u-boot build issue about openbmc

[AdrianB-Flex]

Confirmed. Everyone, thanks for the help. The "How to build" section on the main facebook/openbmc page should be updated I think.

Building on a Ubuntu 14.04.5 machine and following the howto build section of this repo.

Hi @AdrianB-Flex, we can help, but I need more details about the error :)

[theopolis]

Here's the build that continually tries to build wedge100-image from the helium branch: https://jenkins.osquery.io/view/Other/job/openbmcHeliumBuildWedge100/

It runs:

export BOARD=wedge100
export OPENBMC=$PWD

sudo yum install -y perl-Thread-Queue gcc-c++ patch wget diffstat chrpath texinfo bzip2

git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/poky
cd poky
git clone -b krogoth --depth 1 https://github.com/openembedded/meta-openembedded.git
git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/meta-security
ln -s $OPENBMC meta-openbmc

export TEMPLATECONF=meta-openbmc/meta-facebook/meta-${BOARD}/conf
source ./oe-init-build-env

bitbake ${BOARD}-image

Sorry for the delay Teddy, I was on PTO latter half of last week. I am using fido not krogoth, that might be an issue. I'll give this a try.

[AdrianB-Flex]

Not seeing the meta-openbmc/meta-facebook folder. Is there a git clone missing? Before I had to do this:
git clone https://github.com/facebook/openbmc.git meta-openbmc

[theopolis]

Here's the meta-facebook folder: https://github.com/facebook/openbmc/tree/helium/meta-facebook

Would you mind starting from a clean working state and documenting the steps you're taking, I think that will help me debug too :)

[amithash]

@AdrianB-Flex if you are moving to krogoth from fido, you might also want to switch openbmc from the master to the helium branch.
git clone -b helium https://github.com/facebook/openbmc.git meta-openbmc
instead of
git clone https://github.com/facebook/openbmc.git meta-openbmc

[AdrianB-Flex]

Ahh, thanks Amit.

[AdrianB-Flex]

From a clean tree Ubuntu 14.04.5:
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib
build-essential chrpath libsdl1.2-dev xterm

git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/poky bolt-dev
cd bolt-dev
git clone -b krogoth --depth 1 https://github.com/openembedded/meta-openembedded.git
git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/meta-security
git clone -b helium https://github.com/facebook/openbmc.git meta-openbmc
export BOARD=wedge100
export TEMPLATECONF=meta-openbmc/meta-facebook/meta-${BOARD}/conf
source ./oe-init-build-env
bitbake ${BOARD}-image

[AdrianB-Flex]

And here's the error:

[tfangit]

@AdrianB-Flex The default gcc from poky krogoth branch is 5.x. However, your log shows as 4.9.2. Could u pls check why?

[AdrianB-Flex]

That's puzzling. When I do a gcc --version I get 6.2.0. This got pulled in from the apt-get install gcc-multilib from the yocto user guide. Not sure why 4.9.2 is getting selected.

[theopolis]

I'll try to reproduce on a Ubuntu 14.04 system tonight.

[renweihang]

When I cd to u-boot path and
'make fbwedge100_defconfig' && 'make'
also get this same problem:

How to fix the Assembler Error?

[theopolis]

Right, so this is a compiler issue. Is there the older GCC in your path?

On a new install of Ubuntu 14.04: https://jenkins.osquery.io/view/Other/job/openbmcUbuntuHeliumBuildWedge100/8/console

Using the build script from above.

[renweihang]

Thanks a lot , at first I use the poky fido branch,the gcc version is 4.9 .But now I use the krogoth branch, all going well,it can build success.

[AdrianB-Flex]

Frank, what distro/version did you use finally?

[renweihang]

Ubuntu-14.04.1-desktop-i386

Be honest, I did not find the real reason why I can build success finally, but , These are the steps I use to get things done:

sudo apt-get insatll gcc-arm-linux-gnueabi
sudo apt-get insatll g++-arm-linux-gnueabi
sudo apt-get install sed wget subversion git-core coreutils unzip gcc-multilib \
texi2html texinfo libsdl1.2-dev docbook-utils fop gawk python-pysqlite2
diffstat make gcc build-essential xsltproc g++ desktop-file-utils
chrpath libgl1-mesa-dev libglu1-mesa-dev autoconf automake groff libtool
xterm libxml-parser-perl vim-common xz-utils cvs tofrodos
libstring-crc32-perl ubuntu-minimal ubuntu-standard patch
libbonobo2-common libncurses5-dev \

git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/poky
cd poky
git clone -b krogoth --depth 1 https://github.com/openembedded/meta-openembedded.git
git clone -b krogoth --depth 1 https://git.yoctoproject.org/git/meta-security
git clone -b helium https://github.com/facebook/openbmc.git meta-openbmc

source oe-init-build-env
bitbake -k wedge100-image

[tfangit]

Switching to krogoth and start a new build directory shall fix this issue, as gcc 5.x is used in Krogoth.

@AdrianB-Flex Could you confirm if this fixed your build issue?
