51 # Managing module exports and imports.
53 # A module can 'import' another module, by calling emugl-import. This will
54 # make the current LOCAL_MODULE inherit various definitions exported from
55 # the imported module.
57 # Module exports are defined by calling emugl-export. Here is an example:
59 # $(call emugl-begin-static-library,foo)
60 # LOCAL_SRC_FILES := foo.c
61 # $(call emugl-export,C_INCLUDES,$(LOCAL_PATH))
62 # $(call emugl-export,SHARED_LIBRARIES,libcutils)
63 # $(call emugl-end-module)
65 # $(call emugl-begin-shared-library,bar)
66 # LOCAL_SRC_FILES := bar.cpp
67 # $(call emugl-import,foo)
68 # $(call emugl-end-module)
70 # Here, we define a static library named 'foo' which exports an include
71 # path and a shared library requirement, and a shared library 'bar' which
74 # What this means is that:
76 # - 'bar' will automatically inherit foo's LOCAL_PATH in its LOCAL_C_INCLUDES
77 # - 'bar' will automatically inherit libcutils in its own LOCAL_SHARED_LIBRARIES
79 # Note that order of declaration matters. If 'foo' is defined after 'bar' in
80 # the example above, nothing will work correctly because dependencies are
81 # computed at import time.
84 # IMPORTANT: Imports are transitive, i.e. when module A imports B,
85 # it automatically imports anything imported by B too.
87 # This is the list of recognized export types we support for now.
