How to solve path problems?

March 12, 2013 - 4:15am #1

Hi,

 

I am new to Vuforia SDK development using Eclipse. I am trying to build ImageTargets project but facing severe path problems.

I have set path according to Vuforia configuration step 1,2,3.

 

I am facing problems in building native-code so in building .apk which crashes when about button is clicked.

 

Problem: #1

My Eclipse project builds .apk but crashes after About screen is clicked OK.

 

Problem: #2

$ ndk-build

Android NDK: ERROR:C:\Android\android-ndk-r8d-windows\android-ndk-r8d/jni/Androi d.mk:QCAR-prebuilt: LOCAL_SRC_FILES points to a missing file

Android NDK: Check that C:\Android\android-ndk-r8d-windows\android-ndk-r8d/jni/. ./../../build/lib/armeabi/libQCAR.so exists or that its path is correct

OK Thanks

My ndk-build problem gone.

I created dir structure on another PC and got results.

Now, my ImageTargets is compiling without any errors.

 

But, while running ImageTargets I am getting these errors like:

 

03-12 20:08:06.163: D/Zygote(33): Process 833 terminated by signal (4)
03-12 20:08:06.183: I/ActivityManager(96): Process com.qualcomm.QCARSamples.ImageTargets (pid 833) has died.

What must be the actual cause? How to fix it?

Please help

Hi,

if you installed the SDK and the samples with a directory structure similar to the one that I mention in my previous post, you should not need any change to the Android.mk file.

Hi,

 

Please give me one Android.mk with LOCAL_SRC_FILES having absolute path so I can try it again.

 

 

Thanks in advance

Hi,

Can Vuforia give services like suppling libImageTargets.so or available elsewhere on the website

No (note: that library will contain your sample code compiled, so if you later want to make any change to the sample code to build your own app, you will need to rebuild that library anyway)

Can I use libQCAR.so available in the C:\Android\vuforia-sdk-android-2-0-31\build\lib\armeabi-v7a folder?

Yes, but that will not sole your issue because you need to build the sample part too, so you really need to make the ndk-build work

This is a typical path on Windows:

 

C:\Development\Android\vuforia-sdk-android-2-0-30\
 
so, for Image Targets sample, the path is like:
 
C:\Development\Android\vuforia-sdk-android-2-0-30\samples\ImageTargets-2-0-6\
 
the main directories under the ImageTargets sample directory (like for any other samples) are:
  • \jni
  • \src
  • \res
  • \assets

Under \jni you will see:

  • Android.mk
  • Application.mk
  • CubeShaders.h
  • ImageTargets.cpp
  • SampleUtils.cpp
  • Teapot.h
  • Texture.cpp
  • Texture.h

There is no "Vuforia IDE", we recommend to use Eclipse though.

How to solve path problems?

March 12, 2013 - 11:40pm #3

Hi,

I am still strugling with path problems. again same error. I edited Android.mk according to forum post but no success.

 

1) Can you supply expected dir structure of Vuforia SDK from c:\

2) Names of files for ImageTargets sample project so that I can cross check for dir and files present in those dir.

3) Is Vuforia IDE available to bypass path problems of NDK build or any other tool or .batch like file to skip ndk-build?

 

Plz. help

 

Thanks in advance

Hi, Problem #1 and Problem #3 are just a consequence of Problem #2 (i.e. your ndk-build was not successfull...)

To solve Problem #2, you should check this thread which discusses the same issue:

https://developer.vuforia.com/forum/android/ndk-build-problem

Then problems #1 and #3 should disappear as well.

In addition, you can also check this article:
