Crosscompling wiht distcc

[disfido]

Hi, I'm trying to cross-compile software with distcc for our raspberrypi:

server machine: bridged Virtualbox Archlinux 64
daemon machine: raspberry-pi

1) I used instruction from the wiki: https://wiki.archlinux.org/index.php/Distcc
2) I created my toolchains using AUR PKGBUILDS:

• arm-linux-gnueabi-binutils
• arm-linux-gnueabi-gcc

3) So after successful compilation/installation did symlinks to arm-linux-gnueabi's binaries and add the path to PATH variable on the server machine.

4) I did makepkg from daemon machine (raspberry pi) but only some c sources are compiled, for others I received the distcc this error:
$this->bbcode_second_pass_code('', 'distcc[8615] (dcc_build_somewhere) Warning: failed to distribute, running locally instead')

and finally this:
$this->bbcode_second_pass_code('', 'CMakeFiles/oscam.dir/oscam.o: file not recognized: File format not recognized')

When the compilation starts I had this on the server machine:
$this->bbcode_second_pass_code('', ' (dcc_job_summary) client: 192.168.0.2:38206 COMPILE_ERROR exit:1 sig:0 core:0 ret:0 time:4ms gcc /home/adriano/oscam-svn/src/oscam-build/CMakeFiles/CMakeTmp/testCCompiler.c')

I tried too use this how to http://archlinuxarm.org/developers/dist ... -compiling
width pre-compiled x-tools toolchain but I had the same error...

I followed the guides and got it working fine (have compiled a kernel a couple of times).

Just to get things straight, as your terminology is confusing:

- The daemon machine is not the pi, it's your server box, right? The Pi just has "distcc" and DISTCC_HOSTS set in makepkg.conf

- You have the path set to the x-tools chain on the server box set correctly?

e.g. export PATH="/opt/x-tools6h/arm-unknown-linux-gnueabi/bin:$PATH" in /etc/rc.d/distccd on the server?

*Edit: I moved my x-tools to /opt and ran some finds to fix permissions.

- The x-tools stuff is executable by the user that distccd runs as (e.g. nobody)?

I'm just guessing here (not even sure what you're trying to compile)...

But are you running the newly released Arch ARM image (the hard float one), or one you've been running for a while and have kept updated?

The CFLAGS etc in makepkg.conf for the latest OS and x-tools uses hard float, different -march etc.

If you are using all the latest - make distclean and try again?

[disfido]

Yes I'm using the latest image archlinux-hf-2012-09-18.img with this flags in makepkg.conf:

$this->bbcode_second_pass_code('', '
CFLAGS="-march=armv6 -mfloat-abi=hard -mfpu=vfp -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2"
CXXFLAGS="-march=armv6 -mfloat-abi=hard -mfpu=vfp -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2"
')

I imagined that x-tools was for old images, for this reason I compiled the cross-tools from AUR, but I have also problems...

Maybe I must compile arm-linux-gnueabi-gcc with hard float support...but how?

[pezz]

Dunno mate, I'm using the latest pre-compiled x-tools and I can distcc fine.

Sorry. :/

[disfido]

but are you using the latest xtools with armv6 FLAGS?

[pezz]

Yep.

[WarheadsSE]

The armv6h x-tools that we have zipped on that page are what we used to make the v6h repo.

I prefer to use PKGBUILDs (the arch-way )
so I solved recompiling the arm-linux-gnueabi-* packages from AUR with this flags:

$this->bbcode_second_pass_code('', '
--with-arch=armv6
--with-float=hard
--with-fpu=vfp
')

The problem is the distccd.service for systemd.
I set PATH=/mytoolchain/:$PATH
And next restart distccd: systemd restart distccd

but it starts with the original path:
$this->bbcode_second_pass_code('', '
distccd[20612] (dcc_setup_daemon_path) daemon's PATH is /usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/usr/bin/core_perl
')

If starts it manually all works fine...suggestions?
