"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 # We use 'skia_os' instead of 'OS' throughout our gyp files, to allow 44 # for cross-compilation (e.g. building for either MacOS or iOS on Mac). 45 # We set it automatically based on 'OS' (the host OS), but allow the 46 # user to override it via GYP_DEFINES if they like. 47 'skia_os%': '<(OS)', 48 49 'skia_android_framework%': 0, 50 'skia_arch_type%': 'x86', 51 'arm_version%': 0, 52 'arm_neon%': 0, 53 }, 54 55 # Re-define all variables defined within the level-3 'variables' dict, 56 # so that siblings of the level-2 'variables' dict can see them. 57 # (skia_os will depend on skia_android_framework.) 58 'skia_android_framework%': '<(skia_android_framework)', 59 'skia_arch_type%': '<(skia_arch_type)', 60 'arm_version%': '<(arm_version)', 61 'arm_neon%': '<(arm_neon)', 62 63 'conditions': [ 64 [ 'skia_android_framework == 1', { 65 'skia_os%': 'android', 66 'skia_chrome_utils%': 0, 67 'skia_use_system_json%': 1, 68 }, { 69 'skia_os%': '<(skia_os)', 70 'skia_chrome_utils%': 1, 71 'skia_use_system_json%': 0, 72 }], 73 [ 'skia_os == "win"', { 74 'os_posix%': 0, 75 }, { 76 'os_posix%': 1, 77 }], 78 [ 'skia_os in ["linux"]', { 79 'skia_poppler_enabled%': 1, 80 }, { 81 'skia_poppler_enabled%': 0, 82 }], 83 [ 'skia_os in ["linux", "freebsd", "openbsd", "solaris", "mac"] or skia_arch_type == "arm64"', { 84 'skia_arch_width%': 64, 85 }, { 86 'skia_arch_width%': 32, 87 }], 88 [ 'skia_os == "android"', { 89 'skia_static_initializers%': 0, 90 }, { 91 'skia_static_initializers%': 1, 92 }], 93 [ 'skia_os == "ios"', { 94 'skia_arch_type%': 'arm', 95 'arm_version%': 7, 96 'arm_neon%': 0, # neon asm files known not to work with the ios build 97 }], 98 [ 'skia_os in ["android", "nacl"] and not skia_android_framework', 99 # skia_freetype_static - on OS variants that normally would 100 # dynamically link the system FreeType library, don't do 101 # that; instead statically link to the version in 102 # third_party/freetype and third_party/externals/freetype. 103 { 104 'skia_freetype_static%': '1', 105 }, { 106 'skia_freetype_static%': '0', 107 } 108 ], 109 ], 110 111 # skia_giflib_static - on OS variants that normally would link giflib 112 # with '-lgif' and include the headers from '/usr/include/gif_lib.h', 113 # don't do that; instead compile and staticlly link the version of 114 # giflib in third_party/externals/giflib. 115 'skia_giflib_static%': '0', 116 117 # skia_libpng_static - on OS variants that normally would link libpng 118 # with '-lpng' and include the headers from '/usr/include/png.h', 119 # don't do that; instead compile and staticlly link the version of 120 # libpng in third_party/externals/libpng. 121 'skia_libpng_static%': '0', 122 123 # skia_zlib_static - on OS variants that normally would link zlib with 124 # '-lz' or libz.dylib and include the headers from '<zlib.h>', 125 # don't do that; instead compile and staticlly link the version of 126 # zlib in third_party/externals/zlib. 127 'skia_zlib_static%': '0', 128 129 # skia_no_fontconfig - On POSIX systems that would normally use the 130 # SkFontHost_fontconfig interface; use the SkFontHost_linux 131 # version instead. 132 'skia_no_fontconfig%': '0', 133 134 'skia_sanitizer%': '', 135 'skia_scalar%': 'float', 136 'skia_mesa%': 0, 137 'skia_stroke_path_rendering%': 0, 138 'skia_android_path_rendering%': 0, 139 'skia_resource_cache_mb_limit%': 0, 140 'skia_resource_cache_count_limit%': 0, 141 'skia_angle%': 0, 142 'skia_directwrite%': 0, 143 'skia_gpu%': 1, 144 'skia_osx_deployment_target%': '', 145 'skia_profile_enabled%': 0, 146 'skia_win_debuggers_path%': '', 147 'skia_shared_lib%': 0, 148 'skia_opencl%': 0, 149 'skia_force_distancefield_fonts%': 0, 150 151 # These variables determine the default optimization level for different 152 # compilers. 153 'skia_default_vs_optimization_level': 3, # full (/Ox) 154 'skia_default_gcc_optimization_level': 3, # -O3 155 }, 156 157 'conditions': [ 158 [ 'skia_os == "win" and skia_arch_width == 32 or ' 159 'skia_os in ["linux", "freebsd", "openbsd", "solaris", "android"] ' 160 'and skia_android_framework == 0 or ' 161 'skia_os == "mac" and skia_arch_width == 32', { 162 'skia_warnings_as_errors%': 1, 163 }, { 164 'skia_warnings_as_errors%': 0, 165 }], 166 167 # This variable allows the user to customize the optimization level used 168 # by the compiler.
