Chapter 1. Red Hat Developer Toolset

1.1. About Red Hat Developer Toolset

Red Hat Developer Toolset is a Red Hat offering for developers on the Red Hat Enterprise Linux platform, and provides a complete set of development and performance analysis tools that can be installed and used on multiple versions of Red Hat Enterprise Linux. Executables built with the Red Hat Developer Toolset toolchain can then also be deployed and run on multiple versions of Red Hat Enterprise Linux. For detailed compatibility information, see Section 1.3, “Compatibility”.
Red Hat Developer Toolset does not replace the default system tools provided with Red Hat Enterprise Linux 5 or 6 when installed on those platforms. Instead, a parallel set of developer tools provides an alternative, newer version of those tools for optional use by developers. The default compiler and debugger, for example, remain those provided by the base Red Hat Enterprise Linux system.

memstomp 0.1.4 Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 A debugging tool to identify calls to library functions with overlapping memory regions that are not allowed by various standards.
SystemTap 2.1 Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 A tracing and probing tool to monitor the activities of the entire system without the need to instrument, recompile, install, and reboot.
Valgrind 3.8.1 Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 An instrumentation framework and a number of tools to profile applications in order to detect memory errors, identify memory management problems, and report any use of improper arguments in system calls.
OProfile 0.9.8 Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 A system-wide profiler that uses the performance monitoring hardware on the processor to retrieve information about the kernel and executables on the system.
Dyninst 8.0 Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6 A library for instrumenting and working with user-space executables during their execution.
[a] If you intend to develop applications for Red Hat JBoss Middleware or require support for OpenShift Tools, it is recommended that you use Red Hat JBoss Developer Studio.

Red Hat Developer Toolset differs from Technology Preview compiler releases previously supplied in Red Hat Enterprise Linux in two important respects:
  1. Red Hat Developer Toolset can be used on multiple major and minor releases of Red Hat Enterprise Linux, as detailed in Section 1.3, “Compatibility”.
  2. Unlike Technology Preview compilers and other tools shipped in earlier Red Hat Enterprise Linux, Red Hat Developer Toolset is fully supported under Red Hat Enterprise Linux Subscription Level Agreements, is functionally complete, and is intended for production use.
Important bug fixes and security errata are issued to Red Hat Developer Toolset subscribers in a similar manner to Red Hat Enterprise Linux for two years from the release of each major version release. A new major version of Red Hat Developer Toolset is released annually, providing significant updates for existing components and adding major new components. A single minor release, issued six months after each new major version release, provides a smaller update of bug fixes, security errata, and new minor components.
Additionally, the Red Hat Enterprise Linux Application Compatibility Specification also applies to Red Hat Developer Toolset (subject to some constraints on the use of newer C++11 language features, detailed in Section B.2.2.3, “ABI Compatibility”).


Applications and libraries provided by Red Hat Developer Toolset do not replace the Red Hat Enterprise Linux system versions, nor are they used in preference to the system versions. Using a framework called Software Collections, an additional set of developer tools is installed into the /opt directory and is explicitly enabled by the user on demand using the supplied scl utility.
