Thanks Reynaldo for the reply , but i have already copied all the .so's in the given path. Is NDK HOME is the location of installed (copied from android developer site) NDK or is it inside the downloded android source code for 2.3.4_r1. "Android headers for your target device's OS version. We are bundling 2.3.3_r1 headers but you are welcome to try with other versions and report back your results. This is a requirement for building the flingersinks". where we are using the android headers? Is it necessary to use android headers to build gstreamer using NDK .How to include them? previosly i was getting error StaticLibrary : libstdc++.a SharedLibrary : libgstaudioflinger.so /path/to/gstreamer-proj/ ndk/android-ndk-r6b/<div id=":cj">toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld: cannot find -lmedia collect2: ld returned 1 exit status make: *** [<path/to/gstreamer_ndk_bundle>/obj/local/armeabi/libgstaudioflinger.so] Error 1 </div> which i have resolved by making a soft link for libmedia.so -> ../../../../../platforms/android-3/arch-arm/usr/lib/libmedia.so. But now i am getting another error ndk/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld: warning: cannot find entry symbol xport-symbols-regex; defaulting to 00004198 Install : libgstaudioconvert.so => libs/armeabi/libgstaudioconvert.so Compile arm : gstaudioflinger <= gstaudioflingersink.c Compile++ arm : gstaudioflinger <= GstAndroid.cpp cc1plus: warning: command line option "-Wdeclaration-after-statement" is valid for C/ObjC but not for C++ SharedLibrary : libgstaudioflinger.so /path/to/gstreamer-proj/ndk/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/../lib/gcc/arm-linux-androideabi/4.4.3/../../../../arm-linux-androideabi/bin/ld: cannot find -lutils collect2: ld returned 1 exit status make: *** [/home/saurabh/gstreamer-proj/gstreamer-bundle/gstreamer_ndk_bundle/obj/local/armeabi/libgstaudioflinger.so] Error 1 please help me in resolving this issue. regards saurabh dixit
