The error message “libdevice not found at ./libdevice.10.bc” usually occurs when the compiler is unable to locate the libdevice library file in the specified location. The libdevice library contains essential device functions that are used during device code compilation and execution.
To fix this error, you need to ensure that the libdevice library file is available and properly configured. Here are a few possible solutions:
- Upgrade the CUDA toolkit: Make sure you have the latest version of the CUDA toolkit installed. Sometimes, older versions of the CUDA toolkit may not include the libdevice library file required for your specific use case.
- Check the location of your libdevice file: Verify the location of the libdevice library file in your development environment. The default location is usually in the “libdevice” folder within the CUDA installation directory. If the file is not present or located in a different directory, you may need to update the compiler settings to point to the correct path.
- Reinstall CUDA toolkit: If the libdevice library file is missing or misplaced, you can try reinstalling the CUDA toolkit to ensure all necessary files are properly installed.
- Compiler flags and options: If you are manually specifying compiler flags and options, double-check that you are including the necessary flags to link against the libdevice library. For example, you might need to add “-lcudadevrt” or “-ldevice” to your compilation command.
Here is an example of how you can include the necessary compiler flags for linking against the libdevice library:
nvcc -o my_program my_program.cu -lcudadevrt
In this example, “my_program.cu” is the name of your CUDA source file, and the “-lcudadevrt” flag tells the compiler to link against the libdevice library.
