| 9 | # - We have to nest our variables dictionaries multiple levels deep, so that |
| 10 | # this and other gyp files can rely on previously-set variable values in |
| 11 | # their 'variables': { 'conditions': [] } clauses. |
| 12 | # |
| 13 | # Example 1: |
| 14 | # Within this file, we use the value of variable 'skia_os' to set the |
| 15 | # value of variable 'os_posix', so 'skia_os' must be defined within a |
| 16 | # "more inner" (enclosed) scope than 'os_posix'. |
| 17 | # |
| 18 | # Example 2: |
| 19 | # http://src.chromium.org/viewvc/chrome/trunk/src/third_party/libjpeg/libjpeg.gyp?revision=102306 , |
| 20 | # which we currently import into our build, uses the value of 'os_posix' |
| 21 | # within the 'conditions' list in its 'variables' dict. |
| 22 | # In order for that to work, it needs the value of 'os_posix' to have been |
| 23 | # set within a "more inner" (enclosed) scope than its own 'variables' dict. |
| 24 | # |
| 25 | # - On the other hand, key/value pairs of a given 'variable' dict are only |
| 26 | # inherited by: |
| 27 | # 1. directly enclosing 'variable' dicts, and |
| 28 | # 2. "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 | |
| 50 | # Re-define all variables defined within the level-3 'variables' dict, |
| 51 | # so that siblings of the level-2 'variables' dict can see them. |
