23 |

24 |
+# The multibuild eclass aims to provide a generic framework for building |
25 |
+# multiple 'variants' of a package (e.g. multilib, Python |
26 |
+# implementations). |

+# @ECLASS-VARIABLE: MULTIBUILD_VARIANTS |
44 |
+# @DESCRIPTION: |
45 |
+# An array specifying all enabled variants which multilib_foreach* will |
46 |
+# execute the process for. |
47 |
+# |
48 |
+# In ebuild, it can be set in global scope. Eclasses should set it |
49 |
+# locally in function scope to support nesting properly. |
50 |
+# |
51 |
+# Example: |
52 |
+# @CODE |
53 |
+# python_foreach_impl() { |
54 |
+# local MULTIBUILD_VARIANTS=( python{2_5,2_6,2_7} ... ) |
55 |
+# multibuild_foreach_impl python_compile |
56 |
+# } |
57 |
+# @CODE |
58 |
+ |
59 |
+# @ECLASS-VARIABLE: MULTIBUILD_VARIANT |
60 |
+# @DESCRIPTION: |
61 |
+# The current variant which the function was executed for. |
62 |
+# |
63 |
+# Example value: |
64 |
+# @CODE |
65 |
+# python2_6 |
66 |
+# @CODE |
67 |
+ |
68 |
+# @ECLASS-VARIABLE: MULTIBUILD_ID |
69 |
+# @DESCRIPTION: |
70 |
+# The unique identifier for a multibuild run. In a simple run, it is |
71 |
+# equal to MULTIBUILD_VARIANT. In a nested multibuild environment, it |
72 |
+# contains the complete selection tree. |
73 |
+# |
74 |
+# It can be used to create variant-unique directories and files. |
75 |
+# |
76 |
+# Example value: |
77 |
+# @CODE |
78 |
+# amd64-double |
79 |
+# @CODE |
80 |

81 |
+# @ECLASS-VARIABLE: BUILD_DIR |
82 |
+# @DESCRIPTION: |
83 |
+# The current build directory. In global scope, it is supposed to |
84 |
+# contain an 'initial' build directory; if unset, it defaults to ${S}. |
85 |
+# |
86 |
+# multibuild_foreach() sets BUILD_DIR locally to variant-specific build |
87 |
+# directories based on the initial value of BUILD_DIR. |
88 |
+# |
89 |
+# Example value: |
90 |
+# @CODE |
91 |
+# ${WORKDIR}/foo-1.3-python2_6 |
92 |
+# @CODE |

98 |
+# variants. |
99 |
+# |
100 |
