Host and Target Development Tools

The Sun Embedded Workshop provides a complete development environment for creating applications or systems that use the ChorusOS operating system (or an embedded system based on the ChorusOS operating system). The Sun Embedded Workshop contains the ChorusOS operating system and development environment. For a comprehensive overview of The Sun Embedded Workshop software, refer to "Multi-Platform Development Environment" in ChorusOS 5.0 Features and Architecture Overview.

Development Environment Components

The development environment provided by the Sun Embedded Workshop includes the following major components:

• C and C++ Development Toolchain, including the GNU gcc and g++ cross-compilers.

• A debugging framework and a C and C++ reference debugger, GNU GDB debugger for ChorusOS systems. The current version of GDB includes the Insight graphical user interface. For more information on the ChorusOS debugging tools, refer to the ChorusOS 5.0 Debugging Guide.

• A set of configuration tools.

• A set of libraries, described in "ChorusOS APIs".

Configuration Tools

The ChorusOS operating system consists of modules that can be configured by providing a list of the required components. The configuration tools manage any hidden dependencies or incompatibilities.

The configuration tools are designed to be flexible enough to configure system components and application actors that are part of the ChorusOS operating system image.

You can use the Ews graphical user interface or a command-line interface (configurator) to view or modify characteristics of a ChorusOS operating system image. In addition to selecting the components required for the operating system, Sun Embedded Workshop supports three other levels of system configuration:

• Resources. For the list of selected components, you can fix the amount of resources to be managed and set the values of tunable parameters, for example, the amount of memory reserved for network buffers.

• Boot actors. Additional actors can be included in the memory image loaded at boot time.

• Environment. System-wide configuration parameters can be fixed by setting environment strings, which are similar to the environment variables used in UNIX systems. The operating system and actors retrieve these environment strings when they are initialized.
