installing on x86_64

installing on x86_64

[Constantine Kousoulos]

Hello,

I fetched the latest sources from cvs and tried to install grub2. 
I followed the guide at the wiki http://grub.enbug.org/TestingOnX86.

'configure --prefix=/boot/grub2': works ok.
'make': ok
'sudo make install': complaints about missing file 
utils/grub.d/README.  easy to overcome.
'sudo grub-install --grub-setup=/boot/grub/grub.cfg /dev/hda': 
there is no arg like '--grub-setup'. i used instead 'grub-install 
--root-directory=/boot/grub2/ /dev/hda'
'sudo grub-setup  --directory=/boot/grub 
--device-map=/boot/grub/device.map /dev/hda':
i get this error
'grub-setup: error: cannot stat /boot/grub2/boot.img'
so i copy boot.img to /boot/grub2. Then i get the same complaint 
about core.img which does not exist.

Any advice is welcome.

Thanks,
Constantine

Are you sure you did this on an x86-64 install. Current CVS still
suffers from the not being able to properly compile on x86-64 systems.
I am looking into it again now, but I think you may be mistaken in how
you are using it? What distro & gcc version are you using ?

It compiles fine here... are you sure your compiler can generate
32-bit code?

Really..exactly waht distro and gcc version are you using. There is
still lack for _start with compiling 32-bit binaries using gcc x86-64.
I'm currently been testing on Fedora Core 7 beta and I see the problem
consistently (though I do need to update it some). Others have
reported the problem in the past also. What I do need to know is how
you are successfully compiling it . Is your gcc version less then 4.x
?

I'm using Debian, both gcc 4.1 and 4.2 works. Missing _start means
that your compiler can't generate 32-bit programs. Test this first by
compiling a simple test program (e.g. "int main (){return 0;}") using
-m32. That probably doesn't result in a working executable either.

Ok.. moving over to ubuntu (fiesty) it appears things do work (once
you have all the 32bit shared libs installed). Wow... I was basically
spinning my wheels for a bit there.

I don't appear to have a problem with the binaries though. I will show
what I did:

1) ./configure --program-transform-name="s/grub/grub2/" --prefix=/usr
(this will rename everything grub2 and not conflict with the current
grub install)

2) make && make install

3) grub2-install /dev/sda

I did not reboot. But It ran grub2-install ran fine (and of course all
the programs being tried, which the grub-install script uses) and it
ran and when through the process just fine. I assume based on this the
grub did install just fine (as it would have errored otherwise).

Thank you for your reply. After so much time, i had totally given 
up on grub2.

I have a debian-amd64/unstable system running on a turion64 
processor with gcc 4.1.3, autoconf 2.61 and automake 1.10.

I will try again to install grub2 using your instructions and 
report back.

Re: installing on x86_64

Jerone, thanks to your instructions grub2 was installed 
automagically!!

The only thing that wasn't set up automatically was grub.cfg but 
this is a minor issue to resolve.

Are there any objections to replace the wiki's inaccurate 
instructions at the section "TestingOnX86/Installing GRUB 2 into a 
real system" with Jerone's instructions? I assume he is too busy 
to do it himself so i volunteer. If i don't get any positive 
feedback i won't do it because i'm no grub2 expert and maybe you 
want someone more experienced to do it.

Thanks,
Constantine

You can use update-grub for that.
