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 
knowledge/experience than I actually do, I really do need this stuff 
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.

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.

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?

OK, ibuclaw helped me over that hurdle over irc, it is now building (I 
think) ^^

My next stupid question, is once its compiled on the qemu chroot, how do 
I get it onto the RasPi?

Someone in IRC mentioned IPoAC.  I think this is the way to go. ;-)
