Where is .so file generated for hello-jni ?

[swapnil kamble]

Hi,
    I am trying to build ndk samples by following command. It gives me compilation successful, but I could not find libhello-jni.so file even if libs directory. And even if add new directory as per given in this tutorial

http://earlence.blogspot.com/2009/07/writing-applications-using-android-ndk.html

$make APP does not find this app, says use hello-jni or two-libs.

bash-3.2$ make APP=hello-jni -B
Android NDK: Building for application 'hello-jni'
Compile thumb  : hello-jni <= sources/samples/hello-jni/hello-jni.c
SharedLibrary  : libhello-jni.so
Install        : libhello-jni.so => apps/hello-jni/project/libs/armeabi
bash-3.2$

Thanks in advance..

To compile 'hello-jni', while you are in the root folder of you NDK (say 'NdkRoot'), type- "make APP=hello-jni". It works fine.
('hello-jni' is a variable name corresponding to the folder name in "NdkRoot/apps")
Your generated .so file "libhello-jni.so" is found in-
NdkRoot/apps/hello-jni/project/libs/armeabi/

P.S. You can open the 'project' folder in eclipse

good luck

Hello

> Install : libhello-jni.so => apps/hello-jni/project/libs/armeabi

As the compiler says, the libhello-jni.so is copied to [NDK_ROOT/]apps/
hello-jni/project/libs/armeabi

Moreover, the folder names for your project in NDK_ROOT/source and
NDK_ROOT/apps need to be identical (not "native" and "NativeApp" as in
your case). Also, folder names are case sensitive.

Thanks Rajat and Shuhrat for your replies. I got it working.

One more basic question that if I have shared lib using other shared lib, then do I need to re-compile that other shared lib too ?

Thanks again.

A shared library is a library which can be used by more than one program. Most shared library systems are restricted in that they only allow a single level of dependencies. If a shared library would try to compile making use of another one, it might create some problems. Although, you can check 'Libtool', which is used for inter-library dependencies, but shared library depending on another one is mostly not recommended.
