Hello world-Checksum error

Hello world-Checksum error

Hi all,

I am trying to add Hello world recipe, everything was going good but after
giving bitbake <target> command it breaks with the following error:

siguser@siguser:~/yocto2013-05-08/poky/build$ *bitbake gumstix-console-image
*

ERROR: ExpansionError during parsing
/home/siguser/yocto2013-05-08/poky/meta-bebot/recipes-bebot/hello/hello.bb:
Failure expanding expression ${@bb.fetch.get_checksum_file_list(d)} which
triggered exception NoMethodError: Could not find a fetcher which supports
the URL: '${ftp://ftp.gnu.org/gnu}/hello/hello-${2.7}.tar.gz'
ERROR: Command execution failed: Exited with 1


*My hello.bb file is*:

DESCRIPTION = "GNU Helloworld application"
SECTION = "examples"
LICENSE = "GPLv3+"
LIC_FILES_CHKSUM = "file://COPYING;md5=d32239bcb673463ab874e80d47fae504"
PR = "r0"
SRC_URI = "${ftp://ftp.gnu.org/gnu}/hello/hello-${2.7}.tar.gz"
inherit autotools gettext

I downloaded hello-2.7.tar.gz -> extracted -> ran md5sum against COPYING ->
got md5 -> added that md5 to my hello.bb file.
Any ideas where I am doing wrong?

Hi,

Please remove the $ sign in SRC_URI and retry building the package.. I
think it is the issue

I removed $ sign in SRC_URI  and ran build again, following is the same
error:

ERROR: ExpansionError during parsing
/home/siguser/yocto2013-05-08/poky/meta-bebot/recipes-bebot/hello/hello.bb:

I think you need to add the md5 sum of source tarball as well, something 
like
SRC_URI[md5sum] = "b93435488942486c8d0ca22e8f768034"

That should be:

SRC_URI = "ftp://ftp.gnu.org/gnu}/hello/hello-2.7.tar.gz"

Hi Paul,

It's the same error:

ERROR: ExpansionError during parsing
/home/siguser/yocto2013-05-08/poky/meta-bebot/recipes-bebot/hello/hello.bb:
Failure expanding expression ${@bb.fetch.get_checksum_file_list(d)} which
triggered exception NoMethodError: Could not find a fetcher which supports
the URL: '{ftp://ftp.gnu.org/gnu}/hello/hello-2.7.tar.gz'
ERROR: Command execution failed: Exited with 1

I found something similar at the end of this:

https://lists.yoctoproject.org/pipermail/yocto/2012-January/006660.html

Any hints?

Thank You,

Looks like you still have {} in your SRC_URI, use:

SRC_URI = "ftp://ftp.gnu.org/gnu/hello/hello-2.7.tar.gz"

Hi all,

Error corrected. Thank You.

Do we need to add IMAGE_INSTALL += " hello " and EXTRA_IMAGE_FEATURES += "
hello " to yocto/build/conf/local.conf or yocto/poky/build/conf/local.conf
 before running build?

If you want it installed into an image, yes. However, IMAGE_INSTALL += "hello" 
in local.conf won't work, because it will be overridden by the setting of 
IMAGE_INSTALL in the image recipe itself, since local.conf will be parsed 
first. You need to do this instead in local.conf:

IMAGE_INSTALL_append = " hello"

(note the leading space, this is important with _append as _append does not 
add a space for you). _append operations are deferred until the end of parsing 
and thus will be applied even if the value is set with = afterwards as in this 
case.

Also, EXTRA_IMAGE_FEATURES += " hello " won't do anything since "hello" is not 
a valid image feature, it's a package. Appending it to IMAGE_INSTALL is enough 
to have it installed into the image.

Cheers,
Paul

Hi all,

I am in a serious *problem* of unable to add a recipe and build an image.

previously, I successfully build *gumstix-console-image* and I have created
*meta-bebot* folder for my recipe.

My Yocto tree as follows:

Yocto
 --build
   --conf
       --bblayers.conf ( I added /home/siguser/yocto2013-05-08/poky/*
meta-bebot* \ ) path
       --local.conf ( I added IMAGE_INSTALL_append = " hello" ) under
*Additional
image features*
   --downloads
   --tmp
   --
   --

 --poky
    --bitbake
    --build
    --documentation
    --meta
    --*meta-bebot*
*        --conf*
*            --bblayers.conf *(I added  /home/siguser/yocto2013-05-08/poky/*
meta-bebot* \ ) path
*            --layer.conf *(I added BBFILE_COLLECTIONS += "*meta-bebot*"
                                             BBFILE_PATTERN_*meta-bebot* :=
"^${LAYERDIR}/"
                                             BBFILE_PRIORITY_*meta-bebot* =
"7" )
*        --recipes-bebot*
*             --hello*
*                --hello.bb*
    --meta-gumstix
    --meta-gumstix-extras
    --meta-hob
    --meta-openembedded
    --
    --remaining other folders..


When I try to build image *bitbake gumstix-console-image*
                      again it throws this error: *ERROR: Nothing PROVIDES
'gumstix-console-image'*

I do not know where I am doing wrong or what the problem is. I would be
greatly helpful if anyone can give some inputs.

Thank You,

Regards,
Zafrullah Syed

If I understand correctly from the above that you have put bblayers.conf in 
conf/ under your meta-bebot layer, that is not correct. bblayers.conf needs to 
be under conf/ in your build directory as usual.

Are you also extending BBFILES and BBPATH in your meta-bebot/conf/layer.conf?

BitBake uses BBFILES to find recipes; each layer's layer.conf typically extends 
BBFILES to find the recipes within the layer. If you are receiving this error 
it means (as you might expect) that BitBake cannot find a provider for the 
specified target. This is either because your bblayers.conf no longer adds the 
path to meta-gumstix to BBLAYERS, or because BBFILES is being reset so that it 
no longer includes the path within meta-gumstix to find the gumstix-console-
image recipe. Please check that you don't have a duplicate bblayers.conf (as 
mentioned above) and that your meta-bebot/conf/layer.conf is appropriately 
extending BBFILES (see other layers for examples).

Paul

my bblayers.conf file lies in  poky/meta-bebot/conf/bblayers.conf. do I
need to remove this file and keep it in which build folder? I mean /yocto/*
build*/conf/bblayers.conf or /yocto/*poky*/build/conf/bblayers.conf?

My meta-bebot/conf/layer.conf is as follows:

# We have a conf directory, append to BBPATH
BBPATH .= ":${LAYERDIR}"

# We have a recipes directory, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb ${LAYERDIR}/recipes-*/*/*.bbappend"

BBFILE_COLLECTIONS += "meta-bebot"
BBFILE_PATTERN_meta-bebot := "^${LAYERDIR}/"

Yes, conf/bblayers.conf is supposed to be in the build directory; and 
whichever build directory you are actually using. The build directory can be 
anywhere, but you shouldn't really have two build directories unless you know 
what you are doing - did you perhaps run oe-init-build-env with no arguments 
in two different places? I suspect this is what has happened.

I think yes. I usually give just *source oe-init-build-env *command, this
is how i used earlier and failed. May be that is the reason it has created
another build directory in /poky.
What should be the command before building? i guess this(
TEMPLATECONF=meta-gumstix-extras/conf
source ./poky/oe-init-build-env ). so, every time i just need to give
TEMPLATECONF  command before building?

Lastly, my meta-bebot directory should be as following ?

/poky
  --meta-bebot
      --conf
         --layer.conf
  --recipes-bebot
    --hello
      --hello.bb

and meta-bebot path should be set in bblayers.conf file?

Please correct me if i am going wrong.

Thank You.

You need to run oe-init-build-env at the start of every session yes, but you 
shouldn't need to specify TEMPLATECONF except when you first create the build 
directory. The important thing is you need to be in the same directory when 
you run oe-init-build-env *or* specify the path to the build directory as a 
parameter.

If you have recipes-bebot under meta-bebot, yes.

Yes.

We have a script for that in our build directory that we source and that
calls oe-init-build-env relatively. With that the chance to do a mistake
is minimized. It uses a relative path to oe-init-build-env.
We also use relative paths to all the layers we use in out bblayers.conf.
As reference we use ${TOPDIR}, which is the build directory.

METADIR_BUILDSYSTEMBASE="${TOPDIR}/../buildsystem_base"
BBLAYERS ?= " \
  ${METADIR_BUILDSYSTEMBASE}/poky-dylan-9.0.0/meta \
  ${METADIR_BUILDSYSTEMBASE}/poky-dylan-9.0.0/meta-yocto \
  ${METADIR_BUILDSYSTEMBASE}/poky-dylan-9.0.0/meta-yocto-bsp \
  ${METADIR_BUILDSYSTEMBASE}/meta-openembedded/meta-oe \
  ${METADIR_BUILDSYSTEMBASE}/meta-ti \
  "

The oeenv script is no rocket science and mostly looks like this:
----------[oeenv]-------------
#!/bin/sh
if [ -z "$ZSH_NAME" ] && [ "x$0" = "x./oeenv" ]; then
   echo "Error: This script needs to be sourced. Please run as '. ./oeenv'"
else
# path to poky relative to build dir
   RELPATHTOOEENV="../buildsystem_base/poky-dylan-9.0.0/oe-init-build-env"

   if [ -n "$BASH_SOURCE" ]; then
      _BUILDROOT="`dirname $BASH_SOURCE`"
   else
      _BUILDROOT="`pwd`"
   fi
   _BUILDROOT=`readlink -f "$_BUILDROOT"`

   source "$_BUILDROOT"/"$RELPATHTOOEENV" "$_BUILDROOT"

   unset _BUILDROOT
   unset RELPATHTOOEENV
fi

Hi,

I followed all the instructions and i started my build again. Build
successfully started and struck with Hello md5sum error.

ERROR: Fetcher failure for URL: '
ftp://ftp.gnu.org/gnu/hello/hello-2.7.tar.gz'. No checksum specified for
/home/siguser/yocto2013-05-21/build/downloads/hello-2.7.tar.gz, please add
at least one to the recipe:
SRC_URI[md5sum] = "fc01b05c7f943d3c42124942a2a9bb3a"
SRC_URI[sha256sum] =
"fd593b5bcf6d1bb6d7d1bb7eefdccdc0010cf2c4985ccb445ef490f768b927c0"


I downloaded hello-2.7 from ftp://ftp.gnu.org/gnu/hello/ unzipped and ran
md5sum against COPYING file. Each file has different md5sum, which md5sum
should I include in my hello.bb file?

*My hello.bb file*:

DESCRIPTION = "GNU Helloworld application"
SECTION = "examples"
LICENSE = "GPLv3+"
LIC_FILES_CHKSUM = "file://COPYING;md5=fc01b05c7f943d3c42124942a2a9bb3a"
PR = "r0"
SRC_URI = "ftp://ftp.gnu.org/gnu/hello/hello-2.7.tar.gz"

Re: Hello world-Checksum error

[Michael Stickel]

Hi

This is the checksum over the archive. If this is your own recipe and 
has no checksum yet, just add the two lines to your recipe (for example 
right after the SRC_URI line):

SRC_URI[md5sum] = "fc01b05c7f943d3c42124942a2a9bb3a"
SRC_URI[sha256sum] = 
"fd593b5bcf6d1bb6d7d1bb7eefdccdc0010cf2c4985ccb445ef490f768b927c0"

The checksum is used to check if the archive is broken or the wrong version.

This is something different than the LIC_FILES_CHKSUM, that checks if 
license in the archive is what the recipe expects.

Best regards
Michael
