# Dependencies

To compile **oclHashcat** the following third party libraries are required:

    ADL_SDK v8.0 - http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/
    cuda v7.5 - https://developer.nvidia.com/cuda-downloads
    GDK v352_55 - https://developer.nvidia.com/gpu-deployment-kit
    NVIDIA Driver v352.21 - https://www.nvidia.com/download/driverResults.aspx/86390/en-us
    NVAPI R352 - https://developer.nvidia.com/nvapi
    AMD-APP-SDK v3.0 - http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/
    
To be able to compile the ocl binaries, it is required to have the latest stable driver from AMD installed.
(fglxr must be installed and initialized)

    http://support.amd.com/

The next thing to do is download all the third party libraries listed above and put these files into the *deps/tmp* directory.

The following files are needed inside the *deps/tmp* directory:
    
    ADL_SDK8.zip
    R352-developer.zip
    cuda_7.5.18_linux.run
    NVIDIA-Linux-x86_64-352.21.run
    gdk_linux_amd64_352_55_release.run
    AMD-APP-SDKInstaller-v3.0.130.135-GA-linux64.tar.bz2

Now just execute the following script to complete the installation of dependencies (check for an updated version in **docs/deps.sh**):

# Building oclHashcat
First get a copy of **oclHashcat** repository

```sh
$ git clone https://github.com/hashcat/oclHashcat.git
```

Now simply jump in and type "make all"

```sh
$ cd oclHashcat
$ make all
```

Useful tricks:
- build only *Linux* binaries
```sh
$ make linux
```
- build only *Windows* binaries
```sh
$ make windows
```
- build only *AMD kernel* binaries
```sh
$ make amd_all
```
- build only *NVIDIA kernel* binaries
```sh
$ make nv_all
```

Enjoy your fresh **oclHashcat** binaries ;)
