Chapter 1. LLVM Toolset
LLVM Toolset is a Red Hat offering for developers on Red Hat Enterprise Linux (RHEL). It provides the LLVM compiler infrastructure framework, the Clang compiler for the C and C++ languages, the LLDB debugger, and related tools for code analysis.
For Red Hat Enterprise Linux 8, LLVM Toolset is available as a module. LLVM Toolset is available as packages for Red Hat Enterprise Linux 9.
1.1. LLVM Toolset components
The following components are available as a part of LLVM Toolset:
| Name | Version | Description |
|---|---|---|
| clang | 16.0.6 | An LLVM compiler front end for C and C++. |
| lldb | 16.0.6 | A C and C++ debugger using portions of LLVM. |
| compiler-rt | 16.0.6 | Runtime libraries for LLVM and Clang. |
| llvm | 16.0.6 | A collection of modular and reusable compiler and toolchain technologies. |
| libomp | 16.0.6 | A library for using Open MP API specification for parallel programming. |
| lld | 16.0.6 | An LLVM linker. |
| python-lit | 16.0.6 | A software testing tool for LLVM- and Clang-based test suites. |
The CMake build manager is not part of LLVM Toolset. On Red Hat Enterprise Linux 8, CMake is available in the system repository. On Red Hat Enterprise Linux 9, CMake is available in the system repository. For more information on how to install CMake, see Installing CMake on Red Hat Enterprise Linux.
1.2. LLVM Toolset compatibility
LLVM Toolset is available for Red Hat Enterprise Linux 8 and Red Hat Enterprise Linux 9 on the following architectures:
- AMD and Intel 64-bit
- 64-bit ARM
- IBM Power Systems, Little Endian
- 64-bit IBM Z
1.3. Installing LLVM Toolset
Complete the following steps to install LLVM Toolset including all development and debugging tools as well as dependent packages.
Prerequisites
- All available Red Hat Enterprise Linux updates are installed.
Procedure
On Red Hat Enterprise Linux 8, install the llvm-toolset module by running:
yum module install llvm-toolset
# yum module install llvm-toolset
This does not install the LLDB debugger or the python3-lit package on Red Hat Enterprise Linux 8. To install the LLDB debugger and the python3-lit package, run:
yum install lldb python3-lit
# yum install lldb python3-lit
On Red Hat Enterprise Linux 9, install the llvm-toolset package by running:
dnf install llvm-toolset
# dnf install llvm-toolset
This does not install the LLDB debugger or the python3-lit package on Red Hat Enterprise Linux 9. To install the LLDB debugger and the python3-lit package, run:
dnf install lldb python3-lit
# dnf install lldb python3-lit1.4. Installing the CMake build manager
The CMake build manager is a tool that manages the build process of your source code independently from your compiler. CMake can generate a native build environment to compile source code, create libraries, generate wrappers, and build executable files.
Complete the following steps to install the CMake build manager.
Prerequisites
-
LLVM Toolset is installed.
For more information, see Installing LLVM Toolset.
Procedure
To install CMake, run the following command:
- On Red Hat Enterprise Linux 8:
yum install cmake
# yum install cmake- On Red Hat Enterprise Linux 9:
dnf install cmake
# dnf install cmakeAdditional resources
- For more information on the CMake build manager, see the official CMake documentation overview About CMake.
For an introduction to using the CMake build manager, see:
- The CMake Reference Documentation Introduction.
- The official CMake documentation CMake Tutorial.
1.5. Installing LLVM Toolset documentation
You can install documentation for LLVM Toolset on your local system.
