Chapter 1. System Requirements

This chapter specifies hardware requirements and contains information related to the installation of Red Hat Developer Toolset 8.0.

1.1. Installation Prerequisites

Red Hat Developer Toolset 8.0 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.
Red Hat Developer Toolset 8.0 supports the following architectures on Red Hat Enterprise Linux 7:
  • The 64-bit ARM architecture (AArch64)
  • IBM POWER, big endian
  • IBM POWER, little endian
  • IBM Z
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 8.0, 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 8.0 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. Packages from the Optional channel are listed in the Red Hat Software Collections 3.2 Release Notes.
If you use Red Hat Subscription Manager:
  • On Red Hat Enterprise Linux 6, select SystemAdministrationAdd/Remove Software from the panel and navigate to SystemSoftware Sources.
  • On Red Hat Enterprise Linux 7, you can add these repositories by navigating to ApplicationsSystem ToolsRed Hat Subscription Manager.
Then enable the Optional channel for your system. For detailed information, see https://access.redhat.com/solutions/392003.
Users of Red Hat Satellite can enable the Optional channel by following the instructions at https://access.redhat.com/solutions/70019.
Since Red Hat Developer Toolset 4.1, the content is available also in the ISO format at https://access.redhat.com/downloads, specifically for Server and Workstation.

Note

Packages that require the Optional channel cannot be installed from the ISO image. A list of packages that require enabling of the Optional channel is provided in the Red Hat Software Collections Release Notes.
Beta content is unavailable in the ISO format.

1.2.  Installation and Upgrading

Use of Red Hat Developer Toolset 8.0 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 8.x in parallel with Red Hat Developer Toolset 7.x is supported.
For detailed information on installation of Red Hat Developer Toolset 8.0 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.
