"sibling" 'variable' dicts (which, I guess, are combined into a single 29 # 'variable' dict during gyp processing) 30 # and NOT inherited by "uncles" (siblings of directly enclosing 'variable' 31 # dicts), so we have to re-define every variable at every enclosure level 32 # within our ridiculous matryoshka doll of 'variable' dicts. That's why 33 # we have variable definitions like this: 'skia_os%': '<(skia_os)', 34 # 35 # See http://src.chromium.org/viewvc/chrome/trunk/src/build/common.gypi?revision=127004 , 36 # which deals with these same constraints in a similar manner. 37 # 38 'variables': { # level 1 39 'angle_path%': '../', 40 41 'skia_mojo%': '0', 42 43 'variables': { # level 2 44 # Variables needed by conditions list within the level-2 variables dict. 45 'variables': { # level 3 46 'variables': { # level 4 47 # We use 'skia_os' instead of 'OS' throughout our gyp files, to allow 48 # for cross-compilation (e.g. building for either MacOS or iOS on Mac). 49 # We set it automatically based on 'OS' (the host OS), but allow the 50 # user to override it via GYP_DEFINES if they like. 51 'skia_os%': '<(OS)', 52 }, 53 'skia_os%': '<(skia_os)', 54 'vulkan_merged_into_skia': '1', 55 'skia_android_framework%': 0, 56 'conditions' : [ 57 [ 'skia_os in ["linux", "freebsd", "openbsd", "solaris", "mac"]', { 58 'skia_arch_type%': 'x86_64', 59 }, { 60 'skia_arch_type%': 'x86', 61 }], 62 # RAW codec needs exceptions.
