When encountering the error message “library not loaded: /usr/local/opt/gmp/lib/libgmp.10.dylib,” it indicates that a library called “libgmp.10.dylib” is not being loaded properly in the specified directory path. This error commonly occurs in macOS systems.
To resolve this issue, you can try the following steps:
- Check if the library file exists in the specified directory. You can navigate to the directory ‘/usr/local/opt/gmp/lib/’ and verify if the ‘libgmp.10.dylib’ library file is present.
- Ensure that the library file has the necessary read and execute permissions. You can use the ‘ls -l’ command to view the file’s permissions. If the permissions appear to be incorrect, you can modify them with the ‘chmod’ command.
- If the library file is missing or damaged, you can try reinstalling the library. This can be done using package managers like Homebrew. Open the Terminal and run the following command:
brew reinstall gmp. This will reinstall the “GNU Multiple Precision Arithmetic Library” (GMP) which includes the required library file. - If the library file is present but still not being loaded, it might be due to a problem with the library search path. You can try updating the library search path by modifying the DYLD_LIBRARY_PATH environment variable. Open the Terminal and execute the command:
export DYLD_LIBRARY_PATH=/usr/local/opt/gmp/lib:$DYLD_LIBRARY_PATH
After setting the environment variable, try running your program again.
By following these steps, you should be able to resolve the “library not loaded” error. If the issue persists, it is recommended to seek further assistance from the relevant developer community or support forums.
Example:
$ ls -l /usr/local/opt/gmp/lib/libgmp.10.dylib
