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

• Ubuntu 14.04, 16.04, 17.04, 18.04

1. 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 

2. 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 

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

$ cd <workspace> $ mkdir build 

4. Build IGC using commands:

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

5. Install IGC

$ sudo make install
