如何提取Android NDK包？

Question

我的操作系统是CentOS 32位.

我想用7-zip解压缩包,用rpm安装7-zip而不会出错.但是当我提取NDK包时,它不起作用.像这样:

[root@localhost ~]# ls
anaconda-ks.cfg                 jni-test
android-ndk-r10e-linux-x86.bin  p7zip-9.20.1-1.el5.rf.i386.rpm
install.log                     p7zip-plugins-9.20.1-1.el5.rf.i386.rpm
install.log.syslog
[root@localhost ~]# 7z x android-ndk-r10e-linux-x86.bin

Processing archive: android-ndk-r10e-linux-x86.bin

Error: Can not open file as archive

根据谷歌的官方文件操作:

[root@localhost ~]# ll
??? 307344

为什么？

更新: 此问题的原因是MD5值不相同.

如果是7zip格式包,可以用7zip解压缩.但事实并非如此,您可以从file命令中看到格式.

$ file android-ndk-r10e-linux-x86_64.bin 
android-ndk-r10e-linux-x86_64.bin: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=8c7de897dd2f5d869d108bed2f2152a68b2f7b0a, stripped

从上面的输出结果中,我们可以看到它是一个ELF可执行文件,所以只需添加可执行位并执行它.

$ chmod u+x android-ndk-r10e-linux-x86_64.bin
$ ./android-ndk-r10e-linux-x86_64.bin

它将解压缩到android-ndk-r10e当前目录下的目录.
