GNU Toolchain Open-source tools for real-time system programming with LynxOS

The LynuxWorks™ Open Development Environment (ODE) includes a variety of open-source tools and utilities, including many derived from the Free Software Foundation's GNU family. LynuxWorks open-source tool offerings include:

• Compile and debug tools
• Revision Control System
• Shells
• Text editors
• Other utilities

GNU compilation and debugging tools

LynuxWorks ODE distributions for both cross and LynxOS® native configurations include releases of the industry-standard gcc (v. 3.4.3) and g++ ANSI C and C++ compilers, as well as the gas assembler, for the processor family addressed by the tool kit (e.g., PowerPC®).

Also available for LynxOS is the GNAT Pro Ada 95 Development Environment from Adacore, which is based on mature GNU/GCC technology.

In the ODE, LynuxWorks also includes a LynxOS-integrated version of the popular gdb source-level debugger, TotalDB (v. 6.5). To meet the challenge of debugging embedded and real-time applications, LynuxWorks has extended gdb capabilities in TotalDB to include:

• Multi-threaded applications debugging:
  • LynxOS thread ID display
  • Thread context switching
  • Thread-specific breakpoints
• System and device driver debug via integration with the LynuxWorks skdb Simple Kernel Debugger
• Remote network and serial target connections
• Cross-hosted and LynxOS native debugging
• Optional INSIGHT graphical debugger user interface

GNU versions

LynuxWorks produces LynxOS-targeted and -optimized versions of the GNU compilers and debuggers. The LynuxWorks releases represent extremely stable versions of the GNU technology and are backed by LynuxWorks' award-winning technical support.

Revision Control System (GNU RCS)

The LynuxWorks ODE includes the industry-standard RCS Revision Control System. RCS simplifies the maintenance of large software projects. RCS supports checking in and out of project source code to and from different branches of a tree. RCS branches can also be locked to provide mutually exclusive access for different parts of a development team.

Shells

The LynxOS real-time operating system, even when deployed in deeply embedded configurations, is robust and sufficiently rich in APIs that it can easily support standard command shell interfaces. Various open-source shells are provided with the ODE, for either native development or deployed system command interfaces:

Text editors

The LynuxWorks ODE includes several text editors for general purpose use by software developers:

vi
The vi and ex text editors are included as the default supported editing tools for LynxOS native/hosted development. The ODE supports standard terminal types and under the native ODE X/Motif PosixWorks environment also supports built-in x-terms.

GNU Emacs
GNU Emacs is a popular and very sophisticated text and program editor with numerous features targeted for software development.

Other utilities

Many the popular GNU and other open-source utilities are included as a standard part of the LynxOS Open Development Environment. Examples include:

bc, bison, byacc, c++filter, cmp, cpio, diff, expect, fgrep, flex, gawk, gprof, grep, indent, info, make, nm, path, ranlib, runtest, sed and xargs.
