Building all packages using the released toolchain

I am new to yocto, I have installed yacto on Fedora 12.

I was trying to follow the steps in the getting started guide and was trying a build with "bitbake make-native" and got some build errors in "elfutils", but it was using the compiler in my Fedora distribution. I have also downloaded the toolchain in /opt/poky, and manually reran configure in the elfutils to use the compilers in /opt/poky and it built fine.

What config changes do I have to make so that bitbake builds everything using the toolchain compilers rather than the default gcc? (i.e have it run each configure script so that it specifies the toolchain compiler rather than use the default compiler)

I did run the environment script

/opt/poky/environment-setup-i586-poky-linux

but apparently more is required

Thanks in advance,

Rick.

The make-native is required on Fedora14. So you don't need that step and Instead you could directly:
Bitbake poky-image-sato

Btw, could you post your errors?

For native packages, yes the host compiler from your distribution is expected btw.

This makes me a bit confused what you're tempting to do. Did you try to build a complete sato image, or want to use pre-built image and downloard toolchain to develop application? For the former you don't need the later /opt/poky stuff. For the latter you don't need build any native packages since all the toolchains are already there.

Thanks

Ok. I was not sure if it was specific to Fedora 14 or not. The Quick Start mentions Fedora 14 "or another distribution with GNU make 3.82" which is what I have on Fedora 12, so I thought this step would be required.

Why is this only required on Fedora 14?

BTW, I did run Bitbake poky-image-sato, and I got a similar error to below, but in a different directory

My gcc version is 4.4.4, the latest available from yum update for Fedora
12. My poky-4.0-build/conf/local.conf is attached.

My error building the elfutils directory is shown below:

Long term what I want to do is build an embedded linux system from scratch to run on our own hardware.

I only found out about yacto today through searching around the Intel EDC web site. We have the Intel Atom based eval board (EG20T) with Tunnel Creek and saw today that this is a newly supported platform in yocto so I was very anxious to try it out. I thought it would be best to first try and build a standard configuration first just to learn the
tool, so short term, yes, I want to build the complete sato image. We
are building our own Intal Atom/ Tunnel Creek embedded platform and on the surface it looks like yacto is a perfect fit. Trying to decide now if commercial linux is required or if something like yocto will work.

For developing embedded products I like the idea of having an "isolated" toolchain so I can built a consistent product, regardless of what updates I do to my laptop distribution. So is there a way to configure yocto to use the /opt/poky toolchain rather than the fedora tools?

Yes, it's make 3.82 related. My gut-feeling is that FC12 should have an older version which ends up wrong here. :-)

OK, I remembered that there're a series of patches to make FC14 happy after Laverne release:

	https://lists.yoctoproject.org/pipermail/poky/2010-December/001023.html

So it's better you can try the poky master for your experiment here:
git://git.pokylinux.org/poky.git

Thanks

Yes.

Poky.git is a repo which contains a bunch of branches. One simple way you can verify is to use "git branch", and if "*master" is shown then you're using the master branch.

If it still doesn't work for you, it ends up to other issues. I did another round of read on original fedora 14 mail thread. It looks that your error is a little bit different to that one:

	(yours) ./ld: invalid option -- 'p'
	(original) ./ld: unrecognized option '--no-add-needed'

The common point is that elfutils's own ./ld is used which supports less options and thus Triggers the error. You can look at the bugzilla here:

	http://bugzilla.pokylinux.org/show_bug.cgi?id=572

Wolfgang has "." included in his PATH which is before /bin and /usr/bin. Ideally this has been fixed by commit 68030f4 (I had a quick test that "." does be warned out in master branch). Yours looks similar and I'm not sure how local ".ld" is referenced here. Could you post your PATH variable from your build directory?

BTW, I missed the latter part in your last post, and thus reply here:

http://yoctoproject.org/ is the project homepage.

Good to know that. :-)

Yes, Yocto is a perfect choice for your prototype purpose here.

For this you can refer to Yocto development manual:
http://www.yoctoproject.org/docs/poky-ref-manual/poky-ref-manual.html

CH5 provides guidance to use /opt/poky toolchain for application development. However we don't have doc now about using an external toolchain to compile the whole yocto yet, though it does be supported. The closest info you could refer to now is the openembedded manual (CH5.5). Could you fill a bug for this documentation requirement? We'll address that in coming release.

But there may be one confusion I'd like to clarify here. What /opt/poky contains are a set of cross-toolchains which are used to compile binaries running on the target machine. For them Fedora doesn't provide. On the other hand, for the make-native/elfutils-native, which are running on the build host, they have to be compiled with Fedora toolchains which is the starting point of the whole yocto build process. :-)

Thanks,
Kevin
