Global options

--arch=ARCHITECTURE

By default, Nitrile will detect the current platform and architecture and build for this target. --arch allows you to pretend to be a different target.

This is for example useful to build a 32-bit application on a 64-bit platform.

It can also be used to package libraries for entirely different targets (e.g., create an ARM distribution on an Intel machine) when there are no build steps, i.e. when packaging just involves collecting files.

Possible values of ARCHITECTURE are:

  • arm64
  • x64
  • x86
  • any (when the architecture and bitwidth do not matter)

The following values can be used when the architecture matters but the bitwidth does not matter:

  • arm
  • intel

The following values can be used when the bitwidth matters but the architecture does not matter:

  • 32bit
  • 64bit

--clm-linker=LINKER

Use LINKER to link the application in clm jobs. For the possible values of LINKER, see the gcc documentation on -fuse-ld. Use --clm-linker=ld to use the default linker.

A default can be set for this option in nitrile-settings.yml.

--local-dependency DEP PATH

This option is useful when developing multiple packages at once. For example, you are fixing a bug in package current for which some changes in a dependency dep are needed. You can then clone the repository for dep elsewhere, and use --local-dependency dep path/to/dep when running nitrile build or nitrile test in the current package.

PATH/nitrile.yml must exist. The dependencies of the current package and those of DEP are combined. The constraint solver is invoked to find a set of packages from both the current package’s nitrile-packages and DEP‘s nitrile-packages. Thus, for each dependency, one of these sources is used (in descending order of preference):

  • The current package
  • A package specified with --local-dependency
  • A package installed in either the current package’s nitrile-packages, or in the nitrile-packages dir of a local dependency

Because --local-dependency uses special logic to resolve dependencies, it cannot be used with nitrile fetch.

Info

Use --verbose to see the sources used for all the dependencies.

Warning

For the time being --local-dependency has an impact on include paths only. It is not possible to use this option to point to a package from which an executable from bin or exe is needed.

Warning

Build steps of local dependencies are not taken into account. If your changes in the local dependencies require a nitrile build cycle (for example, if the dependency contains C sources to link with), you have to manually run nitrile build in the directory of the dependency.

--name=NAME

When nitrile.yml contains multiple packages, NAME specifies the package to use.

--no-header

Do not print copyright and license information. This can be useful in scripts. The license terms still apply.

--parallel-jobs=N

Use at most N parallel jobs in clm jobs in build and test scripts. N must be a positive integer and should not be higher than the number of available processors. By default, clm takes as many subprocesses as there are processors available.

A default can be set for this option in nitrile-settings.yml.

--platform=PLATFORM

This is like --arch, but allows you to specify a platform rather than an architecture. Possible values of PLATFORM are:

  • linux
  • mac
  • windows
  • any (when the platform does not matter)

--verbose

Enables verbose output.
