Toolchain update for new binutils

Postby kmihelich » Sat Dec 10, 2011 11:58 pm

Toolchains have been updated for both v5 and v7h targets for binutils 2.22. The crosstool-ng configurations have also been updated appropriately, so anyone using a distcc cross-compilation setup should grab the new config and rebuild.

I had a good go at this, otherwise my new i7 will be idle
Had to modify config file thus (it didn't like custom)
Code: Select all
#
# Operating System
#

CT_KERNEL="linux"
CT_KERNEL_VERSION="3.1"
# CT_KERNEL_bare_metal is not set
CT_KERNEL_linux=y
CT_KERNEL_bare_metal_AVAILABLE=y
CT_KERNEL_linux_AVAILABLE=y
CT_KERNEL_V_3_1=y
# CT_KERNEL_V_3_0_4 is not set
# CT_KERNEL_V_3_0_3 is not set

CT_KERNEL_mingw32_AVAILABLE=y

Next, distcc has altered, you define how many threads each can handle, new guide is here

Can't get this working (yet), logs on i7 look like this

Told ya kmihelich, I told ya they wouldn't like -custom. :P What I did was just download linux-3.1.tar.bz2 into ~/cross/src and rename it to be linux-custom.tar.bz2...

That didn't work for me, it still unpacks to Linux-3.1 and it wants Linux-custom directory.
What concerns me is distcc works but doesn't work. Plus there is a new directory /etc/distcc

The only change from distcc 3.1-6 to 3.1-6.1 was adding a patch for user adjustable IO timeout, and the upgrade didn't effect my devices.

I'll take a closer look at the ct-ng configs and see what is happening. Those configs were uploaded directly following my successful rebuilds.

It looks like you were using one of the newer versions of ct-ng? I just rebuilt using 1.13.0 and the config works as expected. Setting the kernel version to custom, combined with the flag below and location specifies to ct-ng to use that specific tarball as the kernel source. The xtools-dotconfig-v5/7 files specify linux-3.1.tar.bz2 which is what I have dumped into my ~/cross/src directory, and is what gets picked up for the builds.

For distcc, I've only tried running the daemon on Arch x86 once before and it was a complete failure. My computers run Kubuntu and things just work. So far, I don't think anyone has successfully set things up to do this using Arch.

I did notice this-
on dockstar -DHOST='"armv5tel-unknown-linux-gnu"' (part of a single compile command)
build on i7 arm-unknown-linux-gnueabi (the directory), CHHOST on dockstar is this too
Maybe some symlink would help? distcc is new to me too

Defines shouldn't impact the cross compiler, that's for the code it's actually building not what is being executed to build it. Using distcc with makepkg will adjust the build's PATH to put /usr/lib/distcc/bin first in line, so when configure/make looks for a compiler it finds /usr/lib/distcc/bin/{gcc,c++,etc.} and uses that, which combined with setting DISTCC_HOSTS in makepkg.conf will send those builds off to the host(s) specified. Very very very few program builds will look for a tuple-{gcc,etc} (ie. armv7l-unknown-linux-gnueabi-{gcc,etc}), and to send those over distcc you'd need to add symlinks to the /usr/lib/distcc/bin directory appropriately. That's not something I have done or needed to do, however.

OK, can now distcc to i7 (running archlinux), it's all a matter of path placement
Code: Select all
#!/bin/bash
[ -f /etc/conf.d/distccd ] && . /etc/conf.d/distccd

. /etc/rc.conf
. /etc/rc.d/functions
PATH=/home/cross/x-tools/arm-unknown-linux-gnueabi/bin:$PATH
.

Just comparing, compiling rasberry pi kernel on a dockstar takes 2.25 hours on a dockstar alone, and 30 minutes using distcc, think dockstar still has to do a fair chunk on it's own (uncompressing, LD, stripping, compressing) otherwise it would have been incredibly fast. I left out dockstar as on of the compiling hosts, and had j8 but i7 tells me it can handle 10 threads.
Comparing cross tools configs, apart from obvious floats/flags, I see this
CT_PARALLEL_JOBS=6 (on arm5)
CT_PARALLEL_JOBS=0 (on arm7hf)
