However, you will likely +need this entry for better desktop integration. Please see [this +section](#add-an-etcprofiled-entry) for instructions on how to add a +`/etc/profile.d/guix.sh` entry. + +Regardless of which installation option you chose, the changes to +`/etc/profile.d` will not take effect until the next shell or desktop session, +so you should log out and log back in. + +## Option 3: Using fanquake's Docker image + +Please refer to fanquake's instructions +[here](https://github.com/fanquake/core-review/tree/master/guix). + +Note that the `Dockerfile` is largely equivalent to running through the binary +tarball installation steps. + +## Option 4: Using a distribution-maintained package + +Note that this section is based on the distro packaging situation at the time of +writing (July 2021).

Previous experience with using autotools-style build +systems to build packages from source will be helpful. *hic sunt dracones.* + +I strongly urge you to at least skim through the entire section once before you +start issuing commands, as it will save you a lot of unnecessary pain and +anguish. + +### Installing common build tools + +There are a few basic build tools that are required for most things we'll build, +so let's install them now: + +Text transformation/i18n: +- `autopoint` (sometimes packaged in `gettext`) +- `help2man` +- `po4a` +- `texinfo` + +Build system tools: +- `g++` w/ C++11 support +- `libtool` +- `autoconf` +- `automake` +- `pkg-config` (sometimes packaged as `pkgconf`) +- `make` +- `cmake` + +Miscellaneous: +- `git` +- `gnupg` +- `python3` + +### Building and Installing Guix's dependencies + +In order to build Guix itself from source, we need to first make sure that the +necessary dependencies are installed and discoverable. The most up-to-date list +of Guix's dependencies is kept in the ["Requirements" +section](https://guix.gnu.org/manual/en/html_node/Requirements.html) of the Guix +Reference Manual. + +Depending on your distribution, most or all of these dependencies may already be +packaged and installable without manually building and installing. + +For reference, the graphic below outlines Guix v1.3.0's dependency graph: + + + +#### Guile + +##### Choosing a Guile version and sticking to it + +One of the first things you need to decide is which Guile version you want to +use: Guile v2.2 or Guile v3.0. Unlike the python2 to python3 transition, Guile +v2.2 and Guile v3.0 are largely compatible, as evidenced by the fact that most +Guile packages and even [Guix +itself](https://guix.gnu.org/en/blog/2020/guile-3-and-guix/) support running on +both. + +What is important here is that you **choose one**, and you **remain consistent** +with your choice throughout **all Guile-related packages**, no matter if they +are installed via the distribution's package manager or installed from source. +This is because the files for Guile packages are installed to directories which +are separated based on the Guile version. + +###### Example: Checking that Ubuntu's `guile-git` is compatible with your chosen Guile version + +On Ubuntu Focal: + +```sh +$ apt show guile-git +Package: guile-git +... +Depends: guile-2.2, guile-bytestructures, libgit2-dev +... +``` + +As you can see, the package `guile-git` depends on `guile-2.2`, meaning that it +was likely built for Guile v2.2. This means that if you decided to use Guile +v3.0 on Ubuntu Focal, you would need to build guile-git from source instead of +using the distribution package. + +On Ubuntu Hirsute: + +```sh +$ apt show guile-git +Package: guile-git +... +Depends: guile-3.0 | guile-2.2, guile-bytestructures (>= 1.0.7-3~), libgit2-dev (>= 1.0) +... +``` + +In this case, `guile-git` depends on either `guile-3.0` or `guile-2.2`, meaning +that it would work no matter what Guile version you decided to use. + +###### Corner case: Multiple versions of Guile on one system + +It is recommended to only install one version of Guile, so that build systems do +not get confused about which Guile to use. + +However, if you insist on having both Guile v2.2 and Guile v3.0 installed on +your system, then you need to **consistently** specify one of +`GUILE_EFFECTIVE_VERSION=3.0` or `GUILE_EFFECTIVE_VERSION=2.2` to all +`./configure` invocations for Guix and its dependencies. + +##### Installing Guile + +Guile is most likely already packaged for your distribution, so after you have +[chosen a Guile version](#choosing-a-guile-version-and-sticking-to-it), install +it via your distribution's package manager. + +If your distribution splits packages into `-dev`-suffixed and +non-`-dev`-suffixed sub-packages (as is the case for Debian-derived +distributions), please make sure to install both. For example, to install Guile +v2.2 on Debian/Ubuntu: + +```sh +apt install guile-2.2 guile-2.2-dev +``` + +#### Mixing distribution packages and source-built packages + +At the time of writing, most distributions have _some_ of Guix's dependencies +packaged, but not all. This means that you may want to install the distribution +package for some dependencies, and manually build-from-source for others. + +Distribution packages usually install to `/usr`, which is different from the +default `./configure` prefix of source-built packages: `/usr/local`. + +This means that if you mix-and-match distribution packages and source-built +packages and do not specify exactly `--prefix=/usr` to `./configure` for +source-built packages, you will need to augment the `GUILE_LOAD_PATH` and +`GUILE_LOAD_COMPILED_PATH` environment variables so that Guile will look +under the right prefix and find your source-built packages. + +For example, if you are using Guile v2.2, and have Guile packages in the +`/usr/local` prefix, either add the following lines to your `.profile` or +`.bash_profile` so that the environment variable is properly set for all future +shell logins, or paste the lines into a POSIX-style shell to temporarily modify +the environment variables of your current shell session. + +```sh +# Help Guile v2.2.x find packages in /usr/local +export GUILE_LOAD_PATH="/usr/local/share/guile/site/2.2${GUILE_LOAD_PATH:+:}$GUILE_LOAD_PATH" +export GUILE_LOAD_COMPILED_PATH="/usr/local/lib/guile/2.2/site-ccache${GUILE_LOAD_COMPILED_PATH:+:}$GUILE_COMPILED_LOAD_PATH" +``` + +Note that these environment variables are used to check for packages during +`./configure`, so they should be set as soon as possible should you want to use +a prefix other than `/usr`. + +#### Building and installing source-built packages + +***IMPORTANT**: A few dependencies have non-obvious quirks/errata which are +documented in the sub-sections immediately below. Please read these sections +before proceeding to build and install these packages.* + +Although you should always refer to the README or INSTALL files for the most +accurate information, most of these dependencies use autoconf-style build +systems (check if there's a `configure.ac` file), and will likely do the right +thing with the following: + +Clone the repository and check out the latest release: +```sh +git clone <git-repo-of-dependency>/<dependency>.git +cd <dependency> +git tag -l # check for the latest release +git checkout <latest-release> +``` + +For autoconf-based build systems (if `./autogen.sh` or `configure.ac` exists at +the root of the repository): + +```sh +./autogen.sh || autoreconf -vfi +./configure --prefix=<prefix> +make +sudo make install +``` + +For CMake-based build systems (if `CMakeLists.txt` exists at the root of the +repository): + +```sh +mkdir build && cd build +cmake .. -DCMAKE_INSTALL_PREFIX=<prefix> +sudo cmake --build . --target install +``` + +If you choose not to specify exactly `--prefix=/usr` to `./configure`, please +make sure you've carefully read the [previous section] on mixing distribution +packages and source-built packages. + +##### Binding packages require `-dev`-suffixed packages + +Relevant for: +- Everyone + +When building bindings, the `-dev`-suffixed version of the original package +needs to be installed. For example, building `Guile-zlib` on Debian-derived +distributions requires that `zlib1g-dev` is installed. + +When using bindings, the `-dev`-suffixed version of the original package still +needs to be installed. This is particularly problematic when distribution +packages are mispackaged like `guile-sqlite3` is in Ubuntu Focal such that +installing `guile-sqlite3` does not automatically install `libsqlite3-dev` as a +dependency. + +Below is a list of relevant Guile bindings and their corresponding `-dev` +packages in Debian at the time of writing. + +| Guile binding package | -dev Debian package | +|-----------------------|---------------------| +| guile-gcrypt | libgcrypt-dev | +| guile-git | libgit2-dev | +| guile-lzlib | liblz-dev | +| guile-ssh | libssh-dev | +| guile-sqlite3 | libsqlite3-dev | +| guile-zlib | zlib1g-dev | + +##### `guile-git` actually depends on `libgit2 >= 1.1` + +Relevant for: +- Those building `guile-git` from source against `libgit2 < 1.1` +- Those installing `guile-git` from their distribution where `guile-git` is + built against `libgit2 < 1.1` + +As of v0.4.0, `guile-git` claims to only require `libgit2 >= 0.28.0`, however, +it actually requires `libgit2 >= 1.1`, otherwise, it will be confused by a +reference of `origin/keyring`: instead of interpreting the reference as "the +'keyring' branch of the 'origin' remote", the reference is interpreted as "the +branch literally named 'origin/keyring'" + +This is especially notable because Ubuntu Focal packages `libgit2 v0.28.4`, and +`guile-git` is built against it. + +Should you be in this situation, you need to build both `libgit2 v1.1.x` and +`guile-git` from source. + +Source: http://logs.guix.gnu.org/guix/2020-11-12.log#232527 + +##### `{scheme,guile}-bytestructures` v1.0.8 and v1.0.9 are broken for Guile v2.2 + +Relevant for: +- Those building `{scheme,guile}-bytestructures` from source against Guile v2.2 + +Commit +[707eea3](https://github.com/TaylanUB/scheme-bytestructures/commit/707eea3a85e1e375e86702229ebf73d496377669) +introduced a regression for Guile v2.2 and was first included in v1.0.8, this +was later corrected in commit +[ec9a721](https://github.com/TaylanUB/scheme-bytestructures/commit/ec9a721957c17bcda13148f8faa5f06934431ff7) +and included in v1.1.0. + +TL;DR If you decided to use Guile v2.2, do not use `{scheme,guile}-bytestructures` v1.0.8 or v1.0.9. + +### Building and Installing Guix itself + +Start by cloning Guix: + +``` +git clone https://git.savannah.gnu.org/git/guix.git +cd guix +``` + +You will likely want to build the latest release, however, if the latest release +when you're reading this is still 1.2.0 then you may want to use 95aca29 instead +to avoid a problem in the GnuTLS test suite. + +``` +git branch -a -l 'origin/version-*' # check for the latest release +git checkout <latest-release> +``` + +Bootstrap the build system: +``` +./bootstrap +``` + +Configure with the recommended `--localstatedir` flag: +``` +./configure --localstatedir=/var +``` + +Note: If you intend to hack on Guix in the future, you will need to supply the +same `--localstatedir=` flag for all future Guix `./configure` invocations.

More information on standard Automake directory variables +can be found +[here](https://www.gnu.org/software/automake/manual/html_node/Standard-Directory-Variables.html). + +However, the Guix init scripts and service configurations for Upstart, systemd, +SysV, and OpenRC are installed (in `${libdir}`) to launch +`${localstatedir}/guix/profiles/per-user/root/current-guix/bin/guix-daemon`, +which does not yet exist, and will only exist after [`root` performs their first +`guix pull`](#guix-pull-as-root). + +We need to create a `-original` version of these init scripts that's pointed to +the binaries we just built and `make install`'ed in `${bindir}` (normally, +`/usr/local/bin`). + +Example for `systemd`, run as `root`: + +```sh +# Create guix-daemon-original.service by modifying guix-daemon.service +libdir=# set according to your PREFIX (default is /usr/local/lib) +bindir="$(dirname $(command -v guix-daemon))" +sed -E -e "s|/\S*/guix/profiles/per-user/root/current-guix/bin/guix-daemon|${bindir}/guix-daemon|" "${libdir}"/systemd/system/guix-daemon.service > /etc/systemd/system/guix-daemon-original.service +chmod 664 /etc/systemd/system/guix-daemon-original.service + +# Make systemd recognize the new service +systemctl daemon-reload + +# Make sure that the non-working guix-daemon.service is stopped and disabled +systemctl stop guix-daemon +systemctl disable guix-daemon + +# Make sure that the working guix-daemon-original.service is started and enabled +systemctl enable guix-daemon-original +systemctl start guix-daemon-original +``` + +#### Creating `guix-daemon` users / groups + +Please see the [relevant +section](https://guix.gnu.org/manual/en/html_node/Build-Environment-Setup.html) +in the Guix Reference Manual for more details. + +## Optional setup + +At this point, you are set up to [use Guix to build Bitcoin +Core](./README.md#usage). However, if you want to polish your setup a bit and +make it "what Guix intended", then read the next few subsections. + +### Add an `/etc/profile.d` entry + +This section definitely does not apply to you if you installed Guix using: +1. The shell installer script +2. fanquake's Docker image +3. Debian's `guix` package + +#### Background + +Although Guix knows how to update itself and its packages, it does so in a +non-invasive way (it does not modify `/usr/local/bin/guix`). + +Instead, it does the following: + +- After a `guix pull`, it updates + `/var/guix/profiles/per-user/$USER/current-guix`, and creates a symlink + targeting this directory at `$HOME/.config/guix/current` + +- After a `guix install`, it updates + `/var/guix/profiles/per-user/$USER/guix-profile`, and creates a symlink + targeting this directory at `$HOME/.guix-profile` + +Therefore, in order for these operations to affect your shell/desktop sessions +(and for the principle of least astonishment to hold), their corresponding +directories have to be added to well-known environment variables like `$PATH`, +`$INFOPATH`, `$XDG_DATA_DIRS`, etc. + +In other words, if `$HOME/.config/guix/current/bin` does not exist in your +`$PATH`, a `guix pull` will have no effect on what `guix` you are using. Same +goes for `$HOME/.guix-profile/bin`, `guix install`, and installed packages. + +Helpfully, after a `guix pull` or `guix install`, a message will be printed like +so: + +``` +hint: Consider setting the necessary environment variables by running: + + GUIX_PROFILE="$HOME/.guix-profile" + . "$GUIX_PROFILE/etc/profile" + +Alternately, see `guix package --search-paths -p "$HOME/.guix-profile"'. +``` + +However, this is somewhat tedious to do for both `guix pull` and `guix install` +for each user on the system that wants to properly use `guix`. I recommend that +you instead add an entry to `/etc/profile.d` instead. This is done by default +when installing the Debian package later than 1.2.0-4 and when using the shell +script installer. + +#### Instructions + +Create `/etc/profile.d/guix.sh` with the following content: +```sh +# _GUIX_PROFILE: `guix pull` profile +_GUIX_PROFILE="$HOME/.config/guix/current" +if [ -L $_GUIX_PROFILE ]; then + export PATH="$_GUIX_PROFILE/bin${PATH:+:}$PATH" + # Export INFOPATH so that the updated info pages can be found + # and read by both /usr/bin/info and/or $GUIX_PROFILE/bin/info + # When INFOPATH is unset, add a trailing colon so that Emacs + # searches 'Info-default-directory-list'. + export INFOPATH="$_GUIX_PROFILE/share/info:$INFOPATH" +fi + +# GUIX_PROFILE: User's default profile +GUIX_PROFILE="$HOME/.guix-profile" +[ -L $GUIX_PROFILE ] || return +GUIX_LOCPATH="$GUIX_PROFILE/lib/locale" +export GUIX_PROFILE GUIX_LOCPATH + +[ -f "$GUIX_PROFILE/etc/profile" ] && .

Therefore, we need to +perform a `guix pull` as `root`: + +```sh +sudo --login guix pull --branch=version-<latest-release-version> +# or +sudo --login guix pull --commit=<particular-commit> +``` + +`guix pull` is quite a long process (especially if you're using +`--no-substitute`). If you encounter build problems, please refer to the +[troubleshooting section](#troubleshooting). + +Note that running a bare `guix pull` with no commit or branch specified will +pull the latest commit on Guix's master branch, which is likely fine, but not +recommended. + +If you installed Guix from source, you may get an error like the following: +```sh +error: while creating symlink '/root/.config/guix/current' No such file or directory +``` +To resolve this, simply: +``` +sudo mkdir -p /root/.config/guix +``` +Then try the `guix pull` command again. + +After the `guix pull` finishes successfully, +`${localstatedir}/guix/profiles/per-user/root/current-guix` should be populated. + +#### Using the newly-pulled `guix` by restarting the daemon + +Depending on how you installed Guix, you should now make sure that your init +scripts and service configurations point to the newly-pulled `guix-daemon`. + +##### If you built Guix from source + +If you followed the instructions for [fixing argv\[0\]][fix-argv0], you can now +do the following: + +```sh +systemctl stop guix-daemon-original +systemctl disable guix-daemon-original + +systemctl enable guix-daemon +systemctl start guix-daemon +``` + +##### If you installed Guix via the Debian/Ubuntu distribution packages + +You will need to create a `guix-daemon-latest` service which points to the new +`guix` rather than a pinned one. + +```sh +# Create guix-daemon-latest.service by modifying guix-daemon.service +sed -E -e "s|/usr/bin/guix-daemon|/var/guix/profiles/per-user/root/current-guix/bin/guix-daemon|" /etc/systemd/system/guix-daemon.service > /lib/systemd/system/guix-daemon-latest.service +chmod 664 /lib/systemd/system/guix-daemon-latest.service + +# Make systemd recognize the new service +systemctl daemon-reload + +# Make sure that the old guix-daemon.service is stopped and disabled +systemctl stop guix-daemon +systemctl disable guix-daemon + +# Make sure that the new guix-daemon-latest.service is started and enabled +systemctl enable guix-daemon-latest +systemctl start guix-daemon-latest +``` + +##### If you installed Guix via lantw44's Arch Linux AUR package + +At the time of writing (July 5th, 2021) the systemd unit for "updated Guix" is +`guix-daemon-latest.service`, therefore, you should do the following: + +```sh +systemctl stop guix-daemon +systemctl disable guix-daemon + +systemctl enable guix-daemon-latest +systemctl start guix-daemon-latest +``` + +##### Otherwise... + +Simply do: + +```sh +systemctl restart guix-daemon +``` + +### Checking everything + +If you followed all the steps above to make your Guix setup "prim and proper," +you can check that you did everything properly by running through this +checklist. + +1. `/etc/profile.d/guix.sh` should exist and be sourced at each shell login + +2. `guix describe` should not print `guix describe: error: failed to determine + origin`, but rather something like: + + ``` + Generation 38 Feb 22 2021 16:39:31 (current) + guix f350df4 + repository URL: https://git.savannah.gnu.org/git/guix.git + branch: version-1.2.0 + commit: f350df405fbcd5b9e27e6b6aa500da7f101f41e7 + ``` + +3. `guix-daemon` should be running from `${localstatedir}/guix/profiles/per-user/root/current-guix` + +# Troubleshooting + +## Derivation failed to build + +When you see a build failure like below: + +``` +building /gnu/store/...-foo-3.6.12.drv... +/ 'check' phasenote: keeping build directory `/tmp/guix-build-foo-3.6.12.drv-0' +builder for `/gnu/store/...-foo-3.6.12.drv' failed with exit code 1 +build of /gnu/store/...-foo-3.6.12.drv failed +View build log at '/var/log/guix/drvs/../...-foo-3.6.12.drv.bz2'. +cannot build derivation `/gnu/store/...-qux-7.69.1.drv': 1 dependencies couldn't be built +cannot build derivation `/gnu/store/...-bar-3.16.5.drv': 1 dependencies couldn't be built +cannot build derivation `/gnu/store/...-baz-2.0.5.drv': 1 dependencies couldn't be built +guix time-machine: error: build of `/gnu/store/...-baz-2.0.5.drv' failed +``` + +It means that `guix` failed to build a package named `foo`, which was a +dependency of `qux`, `bar`, and `baz`.

However, there are ways to work around this issue: + +#### Workaround 1: Using substitutes for this single derivation + +If you've authorized the official Guix build farm's key (more info +[here](./README.md#step-1-authorize-the-signing-keys)), then you can use +substitutes just for this single derivation by invoking the following: + +```sh +guix build --substitute-urls="https://ci.guix.gnu.org" /gnu/store/vhphki5sg9xkdhh2pbc8gi6vhpfzryf0-gnutls-3.6.12.drv +``` + +See [this section](./README.md#removing-authorized-keys) for instructions on how +to remove authorized keys if you don't want to keep the build farm's key +authorized. + +#### Workaround 2: Temporarily setting the system clock back + +This workaround was described [here](https://issues.guix.gnu.org/44559#5). + +Basically: +1.
