Chapter 21. Building

When you have configured eCos, you may build the configuration.

On the Build menu, click:

• Library (or click the Build Library icon on the toolbar) – this causes the eCos configuration to be built. The result of a successful build will be (among other things) a library against which user code can be linked

• Tests – this causes the eCos configuration to be built, and additionally builds the relevant test cases linked against the eCos library

• Clean – this removes all intermediate files, thus causing a subsequent build/library or build/tests operation to cause recompilation of all relevant files.

• Stop – this causes a currently executing build (any of the above steps) to be interrupted

Build options may be displayed by using the Build->Options menu item. This displays a dialog box containing a drop-list control and two windows. The drop-list control allows you to select the type of build option to be displayed (for example “LDFLAGS” are the options applied at link-time. The left-hand window is a tree view of the packages loaded in the current configuration. The right-hand window is a list of the build options that will be used for the currently selected package.

Note that this dialog box currently affords only read-only access to the build options. In order to change build options you must edit the relevant string configuration item.

A single level of inheritance is supported: each package’s build options are combined with the global options (these are to be found in the “Global build options” folder in the configuration view).
