在编译Android的HAL模块时遇到如下问题：
[root@OUC-B103 modules]# mmm led/
============================================
PLATFORM_VERSION_CODENAME=REL
PLATFORM_VERSION=2.3.4
TARGET_PRODUCT=generic
TARGET_BUILD_VARIANT=eng
TARGET_SIMULATOR=
TARGET_BUILD_TYPE=release
TARGET_BUILD_APPS=
TARGET_ARCH=arm
HOST_ARCH=x86
HOST_OS=linux
HOST_BUILD_TYPE=release
BUILD_ID=GRJ22
============================================
make: 进入目录“/tmp/android/Android-2.3.4”
make: *** 没有规则可以创建“out/target/product/generic/obj/SHARED_LIBRARIES/led.default_intermediates/LINKED/led.default.so”需要的目标“out/target/product/generic/obj/lib/liblog.so”。 停止。
make: 离开目录“/tmp/android/Android-2.3.4”
我在网上查找，都没找到解决办法，提示说需要的目标“out/target/product/generic/obj/lib/liblog.so”但是obj下没有lib文件。请大家帮忙看看，问题在哪里，谢谢了！

必须先完整编译一次，然后才能单独用mmm编译某个模块

我是完整编译后才用的mmm命令,那我的obj下没有lib文件是什么原因呢？是完整编译过程有问题么？求教

我的编译有这个文件啊，上传送你一个，你放到那目录看编译过不

我有同样的问题，楼上或谁可以帮下我吗？

希望这个帖子对你有帮助
