The command-line options presented below are specific to guix
build
.
--quiet
-q
Build quietly, without displaying the build log; this is equivalent to --verbosity=0. Upon completion, the build log is kept in /var (or similar) and can always be retrieved using the --log-file option.
--file=file
-f arquivo
Build the package, derivation, or other file-like object that the code within file evaluates to (see file-like objects).
As an example, file might contain a package definition like this (see Definindo pacotes):
(use-modules (guix) (guix build-system gnu) (guix licenses)) (package (name "hello") (version "2.10") (source (origin (method url-fetch) (uri (string-append "mirror://gnu/hello/hello-" version ".tar.gz")) (sha256 (base32 "0ssi1wpaf7plaswqqjwigppsg5fyh99vdlb9kzl7c9lng89ndq1i")))) (build-system gnu-build-system) (synopsis "Hello, GNU world: An example GNU package") (description "Guess what GNU Hello prints!") (home-page "http://www.gnu.org/software/hello/") (license gpl3+))
The file may also contain a JSON representation of one or more package
definitions. Running guix build -f
on hello.json with the
following contents would result in building the packages myhello
and
greeter
:
[ { "name": "myhello", "version": "2.10", "source": "mirror://gnu/hello/hello-2.10.tar.gz", "build-system": "gnu", "arguments": { "tests?": false } "home-page": "https://www.gnu.org/software/hello/", "synopsis": "Hello, GNU world: An example GNU package", "description": "GNU Hello prints a greeting.", "license": "GPL-3.0+", "native-inputs": ["gettext"] }, { "name": "greeter", "version": "1.0", "source": "https://example.com/greeter-1.0.tar.gz", "build-system": "gnu", "arguments": { "test-target": "foo", "parallel-build?": false, }, "home-page": "https://example.com/", "synopsis": "Greeter using GNU Hello", "description": "This is a wrapper around GNU Hello.", "license": "GPL-3.0+", "inputs": ["myhello", "hello"] } ]
--manifest=manifest
-m manifest
Build all packages listed in the given manifest (see --manifest).
--expression=expr
-e expr
Build the package or derivation expr evaluates to.
For example, expr may be (@ (gnu packages guile) guile-1.8)
,
which unambiguously designates this specific variant of version 1.8 of
Guile.
Alternatively, expr may be a G-expression, in which case it is used as
a build program passed to gexp->derivation
(see Expressões-G).
Lastly, expr may refer to a zero-argument monadic procedure
(see A mônada do armazém). The procedure must return a derivation as a
monadic value, which is then passed through run-with-store
.
--source
-S
Build the source derivations of the packages, rather than the packages themselves.
For instance, guix build -S gcc
returns something like
/gnu/store/…-gcc-4.7.2.tar.bz2, which is the GCC source
tarball.
The returned source tarball is the result of applying any patches and code
snippets specified in the package origin
(see Definindo pacotes).
As with other derivations, the result of building a source derivation can be verified using the --check option (see build-check). This is useful to validate that a (potentially already built or substituted, thus cached) package source matches against its declared hash.
Note that guix build -S
compiles the sources only of the specified
packages. They do not include the sources of statically linked dependencies
and by themselves are insufficient for reproducing the packages.
--sources
Fetch and return the source of package-or-derivation and all their dependencies, recursively. This is a handy way to obtain a local copy of all the source code needed to build packages, allowing you to eventually build them even without network access. It is an extension of the --source option and can accept one of the following optional argument values:
package
This value causes the --sources option to behave in the same way as the --source option.
all
Build the source derivations of all packages, including any source that
might be listed as inputs
. This is the default value.
$ guix build --sources tzdata The following derivations will be built: /gnu/store/…-tzdata2015b.tar.gz.drv /gnu/store/…-tzcode2015b.tar.gz.drv
transitive
Build the source derivations of all packages, as well of all transitive inputs to the packages. This can be used e.g. to prefetch package source for later offline building.
$ guix build --sources=transitive tzdata The following derivations will be built: /gnu/store/…-tzcode2015b.tar.gz.drv /gnu/store/…-findutils-4.4.2.tar.xz.drv /gnu/store/…-grep-2.21.tar.xz.drv /gnu/store/…-coreutils-8.23.tar.xz.drv /gnu/store/…-make-4.1.tar.xz.drv /gnu/store/…-bash-4.3.tar.xz.drv …
--system=system
-s sistema
Attempt to build for system—e.g., i686-linux
—instead of the
system type of the build host. The guix build
command allows you
to repeat this option several times, in which case it builds for all the
specified systems; other commands ignore extraneous -s options.
Nota: The --system flag is for native compilation and must not be confused with cross-compilation. See --target below for information on cross-compilation.
An example use of this is on Linux-based systems, which can emulate
different personalities. For instance, passing --system=i686-linux
on an x86_64-linux
system or --system=armhf-linux on an
aarch64-linux
system allows you to build packages in a complete
32-bit environment.
Nota: Building for an
armhf-linux
system is unconditionally enabled onaarch64-linux
machines, although certain aarch64 chipsets do not allow for this functionality, notably the ThunderX.
Similarly, when transparent emulation with QEMU and binfmt_misc
is
enabled (see qemu-binfmt-service-type
),
you can build for any system for which a QEMU binfmt_misc
handler is
installed.
Builds for a system other than that of the machine you are using can also be offloaded to a remote machine of the right architecture. See Usando o recurso de descarregamento, for more information on offloading.
--target=triplet
¶Cross-build for triplet, which must be a valid GNU triplet, such as
"aarch64-linux-gnu"
(see GNU
configuration triplets in Autoconf).
--list-systems
List all the supported systems, that can be passed as an argument to --system.
--list-targets
List all the supported targets, that can be passed as an argument to --target.
--check
¶Rebuild package-or-derivation, which are already available in the store, and raise an error if the build results are not bit-for-bit identical.
This mechanism allows you to check whether previously installed substitutes
are genuine (see Substitutos), or whether the build result of a package
is deterministic. See Invocando guix challenge
, for more background
information and tools.
Quando usado em conjunto com --keep-failed, uma saída de comparação é mantida no armazém, sob /gnu/store/…-check. Isso facilita procurar por diferenças entre os dois resultados.
--repair
¶Attempt to repair the specified store items, if they are corrupt, by re-downloading or rebuilding them.
This operation is not atomic and thus restricted to root
.
--derivations
-d
Return the derivation paths, not the output paths, of the given packages.
--root=arquivo
¶-r arquivo
Make file a symlink to the result, and register it as a garbage collector root.
Consequently, the results of this guix build
invocation are
protected from garbage collection until file is removed. When that
option is omitted, build results are eligible for garbage collection as soon
as the build completes. See Invocando guix gc
, for more on GC roots.
--log-file
¶Return the build log file names or URLs for the given package-or-derivation, or raise an error if build logs are missing.
This works regardless of how packages or derivations are specified. For instance, the following invocations are equivalent:
guix build --log-file $(guix build -d guile) guix build --log-file $(guix build guile) guix build --log-file guile guix build --log-file -e '(@ (gnu packages guile) guile-2.0)'
If a log is unavailable locally, and unless --no-substitutes is passed, the command looks for a corresponding log on one of the substitute servers (as specified with --substitute-urls).
So for instance, imagine you want to see the build log of GDB on
aarch64
, but you are actually on an x86_64
machine:
$ guix build --log-file gdb -s aarch64-linux https://ci.guix.gnu.org/log/…-gdb-7.10
You can freely access a huge library of build logs!
