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 1 (SYSV), dynamically linked (uses shared libs), not stripped
  
       [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

root      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.
