GLIBCXX_3.4.15 Not Found: Resolving the Error in Ubuntu

When attempting to run compiled programs, an error message indicating that "GLIBCXX_3.4.15 not found" can arise. This error is encountered due to the absence of the necessary version of the GLIBCXX library.

Issue Resolution

To resolve this issue, one can install the GLIBCXX_3.4.15 package, which is a dependency for running specific programs. As described in the given solution, the user encountered a separate problem while compiling gcc. In their case, the installation via "sudo make install" did not resolve the issue.

Alternative Solution

Implementation

To implement this solution, follow these steps:

1. Copy the file "libstdc .so.6.0.15" from the gcc source code directory to "/usr/lib."
2. Create a symbolic link from "libstdc .so.6" to "libstdc .so.6.0.15." This redirects the operating system to the newly copied library file.
