I'm trying to compile openssl with cast support but I instead get this error:

I'm probably missing something very trivial here, since I'm new to Android and C in general, so be nice :)
EDIT: I saw that there is a Makefile for cast. I'm guessing there is a whole load of linking magic going on at the very bottom of the original Makefile. How would I do something equivalent for Android?

I am using this to build ffmpeg on ndk:
roman10's android ndk r9d - ffmpeg tutorial
The link shows how to compile, but its not clear how to use it. Can anybody guide me? Thanks.
After ndk-build from my project root i was able to generate .so files inside libs/armeabi and obj/local/armeabi.. Now I am getting findLibrary returned null?? What to do now?

LOCAL_MODULE:= avutil # libavutil.so
example (used to work):
https://github.com/18446744073709551615/reDroid/blob/master/jni/Android.mk
UPDATE:
Once again: you do not need the lib prefixes in library names; LOCAL_MODULE:= avutil will give you libavutil.so
At second, what parameter do you pass to loadLibrary()? Again, it should be "avutil" for libavutil.so.
If you have problems, the best way is to start with the hello-jni example in the NDK (your-ndk-dir/samples/hello-jni/)
/* this is used to load the 'hello-jni' library on application
* startup. The library has already been unpacked into
* /data/data/com.example.hellojni/lib/libhello-jni.so <== !!!!!!!!!!!!!
* at installation time by the package manager.
*/
static {
System.loadLibrary("hello-jni");
}
Once the example compiles and runs, you may add your libraries to it and have your stuff work.
You use name libavutil to refer to libavutil-54.so during ndk-build. This is fine, but the runtime lib is still called libavutil-54.so. Moreover, your other modules, including tutorial01, know it by this name, so renaming it in libs/armeabi will also be wrong.
You need something like
static {
System.loadLibrary("avutil-54");
System.loadLibrary("avcodec-56");
System.loadLibrary("avformat-56");
System.loadLibrary("swscale-3");
System.loadLibrary("tutorial01");
}
In recent version of Android, the system will automatically resolve the local external references, so it's enough to call
static {
System.loadLibrary("tutorial01");
}
Replace your
LOCAL_SHARED_LIBRARIES := avformat avcodec swscale avutil
with
LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil libavfilter libswresample
in Android.mk in your Jni folder.
And Load the libraries like below
static {
System.loadLibrary("avutil-54");
System.loadLibrary("avcodec-56");
System.loadLibrary("avformat-56");
System.loadLibrary("swscale-3");
System.loadLibrary("avfilter-5");
System.loadLibrary("swresample-1");
System.loadLibrary("tutorial01");
}
Are you sure that you are using a phone with an armeabi processor? Add the armeabiv7 in the Application.mk file and it will compile the required files for armeabiv7 phones in the libs folder.
APP_ABI := armeabi armeabi-v7a x86
This should work.

And i in java code i add:
static
{
System.loadLibrary("start-spice");
}
Would be really really gratefull if someone helped!
If you have the prebuilt static library for Android in $(LOCAL_PATH)/libxml2/libxml2.a, you can use it as is in your spice-android project,
LOCAL_STATIC_LIBRARIES += xml2
Instead of include $(BUILD_SHARED_LIBRARY) for xml2, use
LOCAL_SRC_FILES := libxml2/libxml2.a
include $(PREBUILT_STATIC_LIBRARY)
If you have a strong reason to use xml2 as a separate shared library, you need to add call
System.loadLibrary("xml2");
to your Java code (before loading libspice-android.so) and replace LOCAL_SRC_FILES := $(LOCAL_PATH)/libxml2/libxml2.a with
LOCAL_WHOLE_STATIC_LIBRARIES := $(LOCAL_PATH)/libxml2/libxml2.a
This is issue of linking shared libraries, you need to add LOCAL_LDLIBS += $(LIB_PATH) -lxm2 just before LOCAL_SHARED_LIBRARIES= xml2 .
i've successfully cross compiled a c++ library to the android plateform using the android ndk standalone toolchain.
i've created a new android application project into Eclipse with a jni dolder and Android.mk file and when i do an ndk-build the building goes well and it adds mylib.so to libs/armeabi folder
The problem is when i do a System.loadLibrary("mylibname");
i get the following error in the logcat:
Unable to dlopen(/data/data/com.oussama.firsttry/lib/libdash.so): Cannot load library: link_image[1995]: failed to link libdash.so
that cause a java.lang.UnsatisfiedLinkError: my lib not found**.
There must be a library that my lib depends on and the emulator can't load it so i've done a readelf -d mylib.so and here is the result:

I would be thankfull if any one can help me.
You should use the system versions of libm, libc and libdl shared libraries,
LOCAL_LDLIBS := -lm -ldl
If you can't, link them statically.
