Devtoolset-7-gcc-c and devtoolset-7-gcc Download
This article explores the devtoolset-7-gcc-c and devtoolset-7-gcc components, crucial for developers working with the GCC compiler on Red Hat Enterprise Linux (RHEL) 7. It aims to provide a clear understanding of these tools, their functionalities, and how to effectively download and install them.
Understanding Devtoolset-7-gcc-c and Devtoolset-7-gcc
Devtoolset-7-gcc refers to a collection of development tools, primarily focusing on the GCC compiler. It's a critical package for developers building and compiling applications on RHEL 7 systems. Devtoolset-7-gcc-c is a specific component of this collection, directly related to the C compiler.
Why Use Devtoolset-7-gcc?
Devtoolset-7-gcc offers several advantages:
- Newer Compiler Versions: It provides access to the latest GCC versions, enabling developers to utilize new features and optimize code for better performance.
- Compatibility: It ensures compatibility with newer C++ standards and other language features.
- Bug Fixes: The package includes critical bug fixes and improvements from the GCC development team.
- Parallel Development: Developers can work with the latest tools without affecting existing applications that rely on older compiler versions.
Downloading Devtoolset-7-gcc
Downloading the devtoolset-7-gcc package on RHEL 7 is a straightforward process. Here's how:
- Enable the EPEL Repository: The devtoolset-7-gcc package is available through the EPEL repository. Ensure you've enabled it on your system.
- Install the Package: Once the EPEL repository is enabled, use the following command to install the package:
sudo yum install devtoolset-7
This command will install devtoolset-7-gcc along with other associated tools.
Using Devtoolset-7-gcc
After successful installation, you need to activate the devtoolset-7-gcc environment before compiling code:
scl enable devtoolset-7 bash

Example: Compiling C Code with Devtoolset-7-gcc
scl enable devtoolset-7 bash
gcc -o myprogram myprogram.c
This command will compile the C file myprogram.c using the devtoolset-7-gcc compiler and produce an executable file named myprogram.
Switching Between Devtoolset Versions
You can switch between different devtoolset versions using the scl command. For instance, to switch back to the default compiler version:
scl disable devtoolset-7
Important Considerations
- Dependencies: Ensure your system has the required dependencies for the devtoolset-7-gcc package.
- System Impact: Installing devtoolset-7-gcc might consume additional disk space.
- Environment Variables: Be mindful of environment variables that might affect the compiler selection.
Conclusion
Devtoolset-7-gcc offers a valuable solution for developers on RHEL 7 systems, providing access to newer GCC versions and features. By following the download and installation instructions, you can easily utilize this toolset to enhance your development workflow and build applications with the latest compiler technology.
