You need to install the Android SDK and NDK

SDK: http://developer.android.com/sdk/index.html?utm_source=weibolife NDK: https://developer.android.com/tools/sdk/ndk/index.html (native lib)

Important: you have to set the path in the system. For Win 7 -> How to add android tools dir to windows 7 path?

If the path is not right you will get some errors like "Android NDK not found" ..

In the root folder from linphone you will find a readme. Follow the steps. Maybe you have to use linux or mac. I dont know if its work on Win 7 well.

Let me know if its worked.

  • Thanks for answering...i downloaded cygwin again with the autotools installed. and try to run source prepare_sources.sh in cygwing bash shell, then it shows the ./autogen.sh : No such file or directory – Kasun Wanniarachchi Feb 18 '14 at 06:00
  • Don't use prepare_sources.sh - it's deprecated. Use **make**. Be sure that you the the path to sdk and ndk. With **make install** you can install the linphone app on your device, and with **make linphone-sdk** you can create the library for use. – PiOsA Feb 18 '14 at 07:46
  • I used **make linphone-sdk** using my cygwin shell to the path of my linphone source cloned in git repository. but it give the error of **make: No rule to make target 'linphone-sdk'. Stop.**. SDK and NDK paths are already set in Environmental Variables, what would i do?? – Kasun Wanniarachchi Feb 19 '14 at 03:32
  • Did you run only **make** first? – PiOsA Feb 19 '14 at 15:30
  • i did that too... cursor blinks for few seconds and it gives me this error, **--/bin/sh: line 1: ./autogen.sh: No such file or directory --iLBC prepare stage failed --Makefile:18: recipe for target 'prepare-ilbc' failed --make: [prepare-ilbc] Error 1** – Kasun Wanniarachchi Feb 20 '14 at 04:44
  • That looks like that autogen isn't installed. Sry, i have no experience with Windows and Cygwin. Please check that the Packages from the top of the README are installed. – PiOsA Feb 20 '14 at 08:02

Failed to build linphone android source After few days of trying on windows7(using cygwin, autotools). But succeeded after using a MAC to build.

answer of this question has all the steps which required. Linphone for android is not working/missing libraries
