configuration. If I edit the boot entry (pressing e when Grub comes up) and add the nomodeset kernel parameter the screen stays responsive and I am able to log into the system. Without adding that parameter, the screen stops updating. I have read up on the mux that controls the two graphics chips and it sounds like the the Radeon takes over, but is not pointing to the screen.
I am not too concerned about the Radeon working at all. I primarily want to use the Intel chip and would only want to use the Radeon if could get something like vgaswitcheroo to work. I followed the documentation at https://wiki.archlinux.org/index.php/Ma … 8,3_(2011) and added this to my 10_linux Grub entry
outb 0x728 1
outb 0x710 2
outb 0x740 2
outb 0x750 0
but I’m still not able to get the system to boot without manually adding the nomodeset kernel parameter each time.
Any suggestions?

Anyone here with some insight?
Just to give a little more information on the graphics problem. I can boot fine with KMS enabled for i915 and I see all the tty boot information fine and can use the tty consoles fine, but when I startx with the intel driver it looks like it is going to start fine for a second and then tty7 is just blank/black. I can go back to other tty's and when I look at /var/log/Xorg.0.log there are no errors that I can see. From the log it appears that the driver loaded fine but tty7 is just blank/black.

32bit java on 64bit arch

Hi,
I have 64bit archlinux. I have installed eclipse and openjdk from repository so both are 64bit version. But I need 32bit version of java for actual job. So i downloaded it from oracle's web. Now I have two java on my arch (./usr/lib/jvm/java-6-openjdk - 64bit and /opt/java/jdk1.6.0_34/ - 32bit). When I changed $JAVA_HOME to 32bit version, eclipse didnt works. So I change $JAVA_HOME back to 64bit.
And my question. If I add new (32bit) java virtual machine to eclipse and select it for use, will be this 32bit version used for programing?
And what about maven? We use maven for build project. Can I set it to use 32bit java?
Thanks

you can create a script that wrapps maven with 32 bit java
Call it sth like mvn32 , put this to your $HOME/bin direcotry and insert following:
#!/bin/sh
export JAVACMD=/path/to/java-32/bin/java
#or
#export JAVA_HOME=/path/to/java-32/
mvn $*
Then you call mvn with mvn32 clean install for example.
When name this scipt mvn and ensure that $HOME/bin is the first entry in your $PATH variable this scipt will be excuted as first when you call mvn
An other alternative is edit /opt/maven/bin/mvn
and adjust the JAVA_HOME Variable to your 32 bit jdk-

64bit distro and browser but need 32bit plugin?

Ok so i have an issue where i run 64bit Arch with 64bit chromium.
I've also enabled multilib and installed a Swedish Identity Security Software that requires a 32bit browser with Flash/Java support.. and I'm not quite sure how to go about this.
My first thought was to install pacman -U firefox... with a downloaded 32bit version and hope for some magic but that didn't work so well.
So any ideas on how to solve this?
I need either for Chromium to run as if it was a 32bit environment to fool the "plugin" (that being Java loading the 3 party software called BankID) or an actual 32bit browser (pref Firefox or something other than Chromium to not mix them up)

Pierre wrote:
Maybbe nspluginwrapepr still works. You could also always use a container/chroot or vm.
But then, a proprietary "security" plugin that requires java and flash? I don't think you really want to install or even use this.
How would i go about creating a temporary chroot? do i need to know the specific location of the plugin for that to work or just do a /usr/lib32 something?
Hehe, i'm well aware that "security" and "flash/java" doesn't ring to well, but it's the only option in Sweden to authenticate as "me" when doing banking and social security tasks i'm afraid.
Doing taxes atm and just moved and both require "BankID" :/
a VM is a sure thing solution, as a last resort i'll go down that road and install either some dummy Win7 or Arch-32bit :)

[SOLVED]Compiling 32bit C programs on a 64bit arch

Hi guys, for the first time I decided to use 64bit arch on my machine and so far no complains (I don't think there will ever be). I'm a student of computer engineering and I use C to code some projects but I haven't found a way to compile 32bit programs on my 64bit arch. Everybody says "just add -m32 flag to the compile step" but I think this is not all I have to do (it doesn't work if I just do that).
To prove it I have created a simple "hello world" in C:
#include <stdio.h>
int main(){
printf("Hello, World");
return 0;
When I try to compile it, I just run
gcc -m32 hello.c -o hello
But all I get is
In file included from /usr/include/features.h:399:0,
from /usr/include/stdio.h:27,
from test.c:1:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
compile finish
Needless to say it doesn't create the hello executable. Is there some packages I have to install in order to have this happen?

Well, you could see that something "-32" is missing so you are searching for 32 bit stuff that is not installed.
There's a tool called pkgfile which searches in the repository database for a file name and tells you which package it is in.
In this case, stubs-32.h
~ % pkgfile stubs-32.h
multilib/lib32-glibc
Maybe another helpful article: https://wiki.archlinux.org/index.php/Ar … ib_Project

Hey, I'm doing some cross browser testing and i want to know Is there any difference between the behavior of Firefox in an operating system 64bit & operating system with 32bit. (like windows7/windows vista...)

Hi Kossa,
You can also check if the issue occurs in
Clean Boot. If the issue disappears in the Clean Boot environment, you can continue to narrow down which entry is causing the issue.
Besides, uninstall it and re-download
a fresh copy of FireFox to check the result. If the issue still exists, create a new user account to see if it occurs.
If the issue persists, you can contact Mozilla Support directly and use Internet Explorer (IE) during the time.

My MACBOOK Pro turned out to be Snow Leopard, and later upgraded to LION. And update the EFI, I would like to replace the Snow Leopard, EFI can not boot, how do? How to use the Snow Leopard install disk to reduce EFI?

My MACBOOK Pro turned out to be Snow Leopard, and later upgraded toLION. And update the EFI, I would like to replace the Snow Leopard, EFIcan not boot, how do? How to use the Snow Leopard install disk to reduce EFI?

Do you mean some of your software does not work in Lion? Do you want to return to using Snow Leopard? If so, then do this:
Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

32bit and 64bit Windows and Lookout

I have two versions of Lookout - 6.0 and 6.6. I am trying to install them on Windows 7/64bit version and find that when I install them, they do not start up at all. I click on the icon and nothing happens. Is this because these versions of Lookout can run only on 32bit version of Windows 7? Or is this another problem entirely?

Hi, I am having problems running Lookout V6.7 on a Windows 64bit machine.
The problem is actually once installed, my laptop will no longer boot up properly. I have a Panasonic Toughbook, CF-53 with a 512 SSD, 16GB RAM. The laptop will boot up and then sits at the "Please Wait" bit before you get to CTL - ALT - Delete to login.
I think there is an NI service that is not starting up properly. Once Lookout and all NI software was uninstalled, it seemed to start ok.
Funny thing is, once booted up (using Windows Safe Mode without Networking), I could generally restart the laptop and it would be ok, but if it was shutdown and then booted up later it wouldn't reboot.
Any one have any ideas on this?
Any help would be greatly appreciated.
Thanks!

QT 32bit on 64bit arch

I want to develope a QT based application for android using a 64bit archlinux. I also want to test it on 64bit archlinux. The problem is, that i have to use a library which i have for android and for 32bit linux only. So i need a 32bit QT for 64bit archlinux to build and test the application on my pc.
I have installed QT for android from aur, but i can't find it for 32bit on 64bit archlinux.
(Because i want to develope an android application i need a QT version >=5.1)
I tried to compile Qt from source with this configuration
./configure -platform linux-g++-64 -xplatform linux-g++-32
But it doesn't work. I also tried to export this before compiling:
CFLAGS = -m32
CXXFLAGS = -m32
LFLAGS = -m32
But it doesn't helped. Qtcreator says, that i have a 32bit compiler(gcc) so that should not be the problem.
I tried a chroot as well like this https://wiki.archlinux.org/index.php/In … _in_Arch64 , but when i try to install qt i get the error that it is for the wrong Architekture. I can't install some packages. Some other are working.
I just started learning c++ and QT(but i have experience with c and i'm a java developer). So is there a way to get this working? Or do i have to install a 32bit archlinux for this?
Thanks for reply

I had a problem compiling my qt programs until I found this http://www.spinics.net/lists/gcchelp/msg36767.html which basically tells you to install gcc-multilib. If you don't have gcc-multilib installed it probably just ignores the -m32 flag.

Screen flicker and trackpad issues on macbook pro 8 2

Hi I have a macbook pro (8,2) 15 inch with a high rez anti glare display. The display stared to flicker after living my computer open in arch for about 30 min. I tried rebooting and it even started happening in the boot screen and in mac os x. The last thing I did before it happened was setup pommed in arch and leve my computer open.
Also this has sort of been asked but my question is a little different. I am trying to set up my multitouch trackpad. I installed mtrack from the aur but changing the settings does nothing. What I want to accomplish is this. 1) I want to right click by clicking (not tapping) with one finger in the button right corner of my trackpad. 2) I need to disable tap to click!!!! 3) I want to be able to click the trackpad with my thump and use my index finger to drag instead of only my thumb. for example I want to click on a window border with my thumb and move it around with my index finger while holding down my thumb.
Any help would be greatly appreciated!

Glad you figured it out. Sorry to see no one else chimed in.
I have arch on a macbook as well. I have never seen a need for the many elaborate packages which claim to make these things work. If they're working then stick with it - but if you need another option, I've had great luck with simply properly configuring synaptics:

[Solved] Boot process hangs for installed Arch and installation usb

Hi. I've been using Arch Linux for around 6 months now and I'm in love with it. It is now my primary OS. However, I might have done something or performed some update, and I can no longer boot into Arch. The boot process hangs right before it should show the login screen (I'm using Gnome 3.6 with GDM). I see the following messages on the screen:
Loading Linux core repo kernel ...
Loading initial ramdisk ...
/dev/sda3: recovering journal
/dev/sda3: clean, 330610/1749664 files, 5585671/6996827 blocks
And then it hangs right there. I have to hard-reboot after this.
I then tried to boot using the Arch Linux Installation USB (archlinux-2012.12.01-dual.img), which also hangs at a particular point, before it should show me the prompt. I took a picture of the screen where it hangs: Screen Capture. This is an issue with just my laptop, because the USB boots just fine on another laptop I tried.
I also have Windows 7 and Ubuntu 12.10 installed on my system, and I'm able to boot into both of them.
I have 2 hard drives: /dev/sda is a 120GB SSD, and /dev/sdb is a 500GB hard disk. My partitions are as follows:
sda1 - Windows 7 100MB System Reserved Partition (boot flag enabled)
sda2 - Windows 7 OS
sda3 - ArchLinux (boot flag enabled)
sdb1 - Ubuntu 12.10 (boot flag enabled)
sdb2 - Just data
I ran bootinfoscript and below is the output:

Ok.. So my Arch Linux randomly decided to work. I'm sure I didn't do anything between my last "not working" state and my current "working" state. Below are a few things I tried:
I thought of trying an earlier build of ArchLinux, and downloaded archlinux-2012.11.01-dual.iso and made a bootable USB out of it. It still hung.
I was getting error messages during Arch boot that the last access time for the disks was at a future date. I found out that Ubuntu was using localtime instead of UTC and screwing up my hardware clock. I fixed it, and thought maybe the time issues were causing the boot problem. But fixing time didn't solve my problem.
I chrooted into Arch from my Ubuntu install, ran 'sudo pacman -Syyu' and updated my Arch install.
I thought maybe GDM isn't starting up. I re-enabled the service using 'systemctl enable gdm.service'.
I removed OpenNTPd and installed NTPd. Enabled the daemon using 'systemctl enable ntpd'
None of the above solved the problem, and rebooting to Arch still hung the system. So I stopped fiddling with it yesterday. Today, as usual, I just tried logging into Arch.. And it just worked out of the blue. The solution to me is as mysterious as the problem.
I told this to my friend who introduced me to Arch, and this is what he said:
Damn it computers, you were supposed to be deterministic!

Dreaded Gray screen with Folder and Question Mark (EFI Boot poofs away)

Hey--
I've had trouble with my Imac that I purchasd in 2005 for a year and a half or so. I had a gray screen about a year and a half ago, went on vacation for a week, came back and it booted just fine. Another time it went down, I did a safe boot and it came back. I've tried Command-Option P+R before with some success. I had a boot camp partitioned windows xp drive on there also (I don't know if this matters, but wanted to mention that). I've also tried putting the installation disk in there with no luck (thinking it would find the software on it)
I put it away because I moved and dragged it out of storage to see if a miracle might have occured since the last time I tried 5 months ago. Well, same thing--gray screen with a flashing folder with question mark. I read in the discussions to hold the option key down to select a book device. I tried this and got an EFI Boot icon with a mouse pointer, but when I go to select it it "poofs" away (literally, the icon POOFS away) before I can select it with the mouse pointer icon.
Has anyone seen anything like this or have any suggestions? I guess I'm at my wits end and am ready to haul it down to the Apple store to get the prognosis (I'm sure it will not be good--probably shot hard drive or something). I'm hoping this can be salvaged without much cost.
Thanks so much for any advice or input you might have.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.
If yours is an Intel model, then I recommend getting Snow Leopard to upgrade OS X, but I would recommend first erasing the drive before installing Snow Leopard.
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
     Are my applications compatible?
         See App Compatibility Table - RoaringApps.
