android make编译 no rule to make "xxx",need "xxx"-优快云博客

在编译Android源码时遇到'no rule to make'错误，提示缺少某个目标文件。问题可能源于mk文件配置错误。检查'need "xxx"'对应的文件是否已生成，并排查mk文件中预编译静态库的设定。修正mk文件，如将预编译的静态库libName和libName2改为使用BUILD_MULTI_PREBUILT构建。

编译安卓源码时遇到错误：no rule to make out/target/common/obj/JAVA_LIBRARIES/services_intermediates/class_debug.jar,

need out/target/common/obj/JAVA_LIBRARIES/libName_intermediates/libjava.jar

遇到类似错误可能是由mk文件出现错误。应首先check 相应need "xxx" 是否生成，然后需要check mk是否存在问题。

此问题方法：

修改前：

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := libName:jdk.jar \====>预编译jar实际未编译
libName2:rsa.jar

include $(BUILD_JAVA_LIBRARY)

include $(BUILD_DROIDDOC)

修改后：

include $(CLEAR_VARS)
LOCAL_STATIC_JAVA_LIBRARIES := libName \
libName2
LOCAL_SRC_FILES := \
            $(call all-subdir-java-files) \
        com/android/server/EventLogTags.logtags \
        com/android/server/am/EventLogTags.logtags

LOCAL_MODULE:= services

LOCAL_JAVA_LIBRARIES := android.policy telephony-common bouncycastle

include $(BUILD_JAVA_LIBRARY)

include $(BUILD_DROIDDOC)

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := libName:jdk.jar \
libName2:rsa.jar

include $(BUILD_MULTI_PREBUILT)   ===》添加预编译
