Ethereum BFGMINER Error: Unable to Load Shared Libraries
The error message BFGMINER error while loading shared libraries' indicates that the Bitcoin GPU mining software, BFGMINER, is encountering issues with loading its shared library files. This can occur due to various reasons, including outdated or corrupted system libraries, inadequate system configuration, or conflicts between different library versions.
Causes of the Error
Some common causes of theBFGMINER error while loading shared libraries’ error include:
- Outdated Linux Distribution: Bitcoin and BFGMINER are designed for specific Ubuntu distributions. If you’re using an older distribution like 12.04LTS, it might be difficult to troubleshoot or update your system.
- Corrupted System Libraries: The
lib mining.solibrary file is necessary for BFGMINER to load the Bitcoin kernel modules. Corrupt system libraries can cause this error.
- Incompatible Library Versions: Different versions of the Bitcoin kernel and BFGMINER libraries may not be compatible, leading to an error when trying to load shared libraries.
Troubleshooting Steps
To resolve the issue, follow these steps:
- Update Linux Distribution and System Libraries:
* Update your Ubuntu distribution using sudo apt update and then sudo apt full-upgrade -y.
* Ensure that all system libraries are up-to-date.
- Check for Corrupted System Libraries
:
* Run the command sudo ldconfig to check if any system libraries have been corrupted.
- Update 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 necessary):
* If you’re using an older Bitcoin kernel version, consider rebuilding it using sudo apt install bitcoin-core=1:0.15.6-2ubuntu3.
Additional Tips
To further troubleshoot the issue, ensure that your system has:
- A compatible graphics driver for your laptop’s GPU (e.g., NVIDIA or AMD).
- The latest BFGMINER version.
- An up-to-date Bitcoin mining pool configuration.
If none of these steps resolve the error, you may want to consider seeking assistance from a qualified Linux administrator or a Bitcoin mining community forum for more detailed guidance.
