Ethereum: cgminer Installation Issue on Raspberry Pi
As a miner, you rely on software like cgminer to extract cryptocurrency from your mining rig. However, when attempting to install this crucial tool on a raspberry pi running raspbian, you encounter an error message that seems obscure and frustrating. In this article, we’ll delve into the reasons behind this issue and provide step-by-step solutions to resolve it.
The Error:
The Error Message Typically Includes The Following Text:
`
Configure: Error: Can’t Find Cflags or Ldflags
Could not compile cgminer due to a missing linker definition for ‘Scrypt’
Found multiple definitions of __scrypt cryptocurrency
This message suggests that either the compiler is unable to find the necessary flags (cflags and ldflags), or there’s an issue with linking against the Scrypt Library.
Why this Error Occurs:
- MISSING CFLAGS OR LDFLAGS : The
Configure 'Script expects A specific set of competing flags to be installed on your system. These flags are usually provided by the
-C flag when compiling, followed by the desired options. However, some versions of Raspbian might not include these flags in their default installation.
- Missing Scrypt Library : Cgminer Requires the
Scrypt
Library to Function Properly. This library is typically linked against during the compilation process, but it presence or absence can be a problem.
Solutions:
Solution 1: Check and Instal Additional Compiler Flags
On Raspbian, you can add additional compiler flags using the following commands:
`Bash
Sudo Apt Update
Sudo Apt Install -Y Build-Essential Dev-Dev Libz-Dev
`
After running these commands, try re-running the Configure
script:
`
./configure -Cflags = -L/Path/To/Cryptocurrency/LCRYPTOCurrency -lcryptocurrency
`
Replace /path/to/cryptocurrency/libscrypt
with the actual path to your Scrypt Library on your system.
Solution 2: CGMINER UPDATE
The latest version of Cgminer includes updated build instructions and fixes. You Can Update It Using:
`Bash
Sudo Apt Update
Sudo apt install -Y cgminer
`
This should include any necessary compiler flags or dependencies required for the miner to function correctly.
Troubleshooting:
To Further troubleshoot, you can try the following steps:
- Check your Raspbian Installation and verify that the
Scrypt
Library is indeed linked against during during compilation.
- Ensure that your system’s compiler flags are set up correctly.
- If using a different version of CGMINER, ensure it’s compatible with your system’s architecture.
Conclusion:
Installing cgminer on a raspberry pi can be a straightforward process when you address the potential issues outlined in this article. By following these steps and troubleshooting tips, you should be able to resolve the `Configure ‘error and successfully install cgminer for your cryptocurrency mining needs. Happy Mining!
