It provides a way to be reasonably sure that the +executables are really built from source on github. It also makes sure that +the same, tested dependencies are used and statically built into the executable. + +Multiple developers build the source code by following a specific descriptor +("recipe"), cryptographically sign the result, and upload the resulting signature. +These results are compared and only if they match, the build is accepted and uploaded +to bitcoin.org. + +More independent gitian builders are needed, which is why I wrote this +guide. It is preferred to follow these steps yourself instead of using someone else's +VM image to avoid 'contaminating' the build. + +[1] For all platforms except for MacOSX, at this point.

Type/paste the following in the terminal: + + +```bash +apt-get install git ruby sudo apt-cacher-ng qemu-utils debootstrap lxc python-cheetah parted kpartx bridge-utils +adduser debian sudo +``` + +When you get a colorful screen with a question about the 'LXC directory', just +go with the default (`/var/lib/lxc`). + +Then set up LXC and the rest with the following is a complex jumble of settings and workarounds: + +```bash +# the version of lxc-start in Debian 7.4 needs to run as root, so make sure +# that the build script can exectute it without providing a password +echo "%sudo ALL=NOPASSWD: /usr/bin/lxc-start" > /etc/sudoers.d/gitian-lxc +# add cgroup for LXC +echo "cgroup /sys/fs/cgroup cgroup defaults 0 0" >> /etc/fstab +# make /etc/rc.local script that sets up bridge between guest and host +echo '#!/bin/sh -e' > /etc/rc.local +echo 'brctl addbr br0' >> /etc/rc.local +echo 'ifconfig br0 10.0.3.2/24 up' >> /etc/rc.local +echo 'exit 0' >> /etc/rc.local +# make sure that USE_LXC is always set when logging in as debian +echo 'export USE_LXC=1' >> /home/debian/.profile +reboot +``` + +At the end the VM is rebooted to make sure that the changes take effect. + +**Note**: If you're following this guide on a physical system instead of a VirtualBox VM you could use `10.0.2.2` instead +of `10.0.3.2` in the above `ifconfig` line. This avoids having to patch gitian-builder in next section. + +Installing gitian +------------------ + +Re-login as the user `debian` that was created during installation. +The rest of the steps in this guide will be performed as that user. + +There is no `python-vm-builder` package in Debian, so we need to install it from source ourselves, + +```bash +wget http://archive.ubuntu.com/ubuntu/pool/universe/v/vm-builder/vm-builder_0.12.4+bzr489.orig.tar.gz +echo "ec12e0070a007989561bfee5862c89a32c301992dd2771c4d5078ef1b3014f03 vm-builder_0.12.4+bzr489.orig.tar.gz" | sha256sum -c +# (verification -- must return OK) +tar -zxvf vm-builder_0.12.4+bzr489.orig.tar.gz +cd vm-builder-0.12.4+bzr489 +sudo python setup.py install +cd .. +``` + +**Note**: When sudo asks for a password, enter the password for the user *debian* not for *root*. + +Clone the git repositories for bitcoin and gitian, + +```bash +git clone https://github.com/devrandom/gitian-builder.git +git clone https://github.com/bitcoin/bitcoin +``` + +We need to change the guest IP range for the gitian builder because otherwise it will +collide with VirtualBox its NAT IP range. Gitian does not have a way yet to configure +this, so we need to patch the IPs using `sed`. This is not nice but it will +have to do for now... (a [pull request +(#52)](https://github.com/devrandom/gitian-builder/pull/52) to make this +configurable without patching has been submitted): + +```bash +sed -i 's/10.0.2.2/10.0.3.2/g' gitian-builder/target-bin/bootstrap-fixup +sed -i 's/10.0.2.5/10.0.3.5/g' gitian-builder/etc/lxc.config.in +``` + +*note* After you update the gitian-builder repository, you may need to repeat these manual changes. + +Setting up gitian images +------------------------- + +Gitian needs virtual images of the operating system to build in. +Currently this is Ubuntu Precise for both x86 architectures. +These images will be copied and used every time that a build is started to +make sure that the build is deterministic. +Creating the images will take a while, but only has to be done once. + +Execute the following as user `debian`: + +```bash +cd gitian-builder +bin/make-base-vm --lxc --arch i386 --suite precise +bin/make-base-vm --lxc --arch amd64 --suite precise +``` + +There will be a lot of warnings printed during build of the images. These can be ignored. + +**Note**: When sudo asks for a password, enter the password for the user *debian* not for *root*. + +Getting and building the inputs +-------------------------------- + +In [doc/release-process.md](release-process.md) in the bitcoin repository under 'Fetch and build inputs'. +you will find a list of `wget` commands that can be executed to get the dependencies. + +I needed to add `--no-check-certificate` to the OpenSSL wget line to make it work. +Likely this is because the ca-certificates in Debian 7.4 is fairly old. This does not create a +security issue as the gitian descriptors check integrity of the input archives and refuse to work +if any one is corrupted. + +After downloading the archives, execute the `gbuild` commends to build the dependencies. +This can take a long time, but only has to be done when the dependencies change, for example +to upgrade the used version. + +**Note**: Do not forget to copy the result from `build/out` to `inputs` after every gbuild command! This will save +you a lot of time. + +At any time you can check the package installation and build progress with + +```bash +tail -f var/install.log +tail -f var/build.log +``` + +To make sure that the output is exactly the same, and that the time, date, locale and +even the ordering of files in the file system doesn't influence the result, +some special precautions are taken. This means that the result is expected to +be the same every time. The expected SHA256 hashes of the intermediate +inputs (at the time of release 0.9.0) are: + + 05fe8e9aef00d295f24a94deef7d3a918af5aeef371ba57fdd5a6acd8c51f6cb bitcoin-deps-linux32-gitian-r3.zip + 4227aa9d9fedbb4265b8d10a4f78b7435f34b00a54eb4d662bf78f59c6e70c27 bitcoin-deps-linux64-gitian-r3.zip + f29b7d9577417333fb56e023c2977f5726a7c297f320b175a4108cf7cd4c2d29 boost-linux32-1.55.0-gitian-r1.zip + 88232451c4104f7eb16e469ac6474fd1231bd485687253f7b2bdf46c0781d535 boost-linux64-1.55.0-gitian-r1.zip + 60dc2d3b61e9c7d5dbe2f90d5955772ad748a47918ff2d8b74e8db9b1b91c909 boost-win32-1.55.0-gitian-r6.zip + f65fcaf346bc7b73bc8db3a8614f4f6bee2f61fcbe495e9881133a7c2612a167 boost-win64-1.55.0-gitian-r6.zip + 0ba0855e1084132d05fd8687c19d8430b91f6c410a9ab7938e4fea650c2b22c8 bitcoin-deps-win32-gitian-r10.zip + 5f9ffba0c13ddefc1d339f66ab973ea64623c9cc1f9078cb2b145bce86bd28e2 bitcoin-deps-win64-gitian-r10.zip + 963e3e5e85879010a91143c90a711a5d1d5aba992e38672cdf7b54e42c56b2f1 qt-win32-5.2.0-gitian-r2.zip + 751c579830d173ef3e6f194e83d18b92ebef6df03289db13ab77a52b6bc86ef0 qt-win64-5.2.0-gitian-r2.zip + e2e403e1a08869c7eed4d4293bce13d51ec6a63592918b90ae215a0eceb44cb4 protobuf-win32-2.5.0-gitian-r4.zip + a0999037e8b0ef9ade13efd88fee261ba401f5ca910068b7e0cd3262ba667db0 protobuf-win64-2.5.0-gitian-r4.zip + +Building Bitcoin +---------------- + +To build Bitcoin (for Linux and/or Windows) just follow the steps under 'perform +gitian builds' in [doc/release-process.md](release-process.md) in the bitcoin repository. + +Output from `gbuild` will look something like + + Initialized empty Git repository in /home/debian/gitian-builder/inputs/bitcoin/.git/ + remote: Reusing existing pack: 35606, done. + remote: Total 35606 (delta 0), reused 0 (delta 0) + Receiving objects: 100% (35606/35606), 26.52 MiB | 4.28 MiB/s, done. + Resolving deltas: 100% (25724/25724), done. + From https://github.com/bitcoin/bitcoin + ...
