path [reference]
Builds a binary package for a recipe (conanfile.py).
Uses the specified configuration in a profile or in -s settings, -o options, etc. If a ‘test_package’ folder (the name can be configured with -tf) is found, the command will run the consumer project to ensure that the package has been created correctly. Check ‘conan test’ command to know more about ‘test_folder’ project.
positional arguments:
path Path to a folder containing a conanfile.py or to a
recipe file e.g., my_folder/conanfile.py
reference user/channel, version@user/channel or
pkg/version@user/channel (if name or version declared
in conanfile.py, they should match)
optional arguments:
-h, --help show this help message and exit
-j JSON, --json JSON json file path where the install information will be
written to
-k, -ks, --keep-source
Do not remove the source folder in the local cache,
even if the recipe changed. Use this for testing
purposes only
-kb, --keep-build Do not remove the build folder in local cache. Implies
--keep-source. Use this for testing purposes only
-ne, --not-export Do not export the conanfile.py
-tbf TEST_BUILD_FOLDER, --test-build-folder TEST_BUILD_FOLDER
Working directory for the build of the test project.
-tf TEST_FOLDER, --test-folder TEST_FOLDER
Alternative test folder name. By default it is
"test_package". Use "None" to skip the test stage
--ignore-dirty When using the "scm" feature with "auto" values,
capture the revision and url even if there are
uncommitted changes
-m [MANIFESTS], --manifests [MANIFESTS]
Install dependencies manifests in folder for later
verify. Default folder is .conan_manifests, but can be
changed
-mi [MANIFESTS_INTERACTIVE], --manifests-interactive [MANIFESTS_INTERACTIVE]
Install dependencies manifests in folder for later
verify, asking user for confirmation. Default folder
is .conan_manifests, but can be changed
-v [VERIFY], --verify [VERIFY]
Verify dependencies manifests against stored ones
-b [BUILD], --build [BUILD]
Optional, specify which packages to build from source.
Combining multiple '--build' options on one command
line is allowed. For dependencies, the optional
'build_policy' attribute in their conanfile.py takes
precedence over the command line parameter. Possible
parameters: --build Force build for all packages, do
not use binary packages. --build=never Disallow build
for all packages, use binary packages or fail if a
binary package is not found. Cannot be combined with
other '--build' options. --build=missing Build
packages from source whose binary package is not
found. --build=outdated Build packages from source
whose binary package was not generated from the latest
recipe or is not found. --build=cascade Build packages
from source that have at least one dependency being
built from source. --build=[pattern] Build packages
from source whose package reference matches the
pattern. The pattern uses 'fnmatch' style wildcards.
Default behavior: If you omit the '--build' option,
the 'build_policy' attribute in conanfile.py will be
used if it exists, otherwise the behavior is like '--
build=package name'.
-r REMOTE, --remote REMOTE
Look in the specified remote server
-u, --update Check updates exist from upstream remotes
-l [LOCKFILE], --lockfile [LOCKFILE]
Path to a lockfile or folder containing 'conan.lock'
file. Lockfile can be updated if packages change
-e ENV_HOST, --env ENV_HOST
Environment variables that will be set during the
package build (host machine). e.g.: -e
CXX=/usr/bin/clang++
-e:b ENV_BUILD, --env:build ENV_BUILD
Environment variables that will be set during the
package build (build machine). e.g.: -e:b
CXX=/usr/bin/clang++
-e:h ENV_HOST, --env:host ENV_HOST
Environment variables that will be set during the
package build (host machine). e.g.: -e:h
CXX=/usr/bin/clang++
-o OPTIONS_HOST, --options OPTIONS_HOST
Define options values (host machine), e.g.: -o
Pkg:with_qt=true
-o:b OPTIONS_BUILD, --options:build OPTIONS_BUILD
Define options values (build machine), e.g.: -o:b
Pkg:with_qt=true
-o:h OPTIONS_HOST, --options:host OPTIONS_HOST
Define options values (host machine), e.g.: -o:h
Pkg:with_qt=true
-pr PROFILE_HOST, --profile PROFILE_HOST
Apply the specified profile to the host machine
-pr:b PROFILE_BUILD, --profile:build PROFILE_BUILD
Apply the specified profile to the build machine
-pr:h PROFILE_HOST, --profile:host PROFILE_HOST
Apply the specified profile to the host machine
-s SETTINGS_HOST, --settings SETTINGS_HOST
Settings to build the package, overwriting the
defaults (host machine). e.g.: -s compiler=gcc
-s:b SETTINGS_BUILD, --settings:build SETTINGS_BUILD
Settings to build the package, overwriting the
defaults (build machine). e.g.: -s:b compiler=gcc
-s:h SETTINGS_HOST, --settings:host SETTINGS_HOST
Settings to build the package, overwriting the
defaults (host machine). e.g.: -s:h compiler=gcc
conan create . demo/testing is equivalent to:
$ conan export . demo/testing
$ conan install hello/0.1@demo/testing --build=hello
# package is created now, use test to test it
$ cd test_package
$ conan test . hello/0.1@demo/testing
Tip
Sometimes you need to skip/disable test stage to avoid a failure while creating the package, i.e: when you are cross compiling libraries and target code cannot be executed in current host platform. In that case you can skip/disable the test package stage:
$ conan create . demo/testing --test-folder=None
conan create executes methods of a conanfile.py in the following order:
config_options()configure()requirements()package_id()build_requirements()build_id()system_requirements()source()imports()build()package()package_info()
In case of installing a pre-built binary, steps from 5 to 11 will be skipped. Note that deploy() method is only used in
conan install.
Note
Installation of binaries can be accelerated setting up parallel downloads with the general.parallel_download
experimental configuration in conan.conf.
