Ethereum BFGMINER Error: Unable to Load Shared Libraries

The error message BFGMINER error loading shared libraries indicates that the Bitcoin GPU mining software, BFGMINER, is having trouble loading its shared library files. This can happen for a variety of reasons, including outdated or corrupted system libraries, improper system configuration, or conflicts between different library versions.

Causes of the Error

Some common causes of the BFGMINER error loading shared libraries error include:

• Outdated Linux distribution: Bitcoin and BFGMINER are designed for specific Ubuntu distributions. If you are using an older distribution such as 12.04LTS, it may be difficult to resolve the issue or update your system.

• Corrupted system libraries: The lib mining.so library file is required by BFGMINER to load Bitcoin kernel modules. Corrupted system libraries can cause this error.

• Incompatible library versions: Different versions of the Bitcoin kernel and BFGMINER libraries may be incompatible, leading to an error when trying to load shared libraries.

Troubleshooting steps

To resolve the issue, follow these steps:

• Update your Linux distribution and system libraries:

• Update your Ubuntu distribution using sudo apt update, then sudo apt full-upgrade -y.

• Make sure all system libraries are up to date.

• Check for corrupted system libraries:

• Run the sudo ldconfig command to check if any system libraries are corrupted.

• Update the Bitcoin Kernel and BFGMINER libraries:

• Update the Bitcoin kernel version using sudo apt install bitcoin-core=1:0.15.5-6ubuntu2.

• Update the BFGMINER library version using sudo apt install lib mining.so.1 = 4.24.1-1~12.04LTS.

• Disable and re-enable BFGMINER

  :

* Disable BFGMINER by running sudo systemctl disable bfgminer and then re-enable it with sudo systemctl enable bfgminer.

• Rebuild Bitcoin Kernel (if needed):

* If you are using an older version of the Bitcoin kernel, consider rebuilding with sudo apt install bitcoin-core=1:0.15.6-2ubuntu3.

Additional Tips

To further troubleshoot the problem, check if your system has:

• Compatible graphics driver for your laptop’s GPU (eg NVIDIA or AMD).

• Latest version of BFGMINER.

• Updated Bitcoin mining pool configuration.

If none of these steps resolve the error, consider seeking help from a qualified Linux administrator or a Bitcoin mining community forum for more detailed instructions.
