ecosconfig: eCos configuration program


ecosconfig -- eCos configuration program


ecosconfig [--help ] [--config=file] [--prefix=dir] [--srcdir=dir] [--no-resolve] [--ignore-errors | -i ] [--verbose | -v ] [-q] command


This manual page documents briefly the ecosconfig command. This manual page was written for the Debian distribution because the original program does not have a manual page. Instead, it has documentation in the PDF format; see below. ecosconfig is a program to configure your eCos kernel linked with your embedded application and creating the build tree.
This program follows the usual GNU command line syntax, with long options starting with two dashes ('-'). A summary of options is included below. For a complete description, see the PDF files. -h --help Provides basic usage guidelines for the available commands and qualifiers. All other qualifiers and commands are ignored if --help is used. --config=file Specifies an eCos configuration save file for use by the tool. By default, the file ecos.ecc in the current directory is used. Developers may prefer to use a common location for all their eCos configurations rather than keep the configuration information in the base of the build tree. --prefix=dir Specifies an alternative location for the install tree. By default, the install tree resides inside the install directory in the build tree. Developers may prefer to locate the build tree in a temporary file hierarchy but keep the install tree in a more permanent location. --srcdir=dir Specifies the location of the component repository. By default, the tool uses the location specified in the ECOS_REPOSITORY environment variable. Developers may prefer to use of this qualifier if they are working with more than one repository. --no-resolve Disables the implicit resolution of conflicts while manipulating the configuration data. developers may prefer to reslove conflicts by editing the eCos configuration save file manually The check command implicitely uses --no-resolve. --ignore-errors -i By default, ecosconfig will exit with an error code if the current configuration contains any conflicts, and it is not possible to generate or update a build tree for such configurations. This qualifier causes ecosconfig to ignore such problems, and hence it is possible to generate a build tree even if there are still conflicts. Of course, there are no guarantees that the resulting system will actually do anything useful. -v --verbose Display more information. -q Display less information.
The available commands for ecosconfig are as follows: list Lists the available packages, targets and templates as installed in the eCos repository. Aliases and package versions are also reported. new target [template [version]] Creates a new eCos configuration for the specified target hardware and saves it. A software template may also be specified. By default, the template named 'default' is used. If the template version is not specified, the latest version is used. target target Changes the target hardware selection for the eCos configuration. This has the effect of unloading packages supporting the target selected previously and loading the packages which support the new hardware. This command will be used typically when switching between a simulator and real hardware. template template [version] Changes the template selection for the eCos configuration. This has the effect of unloading packages specified by the template selected previously and loading the packages specified by the new template. By default, the latest version of the specified template is used. remove packages Removes the specified packages from the eCos configuration. This command will be used typically when the template on which a configuration is based contains packages which are not required. add packages Adds the specified packages to the eCos configuration. This command will be used typically when the template on which a configuration is based does not contain all the packages which are required. For example, add-on packages provided by third parties will not be known to the standard templates so they will have to be added explicitely. version version packages Selects the specified version of a number of packages in the eCos configuration. By default, the most recent version of each package is used. This command will be used typically when an older version of a package is required. check Presents the following information concerning the current configuration: 0. the selected target hardware 1. the selected template 2. additional packages 3. removed packages 4. the selected version of packages where this is not the most recent version 5. conflicts in the current configuration The check command will never perform automatic conflict resolution, so there is no need to use --no-resolve. resolve Resolves conflicts identified in the current eCos configuration by invoking an inference capability. Resolved conflicts are reported, but not all conflicts may be resolvable. This command will be used typically following manual editing of the configuration. export file Exports a minimal eCos configurastion save file with the specified name. This file contains only those options which do not have their default value. Such files are used typically to transfer option values from one configuration to another. import file Imports a minimal eCos configuration save file with the specified name. The values of those options specified in the file are applied to the current configuration.


The programs are documented fully by eCos User's Guide available.
