digitalmars.D - [OT] Ubuntu 12.10 guest in VirtualBox completely broken

I just wanted you all to know that running Ubuntu 12.10 as a guest in

12.10 and it's so slow it's not usable. This is a known issue:

https://www.virtualbox.org/ticket/11107

That issue contains a pre-release of VirtualBox, I tried that on Mac OS 
X and it broken the Ubuntu guest even more. No title bar on the windows 
or any window frame actually.

What a coincidence, I just installed VirtualBox and was looking for 
advice on what distro of linux to install...

All I want to be able to do with my VM is be able to build GDC for my 
RasPi (via all the hoops that are necessary to get cross compilation 
working), not bothered about any GUI stuff or bells/whistles, 
suggestions for a good distro to go with are welcome!

Ubuntu 12.04 was working perfectly fine for me. Another alternative 
could be Linux Mint. I haven't used it myself but I heard it's basically 
Ubuntu with less bells and whistles, i.e they're not using the Unity GUI.

Ubuntu 12.10/gnome classic works well enough; just turn off compiz. I 
tried mint and ran into trouble while compiling llvm. make gobbled 
memory for a while, and then the desktop restarted itself (I guess?). 
All my windows: gone.

I don't know if I can do that when basically the only thing that works 
are the desktop icons. Neither the top or left bar is displayed. I 
should perhaps go back to an older version of VritualBox.

I manage to turn of compiz but I don't know if I made some bad choices 
in the process because now I only have the desktop. No left or top bar.

Ouch. Looks like what I should have said is gnome classic (no effects), 
and I guess compizconfig didn't actually turn anything off. Also, I'm 
working from a clean install, so that might account for behavior 
difference.

It still sucks, though. Found myself wishing I had installed server instead.

I start to think I have to reinstall.

I was using this virtual machine for testing DWT Linux as well, so I 
kind of need a GUI. I was hoping I could use the same machine for 
building Linux binaries as testing DWT.

I use Arch Linux for this kind of stuff, and just ssh into my VMs 
instead of running X on them. I especially like Arch for this 
because it doesn't come with loads of bloat (for this setting) 
installed by default, yet is comfortable to use – at least if 
you are somewhat familiar with Linux already.

You don't necessarily need a cross compiler to do the job. Set-up a
raspbian chroot instead!

There's some rough instructions here.

http://superpiadventures.wordpress.com/2012/07/16/development-environment/


You are also able to debug programs through qemu, though there's a
hurdle you have to jump through.

interesting...

but a lot of these instructions assume a lot more linux expertise than I 
have to hand, even the ones that claim to cover every step miss things.

That's one of the reasons that I made my RasPi available to all (as long 
as they ask for an account) ^^

The comments on the first article say that using qemu is as slow as 
compiling on the RasPi, and recommend using the cross-compiler instead.

I followed the instructs anyway, and all seemed to go well, but they 
just stop without detailing how to actually compile anything, or 
explaining what has been done ><

Your milage may vary depending on what hardware you have.   Personally
I find it 3-4 times quicker to build (considering it takes about 24+
hours to built gdc on a RasPi device).

What's been done is a chroot system has been set-up with ARM binaries,
instead of i386 or x86_64.  qemu-debootstrap installs an executable
qemu-arm-static inside this chroot, so when you try to run any ARM
binaries, qemu kicks in and acts as an emulator.

To compile, simply following the same instructions as per the gdc
wiki.   apt-get install all build deps, retrieve source, ./configure
and make.  :-)

6–8 hours to build?! I sure love building LDC on my ODROID-X. ;)

Ya, but how many lines of code is LDC vs GDC+GCC. :-)

o.O

you are still assuming I have way more pre-existing linux

explaining in tiny baby steps...

I followed the instructions, pretty sure I will have messed up 
somewhere, read some more of the comments on the original qemu 
instructions and someone points out that if reports to be emulating the 
wrong arm processor, and no one has posted to say they have had any 
success, never a good sign ><

Don't think that would be the case for you.  It works just fine, just
make sure you are using the correct configure --target flag.

On my third time running through the instructions I felt like I was on 
the right track until I got to the part about running

./setup-gcc.sh $HOME/gcc-4.7-4.7.1/src

to "add gdc to gcc sources"

but this script is not in the branch that I got from git!

There is a

./update-gcc.sh

which I have tried to run, but I only got the help message or an error 
depending on if I add "--setup" or not ><

should setup-gcc be present? if not, what is the correct way to call 
update-gcc?
