ubuntu下linphone的編譯運行

    LinPhone是一個IP電話工具，運行於Linux下。它能夠讓你通過internet來查詢朋友的IP，並通過IP給他打電話。下面我會介紹如何在ubuntu下編譯運行linphone。

1.前提條件：

已經在ubuntu下配置好android開發環境，詳見http://blog.csdn.net/maylian7700/article/details/7538176#，這里不再贅述

2.然后使用git下載linphone-android在命令行里面輸入git clone git://git.linphone.org/linphone-android.git --recursive (--recursive一定要有，否則可能導致下載不完全）

3.查看README文件，發現需要android api至少為16，最好為19（否則的話會編譯錯誤），而且需要安裝一些必備的插件

              ****************************

COMPILATION INSTRUCTIONS
************************

To build liblinphone for Android, you must:
-------------------------------------------
0) download the Android sdk with platform-tools and tools updated to latest revision (at least API 16 is needed), then add both 'tools' and 'platform-tools' folders in your path.
1) download the Android ndk (=r10c) from google and add it to your path (no symlink !!!).
2) install yasm, nasm, curl, ant, rsync and the autotools: autoconf, automake, aclocal, libtoolize, pkgconfig
    On 64 bits linux systems you'll need the ia32-libs package
    With the latest Debian (multiarch), you need this:
        dpkg --add-architecture i386
        aptitude update
        aptitude install libstdc++6:i386 libgcc1:i386 zlib1g:i386 libncurses5:i386
3) run the Makefile script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
    $ make
4) (Optional) To install the generated apk into a plugged device, run
    $ make install
5) (Optional) To generate a liblinphone SDK zip containing a full jar and native libraries, run
    $ make liblinphone-android-sdk
6) (Optional) To generate a libmediastreamer2 SDK zip containing a full jar and native libraries, run
    $ make mediastreamer2-sdk
7) (Optional) To generate a signed apk to publish on the Google Play, run
    $ make release
It will ask you for the version number that will be displayed in the about page of the app.
Make sure you filled the ant.properties values for key.store and key.alias in order to correctly
sign the generated apk (it will ask you the password during the process)

To run the tutorials:
--------------------
1) open the res/values/non_localizable_custom.xml file and change the value of the show_tutorials_instead_of_app to true.
2) compile again using make && make install.
3) /!\ don't forget to put it back to false to run the linphone application normally. /!\

To create an apk with a different package name
----------------------------------------------
You need to edit the custom_rules.xml file:
1) look for the property named "linphone.package.name" and change it value accordingly
2) also update the values in the AndroidManifest file where the comment <!-- Change package ! --> appears
3) update the path to the sounds in the linphonerc-factory files in the res folders and optionally change default sip account on linphonerc-default
4) run again the Makefile script by calling "make"

To run the liblinphone test suite on android
--------------------------------------------
Simply run 
    $ make liblinphone_tester
This will be build everything, generate an apk, and install it on the connected device if any.

You can speed up the compilation by using ccache (compiler cache, see https://ccache.samba.org/). Simply export:
export NDK_CCACHE=ccache

TROUBLESHOOTING
***************
If you encounter the following issue:
E/dalvikvm( 2465): dlopen("/data/app-lib/org.linphone-1/liblinphone-armeabi-v7a.so") failed: Cannot load library: soinfo_relocate(linker.cpp:975): cannot locate symbol "rand" referenced by "liblinphone-armeabi-v7a.so"...
it's because you have installed the android-21 platform (which is chosen automatically because it's the most recent) and you deployed the apk on a android < 5 device. 
To fix this, in the Makefile, force ANDROID_MOST_RECENT_TARGET=android-19

If you encounter troubles with the make clean target and you are using the 8e android ndk, the solution can be found here: https://groups.google.com/forum/?fromgroups=#!topic/android-ndk/3wIbb-h3nDU

If you built the app using eclipse, ensure you ran at least once the make command (see above steps 0 to 3) ! Else you'll have this exceptions:
FATAL EXCEPTION: main
java.lang.ExceptionInInitializerError
...
Caused by: java.lang.UnsatisfiedLinkError: Couldn't load linphone-armeabi-v7a: findLibrary returned null
...

4.安裝所需插件

    sudo apt-get install yasm  
    sudo apt-get install nasm  
    sudo apt-get install curl  
    sudo apt-get install ant  
    sudo apt-get install autoconf  
    sudo apt-get install automake  
    sudo apt-get install aclocal  
    sudo apt-get install libtoolize  
    sudo apt-get install pkgconfig  

然而aclocal現在已經包括到automake里了，不需要安裝；libtoolize的安裝，正確的指令卻是: sudo apt-get install libtool
pkgconfig則為sudo apt-get install pkg-config。

5.修改linphone-android目錄權限，即chmod 777 linphone-android,進入目錄后執行make命令。可能會出現以下錯誤

Can't locate LWP/UserAgent.pm in @INC (@INC contains: /usr/lib64/perl5/site_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/5.8.8 /usr/lib/perl5/site_perl /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.8 /usr/lib/perl5/vendor_perl /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi /usr/lib/perl5/5.8.8 .) at hot_mover10.pl line 7.
BEGIN failed--compilation aborted at hot_mover10.pl line 7. 

通過終端輸入以下命令可以得以解決：

 perl -MCPAN -eshell 
cpan> install Bundle::LWP

6.再次make，其中過程如下

7.eclipse導入該工程，運行並真機調試，如圖所示：
