gcc on rooted android 4.1.2

我下载了

http://rwiki.sciviews.org/doku.php?id=getting-started:installation:android

并在/ data中创建/ data / local / gcc,将前两个文件放入其中并将其用完。

然后我修改了文件/ system / etc / mkshrc以使其执行此操作:

export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH:/ data / local / gcc / lib export PATH = $ PATH:/ data / local / gcc / bin

建议如上。然后我创建了一个test1.c文件

#include <stdio.h>
int main()
{
printf("Hello")
return 0;
}

并使用命令

编译它
gcc test1.c -o test1

然后执行命令

./test1

结果:

“无法执行:权限被拒绝”。 test1上的ls -l给了我-rw-rw-r-- root(因为我已经创建了它作为root;但我做的都不是root,同样的“Permission denied”结果)。然后我尝试使用chmod使其可执行,但没有任何成功。你有什么想法吗?

很多

看起来你的编译程序在/ sdcard /中。 / sdcard /很可能是FAT文件系统,因此chmod + x不起作用。你必须将它放在/ system /中(注意:/ system /以只读方式挂载)。

我在运行CyanogenMod的GS3上尝试了同样的操作并将它放在/ system /中为我工作。
