在android上使用 stand-alone toolchains移植 transmission

• we need to port openssl, curl , libevent first then we can port transmission.
• I install projects memtions above in my home directory : 

 

[dengwei @localhost ~]$ pwd

/home/dengwei

[dengwei @localhost ~]$ ls porting_*

porting_curl:

bin  include  lib  share

porting_libevent:

bin  include  lib  share

porting_openssl:

bin  include  lib  ssl

porting_transmission:

install    transmission 

• ./configure --host=arm-linux  --enable-cli --enable-daemon --prefix= " /home/dengwei/porting_transmission/install " CXX=arm-linux-androideabi-g++ CC=arm-linux-androideabi-gcc  --enable-gtk= no    LIBEVENT_CFLAGS= " -I /home/dengwei/porting_libevent/include/ -L/home/dengwei/porting_libevent/lib/ "  LIBCURL_CFLAGS= " -I /home/dengwei/porting_curl/include/ -L/home/dengwei/porting_curl/lib/ " OPENSSL_CFLAGS= " -I /home/dengwei/porting_openssl/include/ -L/home/dengwei/porting_openssl/lib/ "  LDFLAGS= " -L/home/dengwei/porting_libevent/lib/ -levent "

 

LDFLAGS

make && make install 

 

 

• error handling:

•               [dengwei 
               @localhost bin]$ file transmissioncli 
               
   transmissioncli: ELF  
               32-bit LSB executable, ARM, version  
               1 (SYSV), dynamically linked (uses shared libs), not stripped 
               
   [dengwei 
               @localhost bin]$ file transmission-daemon 
               
   transmission-daemon: ELF  
               32-bit LSB executable, ARM, version

   [dengwei 
               @localhost bin]$ pwd 
               
   /home/dengwei/porting_transmission/install/bin 
              

   dynamically linked, means we need .so file, so:

  ./adb  push ~/porting_transmission/install /data/

   

  in adb shell,use su and cat to copy file to  /system/lib which store .so file

 
           # 
            cat /data/lib/libevent-1.4.so.2 > ./libevent-1.4.so.2 
           
 cannot create ./libevent- 
           1.4.so. 
           2:  
           read-only file  
           system 
           
 
           # 
            su
 # adb remount 
           
 * daemon not running. starting it now on port  
           5038 * 
           
 * daemon started successfully * 
           
 
           
 remount succeeded 
           
 
           # 
             
          

  

            ./adb  
           push ~/porting_libevent/lib/libevent- 
           1.4.so. 
           2 /data/lib/ 
           
 ./adb  
           push ~/porting_curl/lib/libcurl.so. 
           5 /data/lib/ 
          

 in adb shell

# pwd

/system/lib 

#  cat /data/lib/libevent-1.4.so.2 > ./libevent-1.4.so.2
# cat /data/lib/libcurl.so.5 > ./libcurl.so.5

 

  in adb shell

 

 
           # 
            cat /data/lib/libcurl.so.5 > ./libcurl.so.5
 # /data/bin/transmission-daemon
 # ps 
           
 USER     PID   PPID  VSIZE  RSS     WCHAN    PC         NAME

           530    
           1      
           5424    
           984   ffffffff 40026c94 S /data/bin/transmission-daemon 
           
 
           # 
            /data/bin/transmission-daemon --version 
           
 Transmission  
           2.04 ( 
           11151) 
          

 

Finally, we still need to use a web visit way to confirm that transmission works all right.

first we need to set  TRANSMISSION_HOME (in order to find setting.json and locate torrent resume dir )
TRANSMISSION_WEB_HOME (in order to find web files) environment variables, otherwise we will get a 404 error

 

export TRANSMISSION_HOME=/data/transmission
export TRANSMISSION_WEB_HOME=/data/transmission/share/transmission/web

 

#ps 

  root       556     1       4400     1000   ffffffff 40026c94 S /data/bin/transmission-daemon

              

root      5724789003480000000040010458 R ps
# kill -9 556
# echo $TRANSMISSION_WEB_HOME
/data/share/transmission/web
# /data/bin/transmission-daemon -u root -v toor -w /sdcard/BT

start a webbrowser:http://127.0.0.1:9091 redirect http://127.0.0.1:9091/transmission/web

 

# /data/bin/transmission-remote --auth=root:toor -a /sdcard/Download/9203e0ebf3e5382dce42ca5add007a32bc0d9bcb.torrent

localhost:9091 responded: " success"

 Now , we can see a familar web interface of transmission web UI

 

 ==========================================

in real arm board instead of emulator, what we need to do :

 

1. mkdir /data/transmission/ 
2. mkdir /data/lib/
3. copy porting_transmission/install to board /data/transmission and make them executable by 
   running chmod 0777 ./* , in directory /data/transmission
4. copy 2 .so file to /data/lib/ 
5. su
6. #mount -o remount,rw /
7. #copy files in /data/lib/ to /system/lib/
8. #edit /init.rc by adding :
   export TRANSMISSION_HOME=/data/transmission
   export TRANSMISSION_WEB_HOME=/data/transmission/share/transmission/web
9. also we run 2 export command above
10. start transmission by /data/transmission/bin/transmission-daemon -u root -v toor -w /sdcard/BT
11. /data/bin/transmission-remote --auth=root:toor -a /sdcard/Download/9203e0ebf3e5382dce42ca5add007a32bc0d9bcb.torrent
    localhost:9091 responded: "success"

 

Now , transmission begin to download the job task.
