You are comparing two different things. The MD5 checksum 14351800dc7c3896b060f1033c65aebc is being used by the script itself.
The content of blob-shasums is a SHA1.

Hi
Thank you for that correction. Im now able to get a .OK statement in the start of the download of the blobs.
Allthrough the MD5 error is still present.
To me its not clear why the MD5 checksum doesn’t match. I found the second number: 1435… inside the blobfile when i decompressed it…
but why does the calculated checksum not match with the checksum inside the file?
I calculated with terminal:
Can somebody give a answer to that mystery?
It worked until about 11 days ago when i built my last B2G Tests, as you can see in the top of this post…
Regards, Novski
This script is unrelated to B2G, we cannot help you. Please make sure you have no problem with your internet connection, try to download by hand from a browser, and/or ask FP2 people.
Ok what i we found to be the problem may be of interrest for other OSX builds as well.
It seams like osx calculates the checksum differently then linux does. Its been compared to ubuntu and freeBSD as well and it differs slightly.
Find the discussion on fairphone forum tread: https://forum.fairphone.com/t/blobs-md5-checksum-doenst-match/18107/7
So if the makeself of the blob is checking md5 checksum it will not work to build on osx…
Maybe somebody here has the skills to solve such a problem somehow, otherwise i have to stick to my Ubuntu VM, heating my machine like a stove 
Regards, Novski
That’s an upstream issue, we really cannot afford spending time on fixing this right now :/. Not to mention it’s well known building B2G on OSX might fail.
hi, i added the informaiton i experienced with osx and fairphone2 blobs to the mdn and desided to go back to ubuntu in a VM. Therefor i installed a latest 16.4 LTS with the mdn prerequisite as guide, but ran in to a package that doesn’t whant to install… its this one:
zlib1g-dev:i386
I don’t find any informaiton about that package.
Does anybody have a 16.4 installed and is able to try “sudo apt-get install zlib1g-dev:i386” ?
I have no problem to go with a 14.4 but, i wold like to correct the mdn, it might beware others running in to the same…
Thanks, Novski
Are you sure dpkg has been configured properly? It should make use of multiarch.
i followed this: https://developer.mozilla.org/en-US/docs/Mozilla/B2G_OS/B2G_OS_build_prerequisites

First, run the following commands to set the required architectures:
sudo dpkg --add-architecture i386

Well obviously this multiarch package is broken on 16.04 but 14.04 LTS is still the one recommended as far as I can tell :-/

ok. 
back to the stable side of life. Thank you! 
cheers, novski
Hi @Novski 
Any update here ?
Do you want any help ?
Also, if you have news/question from the Fairphone community, feel free to share them 
Hi Lapineige
Im still stuck with the white layer on top of menues… I made a new build environement in a fresh vm yesterday and build a pine-kanikani from scratch but still its not solved. So if you have me the code snipets to fetch those updated files i wold apreciate…
Thanks, Novski
You mean the git commands to apply the patches ?
yes, yes if possible i wold realy apreciate… 
As a general hint, you should learn how to use git, it’s always something useful
Here are some useful links:
https://rogerdudler.github.io/git-guide/
A basic thing when you have .patch files, to apply them, is to use git am YourPatchName.patch.
Hi i think its time to spend some more investigation in this.
I wold realy like to get FP2 available over b2g-installer so my plan was to build first a blobfull image and test it. Then create the blobfree build and test that. Both didn’t work since the first time when i found the white layer, and i don’t understand where the leak/break is.
So im searchig for help in terms of guiding me through the code.
What i have done until now is:
$ sudo dpkg --add-architecture i386sudo dpkg --add-architecture amd64sudo apt-get install --no-install-recommends autoconf2.13 bison bzip2 ccache curl flex gawk gcc g++ g++-multilib git lib32ncurses5-dev lib32z1-dev libgconf2-dev zlib1g:amd64 zlib1g-dev:amd64 zlib1g:i386 zlib1g-dev:i386 libgl1-mesa-dev libx11-dev make zip lzop libxml2-utils openjdk-7-jdk nodejs unzip python
$ ccache -M 50G
$ git clone git://github.com/mozilla-b2g/B2G.git && cd B2G $ hg clone https://hg.mozilla.org/projects/pine/ pine $ ./config.sh fairphone2
$ vim .repo/manifests/base.xml
changed this line:
<project name="gaia" path="gaia" remote="mozillaorg" revision="kanikani" /> $ cd gaia $ git reset --hard mozillaorg/kanikani $ cd ..
$ vim .userconfig
Pasted this to the file:
export B2G_DIR=${B2G_DIR:-$(cd $(dirname $0); pwd)} echo "B2G_DIR = ${B2G_DIR}" export GECKO_PATH=${B2G_DIR}/pine echo "GECKO_PATH = ${GECKO_PATH}"
./build.sh
./flash.sh
It runns through smothly but the phone doesn’t boot to gecko. It seams to loop in the FP2 specific “loading…” page befor the lockscreen should apear.
So there are 2 questions:
- how can i apply the needed patches from.
( i know now that its < git am > but i asume it needs a url or a Bug nr. that i can’t find out how to make it work… ) - What can prevent it from not booting? That may be related to point 1…
By the way those Tutorials don’t go in to patching. But i did learn some usefull things…
Thanks for a update.

I now tried something else. Masterbranch

The failure is during gecko build. You should do as suggested and
./build.sh -j1 to see it.
