LinPhone building process for Android

Question

I am building Linphone application for android. I am working in Ubuntu 11.04 OS.

I Followed the steps given in README file:

1. Download the Android ndk (>=r5c) from google.
2. Install the autotools: autoconf, automake, aclocal, libtoolize pkgconfig

3. Run the ./prepare_sources.sh script in the top level directory. This will download iLBC source files and convert some assembly files in VP8 project.
   $ ./prepare_sources.sh

4. Finally from directory linphone-android, just execute command:
   $ ${my google ndk directory}/ndk-build

I got the output in terminal as

StaticLibrary  : libopencoreamr.a 
Compile arm    : vpx <= vpx_mem.c 
In file included from jni/..//submodules/externals/build/libvpx/../../libvpx/vpx_mem/vpx_mem.c:18: 

jni/..//submodules/externals/build/libvpx/../../libvpx/vpx_mem/include/vpx_mem_intrnl.h:14:24: error: vpx_config.h: No such file or directory 
make: *** [obj/local/armeabi-v7a/objs/vpx/vpx_mem/vpx_mem.o] Error 1 

If i solve this error i will be able to compile and run the Linphone application. Some one please help me to solve this..

Answer 1

1. Open terminal
2. Download source code through command: git clone git://git.linphone.org/linphone-android.git --recursive
3. Go to root directory of the downloaded project through command: cd /home/your_downloaded_project_path/
4. Fire the command: ./prepare_sources.sh /home/android-ndk-r7b/
5. Go to root directory of NDK folder through command: cd /home/android-ndk-r7b/
6. Fire the command: export NDK_PROJECT_PATH=/home/your_downloaded_project_path/
7. ./ndk_build clean
8. ./ndk_build -i

Note: Here /home/android-ndk-r7b/ will be your NDK path where you have stored downloaded NDK

Try dis..if still not work mention error what you would get.

Answer 2

You have to specify the complete path the ndk when executing prepare_sources

$./prepare_sources.sh /complete/path/to/android-ndk

If you only specify the relative path to the ndk, it'll also throw the same error.

Then, you can call 'ndk-build', 'ant debug',... whatever you want to.
