| 3 =============== | |
| 4 mozconfig Files | |
| 5 =============== | |
| 6 | |
| 7 mozconfig files are used to configure how a build works. | |
| 8 | |
| 9 mozconfig files are actually shell scripts. They are executed in a | |
| 10 special context with specific variables and functions exposed to them. | |
| 11 | |
| 12 API | |
| 13 === | |
| 14 | |
| 15 Functions | |
| 16 --------- | |
| 17 | |
| 18 The following special functions are available to a mozconfig script. | |
| 19 | |
| 20 ac_add_options | |
| 21 ^^^^^^^^^^^^^^ | |
| 22 | |
| 23 This function is used to declare extra options/arguments to pass into | |
| 24 configure. | |
| 25 | |
| 26 e.g.:: | |
| 27 | |
| 28 ac_add_options --disable-tests | |
| 29 ac_add_options --enable-optimize | |
| 30 | |
| 31 mk_add_options | |
| 32 ^^^^^^^^^^^^^^ | |
| 33 | |
| 34 This function is used to inject statements into client.mk for execution. | |
| 35 It is typically used to define variables, notably the object directory. | |
| 36 | |
| 37 e.g.:: | |
| 38 | |
| 39 mk_add_options AUTOCLOBBER=1 | |
| 40 | |
| 41 ac_add_options | |
| 42 ^^^^^^^^^^^^^^ | |
| 43 | |
| 44 This is a variant of ac_add_options() which only adds configure options | |
| 45 for a specified application. This is only used when building multiple | |
| 46 applications through client.mk. This function is typically not needed. | |
| 47 | |
| 48 Special mk_add_options Variables | |
| 49 -------------------------------- | |
| 50 | |
| 51 For historical reasons, the method for communicating certain | |
| 52 well-defined variables is via mk_add_options(). In this section, we | |
| 53 document what those special variables are. | |
| 54 | |
| 55 MOZ_OBJDIR | |
| 56 ^^^^^^^^^^ | |
| 57 | |
| 58 This variable is used to define the :term:`object directory` for the current | |
| 59 build. | |
| 60 | |
| 61 Finding the active mozconfig | |
| 62 ============================ | |
| 63 | |
| 64 Multiple mozconfig files can exist to provide different configuration | |
| 65 options for different tasks. The rules for finding the active mozconfig | |
| 66 are defined in the | |
| 67 :py:func:`mozbuild.mozconfig.MozconfigLoader.find_mozconfig` method: | |
| 68 | |
| 69 .. autoclass:: mozbuild.mozconfig.MozconfigLoader | |
| 70 :members: find_mozconfig |
