Configure & Build Cantera¶
These directions are for the development version of Cantera. For the current release, see these instructions.
Determine configuration options¶
scons helpto see a list of all of the configuration options for Cantera, or see all of the options on the Configuration Options page.
Configuration options are specified as additional arguments to the
sconscommand. For example:
sconsis the program that manages the build steps, and
commandis most commonly one of
Other commands are possible, and are explained in the Build Commands section.
SCons saves configuration options specified on the command line in the file
cantera.confin the root directory of the source tree, so generally it is not necessary to respecify configuration options when rebuilding Cantera. To unset a previously set configuration option, either remove the corresponding line from
cantera.confor use the syntax:
Sometimes, changes in your environment can cause SCons’s configuration tests (for example, checking for libraries or compiler capabilities) to unexpectedly fail. To force SCons to re-run these tests rather than trusting the cached results, run scons with the option
The following lists of options are not complete, they show only some commonly used options. The entire list of options can be found on the Configuration options page.
Python Module Options¶
Compiling the Cantera Python module requires that NumPy and Cython are installed for the target installation of Python. The following SCons options control how the Python module is built:
By default, SCons will try to build the full Python interface for copy of Python that is running SCons. Use this option if you wish to build Cantera for a different Python installation.
For backwards compatibility, the following options are also allowed, but are overridden by the above options. These options will be removed in a future version of Cantera:
Windows Only Options¶
cantera.conf file uses the backslash character
\ as an escape
character. When modifying this file, backslashes in paths need to be escaped
boost_inc_dir = 'C:\\Program Files (x86)\\boost\\include'
This does not apply to paths specified on the command line. Alternatively,
you can use forward slashes (
/) in paths.
In Windows there aren’t any proper default locations for many of the packages that Cantera depends on, so you will need to specify these paths explicitly.
Remember to put double quotes around any paths with spaces in them, such as
By default, SCons attempts to use the same architecture as the copy of Python that is running SCons, and the most recent installed version of the Visual Studio compiler. If you aren’t building the Python module, you can override this with the configuration options
To compile with MinGW, specify the toolchain option:
MATLAB Toolbox Options¶
Building the MATLAB toolbox requires an installed copy of MATLAB, and the path to the directory where MATLAB is installed must be specified using the following option:
Fortran Module Options¶
Building the Fortran module requires a compatible Fortran comiler. SCons will
attempt to find a compatible compiler by default in the
variable. The following options control how the Fortran module is built:
The following options control if the documentation is built:
The following options are possible as commands to SCons (that is, the first
Print a description of user-specifiable options.
Compile Cantera and the language interfaces using default options.
Delete files created while building Cantera.
[sudo] scons install
[sudo] scons uninstall
Run all tests which did not previously pass or for which the results may have changed.
Reset the passing status of all tests.
Delete files created while running the tests.
List available tests.
Run the test named
scons <command> dump
Dump the state of the SCons environment to the screen instead of doing
<command>, for example,
scons build dump. For debugging purposes.
Compile the C++ and Fortran samples.
Build a Windows installer (.msi) for Cantera.
Build the Sphinx documentation
Build the Doxygen documentation
Compile Cantera & Test¶
Run SCons with the list of desired configuration options:
If Cantera compiles successfully, you should see a message that looks like:
******************************************************* Compilation completed successfully. - To run the test suite, type 'scons test'. - To install, type '[sudo] scons install'. *******************************************************
If you do not see this message, check the output for errors to see what went wrong.
Cantera has a series of tests that can be run with the command:
When the tests finish, you should see a summary indicating the number of tests that passed and failed.
If you have tests that fail, try looking at the following to determine the source of the error:
Messages printed to the console while running
Output files generated by the tests
