Dependencies

• Common Clang - https://github.com/intel/opencl-clang
• Clang Source - https://github.com/llvm-mirror/clang
• Khronos OpenCL Headers - https://github.com/KhronosGroup/OpenCL-Headers
• LLVM Source - https://github.com/llvm-mirror/llvm

Supported Linux versions

IGC is supported on the following 32/64 bits Linux operating systems:

• Ubuntu 14.04, 16.04, 17.04

Building

1. Install prerequisites

Building IGC need flxe, bision, clang 4.0, cmake version later than 3.4.3 and libz. You can install required packages on ubuntu 16.04 like below:

$ sudo apt-get install flex bison clang-4.0 libz-dev cmake

2. Download all dependencies and create workspace folder as below:

workspace
      |- clang_source           https://github.com/llvm-mirror/clang
      |- common_clang           https://github.com/intel/opencl-clang
      |- llvm_patches           https://github.com/intel/llvm-patches
      |- llvm_source            https://github.com/llvm-mirror/llvm
      |- igc                    https://github.com/intel/intel-graphics-compiler
      |- opencl_headers         https://github.com/KhronosGroup/OpenCL-Headers

Example command:
$ git clone -b release_40 https://github.com/llvm-mirror/clang clang_source
$ git clone https://github.com/intel/opencl-clang common_clang
$ git clone https://github.com/intel/llvm-patches llvm_patches
$ git clone -b release_40 https://github.com/llvm-mirror/llvm llvm_source
$ git clone https://github.com/intel/intel-graphics-compiler igc
$ git clone https://github.com/KhronosGroup/OpenCL-Headers
$ cp -a OpenCL-Headers/opencl22 opencl_headers

3. Under workspace create a build folder. For example:

$ mkdir build

4. Build IGC using commands:

$ cd build
$ cmake -DIGC_OPTION__OUTPUT_DIR=../igc-install/Release \
    -DCMAKE_BUILD_TYPE=Release -DIGC_OPTION__ARCHITECTURE_TARGET=Linux64 \
    ../igc/IGC
$ make -j`nproc`

Supported Platforms

• Intel Core Processors supporting Gen8 graphics devices
• Intel Core Processors supporting Gen9 graphics devices
• Intel Core Processors supporting Gen10 graphics devices
• Intel Atom Processors supporting Gen9 graphics devices
