Fail to build glmark2 by ndk for an Android 3.1 tablet

Hmm, can you check if there actually is an android/jni/src/canvas-android.cpp file?

The glmark2 tarball uses symbolic links internally. One guess is that if you extracted the tarball in Windows, the symbolic links where not handled properly. Can you try extracting through cygwin (tar xzf glmark2-2011.08.tar.gz), and see if that changes things?

hi Alex
unzipped the tarball by command do change something.
Now, the return error message becomes
=====================================================================
$ ndk-build
Compile++ thumb : glmark2-android <= android.cpp
arm-linux-androideabi-g++.exe: jni/src/android.cpp: No such file or directory
arm-linux-androideabi-g++.exe: no input files

js/glmark2-android/src/android.o] Error 1
=====================================================================

Below is the file tree after extracted.
the /jni/src/ is a link to redirect the reference path to the real source path(i.e. /glmark2-2011.08/src/)
However, it seems not workable to re-directory the path to get the source file.

I just checked the android.cpp is existed in /glmark2-2011.08/src/ (check below from my console)
does the mk file written properly to re-directory the path when looking for cpp files?
=====================================================================

Does "ls android/jni/src" show the correct files?

You can try replacing the symbolic links android/jni/src and android/assets with copies of the linked-to directories to see if this solves the problem. This is of course a hacky solution, but it will at least allow you to move forward and also find out if symbolic links are the culprits here.

Yes, the "ls android/jni/src" commands shows those source file under /glmark2-2011.08/src/ : )

I just copy the src folder to the path "/android/jni/" and compiler is passed, I am moving forward! (let me know if my workaround is incorrect : p )

I am trying to continue building the package from the command line as below (from INSTALL.android):
$ android update project -p . -s
$ ant debug {or release}

thanks a lot!

Thanks Alexandros Frantzis, that solved my question.
