Android 編譯時遇到 LOCAL_MODULE_TAGS 的錯誤

編譯時載入模組有時會出現錯誤.....

如果在編譯時出現下列訊息：

build/core/base_rules.mk:74: *** Module name: 01-test

build/core/base_rules.mk:75: *** Makefile location: external/dhcpcd

build/core/base_rules.mk:76: *

build/core/base_rules.mk:77: * Each module must use a LOCAL_MODULE_TAGS in its

build/core/base_rules.mk:78: * Android.mk. Possible tags declared by a module:

build/core/base_rules.mk:79: *

build/core/base_rules.mk:80: * optional, debug, eng, tests, samples

build/core/base_rules.mk:81: *

build/core/base_rules.mk:82: * If the module is expected to be in all builds

build/core/base_rules.mk:83: * of a product, then it should use the

build/core/base_rules.mk:84: * "optional" tag:

build/core/base_rules.mk:85: *

build/core/base_rules.mk:86: * Add "LOCAL_MODULE_TAGS := optional" in the

build/core/base_rules.mk:87: * Android.mk for the affected module, and add

build/core/base_rules.mk:88: * the LOCAL_MODULE value for that component

build/core/base_rules.mk:89: * into the PRODUCT_PACKAGES section of product

build/core/base_rules.mk:90: * makefile(s) where it's necessary, if

build/core/base_rules.mk:91: * appropriate.

build/core/base_rules.mk:92: *

build/core/base_rules.mk:93: * If the component should be in EVERY build of ALL

build/core/base_rules.mk:97: *

build/core/base_rules.mk:98: *** user tag detected on new module - user tags are only supported on legacy modules. Stop.

只需要看第二行 『Makefile location: external/dhcpcd』 的 external/dhcpcd 路徑下，

修改 Android.mk ，

找到第一行的 『Module name: 01-test』的 LOCAL_MODULE := 01-test，

在下面加入 LOCAL_MODULE_TAGS := optional 即可

或是

有找到 LOCAL_MODULE_TAGS := user 的話

改成 LOCAL_MODULE_TAGS := optional
