"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 'variables': { # level 2 40 41 # Variables needed by conditions list within the level-2 variables dict. 42 'variables': { # level 3 43 'variables': { # level 4 44 # We use 'skia_os' instead of 'OS' throughout our gyp files, to allow 45 # for cross-compilation (e.g. building for either MacOS or iOS on Mac). 46 # We set it automatically based on 'OS' (the host OS), but allow the 47 # user to override it via GYP_DEFINES if they like. 48 'skia_os%': '<(OS)', 49 }, 50 'skia_os%': '<(skia_os)', 51 52 'skia_android_framework%': 0, 53 'conditions' : [ 54 [ 'skia_os in ["linux", "freebsd", "openbsd", "solaris", "mac"]', { 55 'skia_arch_type%': 'x86_64', 56 }, { 57 'skia_arch_type%': 'x86', 58 }], 59 ], 60 'arm_version%': 0, 61 'arm_neon%': 0, 62 'skia_egl%': 0, 63 }, 64 65 # Re-define all variables defined within the level-3 'variables' dict, 66 # so that siblings of the level-2 'variables' dict can see them. 67 # (skia_os will depend on skia_android_framework.) 68 'skia_android_framework%': '<(skia_android_framework)', 69 'skia_arch_type%': '<(skia_arch_type)', 70 'arm_version%': '<(arm_version)', 71 'arm_neon%': '<(arm_neon)', 72 'skia_egl%': '<(skia_egl)', 73 74 'conditions': [ 75 [ 'skia_android_framework == 1', { 76 'skia_os%': 'android', 77 'skia_chrome_utils%': 0, 78 'skia_use_system_json%': 1, 79 }, { 80 'skia_os%': '<(skia_os)', 81 'skia_chrome_utils%': 1, 82 'skia_use_system_json%': 0, 83 }], 84 [ 'skia_os == "win"', { 85 'os_posix%': 0, 86 }, { 87 'os_posix%': 1, 88 }], 89 ['"64" in skia_arch_type', { 90 'skia_arch_width%': 64, 91 }, { 92 'skia_arch_width%': 32, 93 }], 94 [ 'skia_os == "android"', { 95 'skia_static_initializers%': 0, 96 'skia_egl%': 1, 97 }, { 98 'skia_static_initializers%': 1, 99 }], 100 [ 'skia_os == "ios"', { 101 'skia_arch_type%': 'arm', 102 'arm_version%': 7, 103 'arm_neon%': 0, # neon asm files known not to work with the ios build 104 }], 105 [ 'skia_os == "android" and not skia_android_framework', 106 # skia_freetype_static - on OS variants that normally would 107 # dynamically link the system FreeType library, don't do 108 # that; instead statically link to the version in 109 # third_party/freetype and third_party/externals/freetype. 110 { 111 'skia_freetype_static%': '1', 112 }, { 113 'skia_freetype_static%': '0', 114 } 115 ], 116 ], 117 118 # skia_no_fontconfig - On POSIX systems that would normally use the 119 # SkFontHost_fontconfig interface; use the SkFontHost_linux 120 # version instead. 121 'skia_no_fontconfig%': '0', 122 'skia_embedded_fonts%': '0', 123 124 'skia_sanitizer%': '', 125 'skia_scalar%': 'float', 126 'skia_mesa%': 0, 127 'skia_gpu_extra_dependency_path%': '', 128 'skia_stroke_path_rendering%': 0, 129 'skia_android_path_rendering%': 0, 130 'skia_resource_cache_mb_limit%': 0, 131 'skia_resource_cache_count_limit%': 0, 132 'skia_angle%': 0, 133 'skia_gdi%': 0, 134 'skia_gpu%': 1, 135 'skia_osx_deployment_target%': '', 136 'skia_profile_enabled%': 0, 137 'skia_win_debuggers_path%': '', 138 'skia_shared_lib%': 0, 139 'skia_opencl%': 0, 140 'skia_force_distance_field_text%': 0, 141 142 # These variables determine the default optimization level for different 143 # compilers. 144 'skia_default_vs_optimization_level': 3, # full (/Ox) 145 'skia_default_gcc_optimization_level': 3, # -O3 146 }, 147 148 'conditions': [ 149 [ 'skia_os in ["mac", "linux", "freebsd", "openbsd", "solaris", "android", "win"] ' 150 'and skia_android_framework == 0', { 151 'skia_warnings_as_errors%': 1, 152 }, { 153 'skia_warnings_as_errors%': 0, 154 }], 155 156 # This variable allows the user to customize the optimization level used 157 # by the compiler.
