I have found a couple of success stories here and here , but I can't say the same about me. I am specifically trying to use the library in this link , as well as the boost thread library. In the code below, I am only trying to include the thread library, not the math library. The process I used to build the boost libraries is pretty much the same as the first link I attached. So far, it seems I have successfully built the boost libraries, but when I run ndk

The application does use multiple threads, but supposedly r5 of the ndk supports multiple threads. Also, I'm not even getting to the point where gdb starts up. I run the command: ndk-gdb --start --force --verbose It then finds the proper path for the ndk and sdk (or at least adb), and the needed ABIs and whatnot. $ ndk-gdb --start --force --verbose Android NDK installation path: /home/leif/eclipse/android-ndk-r5b Using default adb command: /home/leif/eclipse/android-sdk

Trying to run the project I get this Error:Execution failed for task ':app:compileDebugNdk'. > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'ndk/ndk-build'' finished with non-zero exit value 2 So first of all for me it's weird to see this error, because working in Eclipse Android SDK before, I ran ndk-build by myself which I still do. So is Android Studio running ndk

The same comments for eglCreateImageKHR and glEGLImageTargetTexture2DOES. I have added EGL/eglext.h and GLES2/gl2ext.h . I tried to include ui/GraphicBuffer.h but it is not taking it. Is there another header file to be added ? The code given below I have added to avoid use of glTexSubImage2D(

I read this page and wondering if this is true The same is possible with POSIX popen() but it is not currently supported by bionic, so you can't use that in Android JNI. Instead you can probably use the system() and pipe the output to a file and then read that file afterwards. Looks like the Java approach will be cleaner if you will be doing the rendering in Java. But I also read someone suggesting to use popen. I also tried it myself but sometime my app crashes and I dont know why. Is popen safe to use

Please define HOST_AWK to point to Gawk or Nawk !" error on latest android ndk revision 7. 回答1: Solved the problem. Solution: Navigate to ../android-ndk-r7/prebuilt/linux-x86/bin Rename the file awk to awk_ Imoprtant thing to note on windows machine: ndk revision 7 onwards, ndk source can be built without cygwin, ie.., instead of calling ndk-build command from inside a Cygwin shell, you should call run ndk-build.cmd inside a MSDOS command window. It works because probably ndk-build
