Comments: If you need something compiled 64-bit, this is the way.
      Either run toolchain64-shell, or start it from the menu;
      this sets up some variables so that you can build easier.
-
      Example:
      ./configure --host=x86_64-unknown-linux-gnu
-
      Note that this is a cross-compiler, and so there might
      be some more difficulties compared to native compiling.

So, looking to the future, here's a 64-bit cross-toolchain. I have tested it on busybox, wget, and the linux kernel.

Note that we accept no 64-bit extensions for the time being; nor can you run such without suitable hardware and kernel. This is for testing, and will be used to compile the 64-bit kernel for 3.x.

PS: Might take a while to upload, these have some mighty sources.

Post by: Juanito on February 11, 2010, 03:09:15 AM: based on testing with a different distro on a different architecture, the same app will run 10-15% slower...

That's not at all to knock it, you get access to ram > ~3.5GB as well.

Post by: gutmensch on February 11, 2010, 03:33:10 AM: hehe yeah I know about most of the difficulties... even that PAE might work without doing anything at all ;)

but: 64 bit arch is needed sooner or later and I don't see any sense in still sticking with 32 bit, when it's possible to push the arch for the next 20 or 30 years and (despite of atom, netbook, etc.) this will be x64. I also think that most of the transition problems are relicts to old architecture features and not because x64 is slower in general ;)

so call me a hero.. I will give 15% system power away in order to bring x64 to the people, yaayy :D

Post by: coreplayer2 on July 05, 2012, 04:03:30 PM: Great tool thanks, just in time for a build.

Am getting a "Upgrade your gcc" error " -mcmodel=large not supported

?? needs an update already?? Please

Wait.. maybe I shouldn't have compiletc loaded at the same time..?

Are you sure this is the subforum you meant to post this in?

Post by: coreplayer2 on July 06, 2012, 12:00:48 AM: Sure it is.. But I was compiling a 64bit application whilst other tools were loaded :( so that was the error I'd got, anyhow I figured out on my own. My bad, but it's a gas right??

-mcmodel=large
Generate code for the large model: This model makes no assumptions
about addresses and sizes of sections. Currently GCC does not
implement this model.

This mail: http://gcc.gnu.org/ml/gcc/2010-10/msg00321.html
says that mcmodel=large changes the ABI, and so you need to compile _everything_ with it. That seems quite unnecessary, what code wants that option?
