A Red Hat training course is available for Red Hat Developer Toolset
Chapter 1. System Requirements
This chapter specifies hardware requirements and contains information related to the installation of Red Hat Developer Toolset 4.0.
1.1. Installation Prerequisites
Red Hat Developer Toolset 4.0 contains packages for both Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7 running on AMD64 and Intel 64 architectures. Generation and manipulation of 32-bit binaries is also supported.
The correct packages must be installed according to the host operating system in use. Red Hat Enterprise Linux 6 RPM packages can be used only on supported versions of Red Hat Enterprise Linux 6, and Red Hat Enterprise Linux 7 RPM packages can be used only on supported versions of Red Hat Enterprise Linux 7.
Before installing Red Hat Developer Toolset 4.0, it is recommended to apply all available Red Hat Enterprise Linux errata updates. This will enable all Red Hat Developer Toolset features and apply fixes that can otherwise impact the tools or built code.
Red Hat Developer Toolset 4.0 requires systems to be subscribed to the
Optional
channel in order to access all the necessary dependent packages required by the Red Hat Developer Toolset toolchain.
If you use Red Hat Subscription Manager:
- On Red Hat Enterprise Linux 6, select System → Administration → Add/Remove Software from the panel and navigate to System → Software Sources.
- On Red Hat Enterprise Linux 7, you can add these repositories by navigating to Applications → System Tools → Red Hat Subscription Manager.
Then enable the
Optional
channel for your system. For detailed information, see https://access.redhat.com/solutions/392003.
Users of RHN Classic or Red Hat Satellite can enable the
Optional
channel by following the instructions at https://access.redhat.com/solutions/70019.
1.2. Installation and Upgrading
Use of Red Hat Developer Toolset 4.0 requires the removal of any earlier pre-release versions, including Beta releases. If you have installed any previous version of Red Hat Developer Toolset, uninstall it from your system as described in the Uninstalling Red Hat Developer Toolset section of the Red Hat Developer Toolset User Guide.
Note that installing Red Hat Developer Toolset 4.x in parallel with Red Hat Developer Toolset 3.x, Red Hat Developer Toolset 2.x, or Red Hat Developer Toolset 1.x is supported.
For detailed information on installation of Red Hat Developer Toolset 4.0 see the Installing Red Hat Developer Toolset chapter of the Red Hat Developer Toolset User Guide.
The in-place upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7 is not supported by Red Hat Developer Toolset. As a consequence, the installed components might not work correctly after the upgrade. If you want to upgrade from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, it is strongly recommended to remove all Red Hat Developer Toolset packages, perform the in-place upgrade, update the Red Hat Developer Toolset repository, and install the Red Hat Developer Toolset packages again. It is advisable to back up all data before upgrading.
