-
first : download arm cross compliers
-
next : modify env
[dengwei@localhost ~]$ vi ~/.bashrc
export PATH="/home/dengwei/arm-marvell-linux-gnueabi/bin:$PATH" -
third: code here#include <stdio.h>
#include <stdlib.h>
#include < string.h>
int main( int argc, char** argv) {
printf( " hello world\n ");
FILE *pfd = fopen( " /mnt/sdcard/345 ", " a+ ");
fwrite( " abcedfg ", sizeof( char), strlen( " abcdefg "),pfd);
fclose(pfd);
return 0;}
-
fourth: compile: arm-marvel-linux-gnueabi-gcc -static hi.c -o hi123
-
fifth: usage of adb
adb push ~/hi123 /data
adb shell # /data/hi123
hello world
# pwd
/mnt/sdcard
# cat 345
abcedfg#
if you intend to use cpp file , just : mv hi123.c hi.
if you meet " Read-only file system " error, pls do the following:
mount -o remount,rw /
when I put the executable file to real mobile phone , excuted it by console by emulator
#/sdcard/hi1234,I encount a error: Permission denied. It works now after I #chmod u+x /sdcard/hi1234 # mv /sdcard/hi1234 /system/sbin/
