               [-s SETTINGS] [-u]
               path reference

Builds a binary package for a recipe ( 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 or to a
                        recipe file e.g., my_folder/
  reference             user/channel or pkg/version@user/channel (if name and
                        version not declared in where the
                        package will be created

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 local cache. Use
                        this for testing purposes only
  -kb, --keep-build     Do not remove the build folder in local cache. Use
                        this for testing purposes only
  -ne, --not-export     Do not export the
  -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
  -m [MANIFESTS], --manifests [MANIFESTS]
                        Install dependencies manifests in folder for later
                        verify. Default folder is .conan_manifests, but can be
                        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, use it to choose if you want to build from
                        sources: --build Build all from sources, do not use
                        binary packages. --build=never Never build, use binary
                        packages or fail if a binary package is not found.
                        --build=missing Build from code if a binary package is
                        not found. --build=outdated Build from code if the
                        binary is not built with the current recipe or when
                        missing binary package. --build=[pattern] Build always
                        these packages from source, but never build the
                        others. Allows multiple --build parameters. 'pattern'
                        is a fnmatch file pattern of a package name. Default
                        behavior: If you don't specify anything, it will be
                        similar to '--build=never', but package recipes can
                        override it with their 'build_policy' attribute in the
  -e ENV, --env ENV     Environment variables that will be set during the
                        package build, -e CXX=/usr/bin/clang++
  -o OPTIONS, --options OPTIONS
                        Define options values, e.g., -o Pkg:with_qt=true
  -pr PROFILE, --profile PROFILE
                        Apply the specified profile to the install command
  -r REMOTE, --remote REMOTE
                        Look in the specified remote server
  -s SETTINGS, --settings SETTINGS
                        Settings to build the package, overwriting the
                        defaults. e.g., -s compiler=gcc
  -u, --update          Check updates exist from upstream remotes

This is the recommended way to create packages.

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


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 in the following order:

  1. config_options()
  2. configure()
  3. requirements()
  4. package_id()
  5. build_requirements()
  6. build_id()
  7. system_requirements()
  8. source()
  9. imports()
  10. build()
  11. package()
  12. 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.
