Building Pango Cairo for Android NDK

I found someone who ported Pango Cairo for Android NDK ( blog post , source code ). However, I was not successful in compiling my sample project. Has anyone managed to do this and can tell me what I'm doing wrong?

This is what I have tried so far:

  • git clone --recursive http://dev.laptop.org/git/users/cscott/android-libs/
  • git for some reason could not find pixman, so git clone http://cgit.freedesktop.org/pixman/ , and moved to android-libs / jni / pixman
  • copied the contents of android-libs / jni / to android-libs / examples / java-bitmap / jni (don’t know which Android.mk to save?)
  • renamed java-bitmap / jni / Makefile.devel to Makefile
  • edited the java-bitmap / jni / Makefile as follows: NDK = / cygdrive / f / android-ndk-r8b ToolChain = $ (NDK) /toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin
  • tried to run make in java-bitmap / jni

I get the following error:

Here is a fragment of config.h file

I took it one step further.

Instead

 git clone http://cgit.freedesktop.org/pixman/

I downloaded using

 git clone --recursive http://dev.laptop.org/git/users/cscott/android-pixman

and copied all the files to the empty jni/pixman . Now the pixman-elf-fix.h found, but the linker does not work:

/tmp/cc2XOCMj.o :(. ARM.exidx.text.main + 0x0): undefined reference to `__aeabi_unwind_cpp_pr0 '.

But this is probably caused by the same problem.
