ubuntu14.04(32位)下编译android4.4时遇到的问题

来源：互联网发布：用友网络未来价值2017 编辑：程序博客网时间：2024/05/22 10:59

我的系统是ubuntu14.04(32位),安卓系统源码是android4.4

1.解决：prebuilts/tools/gcc-sdk/../../gcc/linux-x86/host/x86_64-linux-glibc2.7-4.6/bin/x86_64-linux-aronly run on 64-bit linux

make: ***[out/host/linux-x86/obj/STATIC_LIBRARIES/libinput_intermediates/libinput.a]Error 1

原因：安装的ubuntu系统为32位，而android源代码系统的支持64位系统下编译

参考网站https://ntu-android-2014.hackpad.com/ep/pad/static/TDe6S3SaWKN

/home/hsc/usr/Android/是我存放Android4.4的源代码文件夹

根据错误提示: cd/home/hsc/usr/Android/prebuilts/tools/gcc-sdk/

然后把gcc文件下的第23到第39行注释掉，除38行外。

2.也有可能遇到系统位数不匹配

操作：更改Android源代码文件夹下的external/qemu/Makefile.target和Makefile.common文件

external/qemu/Makefile.target

252 line,

LOCAL_CFLAGS +=$(common_LOCAL_CFLAGS) -m64

换成

ifneq($(BUILD_HOST_64bit),)

LOCAL_CFLAGS +=$(common_LOCAL_CFLAGS) -m64

else

LOCAL_CFLAGS +=$(common_LOCAL_CFLAGS) -m32

endif

446 line,
