(out/target/product/generic/obj/EXECUTABLES/helloworld_intermediates/LINKED/helloworld)

target Non-prelinked: helloworld (out/target/product/generic/symbols/system/bin/helloworld)

target Strip: helloworld (out/target/product/generic/obj/EXECUTABLES/helloworld_intermediates/helloworld)

Install: out/target/product/generic/system/bin/helloworld

5.如上面的编译结果所示,编译后的可执行文件存放在out/target/product/generic/system/bin/helloworld,通过”adb push”将它传送到模拟器上,再通过”adb shell”登录到模拟器终端,就可以执行了

============================================

上一篇中(即《Android编译环境(1) - 编译Native C的helloworld模块》),我们试用了通过标准的Android.mk文件来编译C模块,下面我们来试试如何直接运用gcc命令行来编译,从而了解Android编译环境的细节。

Android编译环境提供了”showcommands”选项来显示编译命令行,我们可以通过打开这个选项来查看一些编译时的细节。当然,在这之前要把上一篇中的helloworld模块clean:

# make clean-helloworld

上面的“make clean-$(LOCAL_MODULE)”是Android编译环境提供的make clean的方式。

接下来使用showcommands选项重新编译helloworld:

# make helloworld showcommands

build/core/product_config.mk:229: WARNING: adding test OTA key

target thumb C: helloworld <= development/hello/hello.c
