run linux program made for lower GLIBC than mine

==========================
linux how can I have multiple versions of GLIBC in my system? Without docker and without compiling . So I can use them with patchelf interpreter parameter?

One way to have multiple versions of GLIBC on your system without using Docker or compiling is to use a chroot environment. A chroot environment allows you to run a separate instance of the Linux operating system within your existing system.

Here's a general outline of how you can set up a chroot environment with multiple versions of GLIBC:

1. Download and install the necessary version of GLIBC in a separate directory within your system (e.g. /opt/glibc-2.x).
2. Create a chroot environment using the chroot command, specifying the directory where you installed GLIBC as the root directory.
3. Within the chroot environment, you can use the patchelf command with the interpreter parameter to execute programs compiled against the specific version of GLIBC that you installed.

Keep in mind that setting up and maintaining a chroot environment can be complex and may require some trial and error. Additionally, using a chroot environment may not be suitable for all use cases, so make sure to carefully consider whether this approach is appropriate for your specific needs.

One way to run a program that requires a higher version of GLIBC than the one installed on your system is by using a tool called "patchelf." Patchelf is a small utility that can modify the dynamic linker and RPATH of an executable, allowing it to use a different version of the GLIBC library.

Here's how you can use patchelf to run a program with a higher version of GLIBC:

Download and install patchelf on your system. You can usually find it in your distribution's package repository or download it from the official website.

Find the executable file of the program that requires a higher version of GLIBC.

Use the following command to modify the RPATH of the executable to point to a directory where the higher version of GLIBC is installed:


patchelf --set-interpreter /path/to/higher_version_glibc/ld-linux-x86-64.so.2 --set-rpath /path/to/higher_version_glibc/lib:/path/to/higher_version_glibc/lib64 your_program_executable
Replace "/path/to/higher_version_glibc" with the actual path to the directory where the higher version of GLIBC is installed, and "your_program_executable" with the name of the program executable file.

Now run the modified program using the following command:

./your_program_executable
This should allow the program to run using the higher version of GLIBC without making changes to your system or using Docker. Keep in mind that this method may not work for all programs, as some may have additional dependencies that need to be resolved.

One way to run a program written for a lower GLIBC version than the one on your system is to use a tool called patchelf. This tool allows you to modify the dynamic linker and interpreter path in the ELF binary, allowing it to run on a system with a different GLIBC version.

Here's how you can use patchelf to run a program with a lower GLIBC version:

First, install patchelf if you don't already have it on your system. You can install it using your package manager (e.g., sudo apt-get install patchelf on Debian-based systems).
Use the following command to change the interpreter path in the ELF binary:

patchelf --set-interpreter /path/to/older/glibc/ld-linux.so.2 /path/to/your/program
Replace /path/to/older/glibc/ld-linux.so.2 with the path to the older version of the ld-linux.so.2 file on your system, and replace /path/to/your/program with the path to the program you want to run.

Run the program using the modified ELF binary:

./path/to/your/program
This method will allow you to run a program with a lower GLIBC version on your system without making any changes to your system-wide libraries.
