34# This file defines Glslang's build infra dependencies for GN builds.
35# It assumes you have already have the source files for Glslang
36# *and* its dependencies (as downloaded by ./update_glslang_sources.py)
37
38# Usage:
39#   1. Get Chromium depot_tools, and put it in your path.
40#      See https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up
41#
42#   2. From the Glslang source tree:
43#
44#      # Get additional build tooling, using the info in the DEPS file.
45#      gclient sync --gclientfile=standalone.gclient
46#
47#   3. One of the tools downloaded in the previous step is the binary for 'gn'.
48#      Put it on your path.
49#
50#      # This is for Linux amd64 environments:
51#      PATH=$(pwd)/build/linux64:$PATH
52#
53#   3. Create a build tree with Ninja build recipes.
54#
55#      gn gen out/Debug
56#
57#      # Or disable HLSL support:
58#      gn gen out/Debug-no-hlsl --args="glslang_enable_hlsl=false"
59#
60#      # Or make a release build without HLSL support:
61#      gn gen out/Release --args="glslang_enable_hlsl=false is_debug=false"
62#
63#   4. Use ninja to build the project
64#
65#      ninja -C out/Debug
