# VanitySearch
A version support custom range scanning and multi address scanning.

This is a modified version of VanitySearch by [JeanLucPons](https://github.com/JeanLucPons/VanitySearch/).

Performance optimization completed by [aaelick](https://github.com/aaelick). **Only one GPU per instance.**

# Build
## Windows

- Intall CUDA SDK and open VanitySearch.sln in Visual C++ 2017.
- You may need to reset your *Windows SDK version* in project properties.
- In Build->Configuration Manager, select the *Release* configuration.

- Note: The current relase has been compiled with CUDA SDK 10.0, if you have a different release of the CUDA SDK, you may need to update CUDA SDK paths in VanitySearch.vcxproj using a text editor. The current nvcc option are set up to architecture starting at 3.0 capability, for older hardware, add the desired compute capabilities to the list in GPUEngine.cu properties, CUDA C/C++, Device, Code Generation.

## Linux
- Edit the makefile and set up the appropriate CUDA SDK and compiler paths for nvcc.
    ```
    ccap=86
    
    ...
    
    CXX        = g++-9
    CUDA       = /usr/local/cuda-11.8
    CXXCUDA    = /usr/bin/g++-9
    ```

- Build:
    ```
    $ make all
    ```
- **Attention!!! You need to use g++-9 or a lower version to compile, otherwise the program will not run properly.**
