How can I install glibc version 2.35 on Ubuntu 20.04?

I’ve been diving into some software lately, and I stumbled upon a bit of a predicament. So, here’s the deal: I’m trying to get glibc version 2.35 installed on Ubuntu 20.04, but I feel like I’m hitting a wall. I know 20.04 is a stable LTS release, but I need this specific version of glibc for a project I’m working on, and I’m not entirely sure how to go about it.

Initially, I thought this would be as simple as using the APT package manager, but lo and behold, I quickly discovered that the default repositories for Ubuntu 20.04 only carry older versions of glibc. Of course, I checked online, and it seems like people have various methods, but I don’t know which one is the most reliable. I came across some instructions suggesting that I could manually download and compile it from source, but that sounds a bit risky, considering that I wouldn’t want to mess with system libraries.

I mean, glibc is kind of a big deal, right? It’s part of the core libraries for a Linux system, and I definitely don’t want to break anything that’s working. Then I heard some folks mention using a chroot environment or even Docker to run the newer version without messing up my existing setup. That sounds intriguing, but I’m not sure if I’m overcomplicating things or if that’s the best way forward.

I also read that there could be dependencies that come with this newer version, and I’m just a bit overwhelmed thinking about how to resolve those issues if they arise. So, if anyone here has experience with this or knows of a straightforward way to accomplish it, I would really appreciate your advice! Ideally, I’d like to keep my current system intact, but I also want to get this working, if at all possible. Any tips, tricks, or personal experiences would be super helpful. Thanks a ton in advance!

    1. glibc 2.35 on Ubuntu 20.04


      So, getting glibc 2.35 on Ubuntu 20.04 can be a bit tricky, but it’s totally doable! You’re right that Ubuntu 20.04 sticks to older versions in the repos, so you’ve got a couple of options to consider.

      First off, compiling from source is a path you could take, but I get the hesitation. Messing with system libraries can be risky; breaking your system is a real concern. If you decide to go this route, make sure to follow a good guide. Generally, it involves:

      1. Downloading the glibc source code.
2. Installing build dependencies.
3. Configuring the build.
4. Compiling and installing it.

      Just remember to do it in a separate directory so it doesn’t mess with your system’s version. However, keep in mind that this can lead to potential compatibility issues.

      A safer alternative would definitely be using a chroot environment or Docker. This way, you can create an isolated environment where you can install whatever version you want without affecting the rest of your system. Here’s a quick overview:

      1. For Docker:
   - Install Docker.
   - Create a new Docker container with a newer Ubuntu version.
   - Install glibc 2.35 inside the container.

2. For chroot:
   - Create a chroot environment with a new system (maybe use debootstrap).
   - Enter the chroot and install glibc 2.35.

      Using Docker might be easier since it’s more common and has tons of documentation to help you out. And yeah, managing dependencies is a concern, but often it’s simpler in an isolated environment because each setup can have its own package dependencies without clashing with others.

      Overall, I’d suggest starting with Docker if you can. It’s pretty cool, and once you have it set up, you get to keep your main system safe while still getting that glibc version you need. Good luck with your project!




    2. Installing glibc 2.35 on Ubuntu 20.04

      To install glibc version 2.35 on Ubuntu 20.04 without jeopardizing your system’s stability, you should consider using a containerized environment like Docker. Docker allows you to create isolated environments, enabling you to run applications with specific dependencies without interfering with the host system’s libraries. You can pull a base image of a newer Ubuntu version that includes glibc 2.35, or directly compile glibc 2.35 within Docker. This method minimizes risk since any changes made within the container won’t affect your base OS, and you can test your project within this clean environment. It’s crucial to ensure you have Docker installed; once you do, you can run commands to either pull the appropriate version or build it from source in a Dockerfile.

      If you prefer to compile glibc 2.35 from source manually, be diligent and prepared for potential dependencies and conflicts. First, create a dedicated directory for the build, such as `~/glibc-build`, and clone the glibc repository for the required version. When configuring the build, use options to specify the installation prefix (e.g., `–prefix=/opt/glibc-2.35`) to keep it separate from system libraries. After the compilation, use a tool like `LD_LIBRARY_PATH` to manage the paths during execution in your project, ensuring you don’t accidentally revert to the system’s glibc version. Continuous testing and careful verification will be vital to ensure nothing breaks. Make backups and consider snapshots if you’re running in a virtualized or lxd environment to maintain a stable rollback point.
