我下载了
https://www.dropbox.com/s/uammywfed6d2rgj/android_gcc_r2a.tar.bz2
和
https://www.dropbox.com/s/uammywfed6d2rgj/android_gcc_supplement.tar.bz2
从
http://rwiki.sciviews.org/doku.php?id=getting-started:installation:android
并在/data 中创建/data/local/gcc，将之前的两个文件放入其中并使用它们。
然后我修改了文件 /system/etc/mkshrc 使它这样做：
导出 LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/local/gcc/lib 导出 PATH=$PATH:/data/local/gcc/bin
按照建议。然后我创建了一个 test1.c 文件
#include <stdio.h>
int main()
{
printf("Hello")
return 0;
}
并用命令编译它
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 （因为我已经将它创建为 root ；但我并没有成为 root 以及相同的“权限被拒绝”结果）。然后我尝试了一个 chmod 使其可执行，但没有成功。你有什么主意吗 ？
多谢
