Supported Linux versions

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

Ubuntu 14.04, 16.04, 17.04, 18.04

Building

Install prerequisites

Building IGC needs flex, bison, cmake version later than 3.4.3 and libz. You can install required packages on ubuntu 18.04 like below:

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

Download all dependencies and create workspace folder as below:

<workspace>
      |- igc                          https://github.com/intel/intel-graphics-compiler
      |- llvm_patches                 https://github.com/intel/llvm-patches
      |- llvm_source                  https://github.com/llvm-mirror/llvm
            |- projects/opencl-clang  https://github.com/intel/opencl-clang
            |- projects/llvm-spirv    https://github.com/KhronosGroup/SPIRV-LLVM-Translator
            |- tools/clang            https://github.com/llvm-mirror/clang

This can be done using the following commands:

$ cd <workspace>
$ git clone -b release_70 https://github.com/llvm-mirror/llvm llvm_source
$ git clone -b release_70 https://github.com/llvm-mirror/clang llvm_source/tools/clang
$ git clone -b ocl-open-70 https://github.com/intel/opencl-clang llvm_source/projects/opencl-clang
$ git clone -b llvm_release_70 https://github.com/KhronosGroup/SPIRV-LLVM-Translator llvm_source/projects/llvm-spirv
$ git clone https://github.com/intel/llvm-patches llvm_patches
$ git clone https://github.com/intel/intel-graphics-compiler igc
  [If using specific release]
$ cd igc && git checkout -b tag igc_release_2019-01-15

Under workspace create a build folder. For example:

$ cd <workspace>
$ mkdir build

Build IGC using commands:

$ cd build
$ cmake ../igc/IGC
$ make -j`nproc`

Install IGC

$ sudo make install

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
