I am trying to compile android-NDK project which uses L2CAP Bluetooth profile.When I compile in eclipse with android-ndk-r8d-windows and android-sdk-4.2 I am getting following error
arm-linux-androideabi-g++: error: libbluetooth.so: No such file or directory
make: *** [obj/local/armeabi/libl2cap_BTComm.so] Error 1
Please help me in solving this
I got the same problem in Ubuntu 12.04 while building the ndk project using ndk-build.
The problem is the missing g++ compiler. After install a GNU C++ compiler it works now.
Interestingly, when I recompile the whole project from fresh it got the same complain again.
(before I was using cygwin and ubuntu to compile the same project and it was working)
Its been over a year now since the last reply but I think the answer is to use the -l option of g++ to add the directory with the lib to g++'s search paths.

I was trying to compile Magisk in android studio and it had told me to use the build.py file to build the binarys and so I did.
Except I get this error ALL THE TIME!
Building binaries: magisk magiskinit magiskboot busybox
fcntl(): Bad file descriptor
C:/Users/(name)/AppData/Local/Android/Sdk/ndk/magisk/build//../build/core/build-binary.mk:654: Android NDK: Module magisk depends on undefined modules: cxx
Anyway to fix this?
I did install Cmake for windows and I still can't figure out what cxx might be
The Magisk GitHub repository is, in fact, multiple repositories composed. To download all of them you need to:
git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git
This is mentioned in the readme.md as well as on the GitHub main page: https://github.com/topjohnwu/Magisk
I am trying to compile shell script that compiles the C project library, but i am stuck at this when it comes to compile the nmake part.
I am using NDK 21 and cmake version is 3.10
I am using shell script using bash same as defined here, i want to compress this library as they showing in the docs running ./android.sh

here is the attached log:

You should use Linux Make, not NMake. Generally speaking, these scripts were never tuned to run on Windows, in cygwin or mingw shell, even though I have run them in WSL (Ubuntu) bash.
A lot of people have mentioned about compiling ffmpeg for android. But I recently tried many of them and did not find them working.
Here is what I tried.
https://github.com/guardianproject/android-ffmpeg-java
but in this I got the following errors.
/home/musil/Desktop/android-ndk-r10c-linux-x86_64/android-ndk-r10c/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc --sysroot=/home/musil/Desktop/android-ndk-r10c-linux-x86_64/android-ndk-r10c/platforms/android-3/arch-arm -I../x264 -mfloat-abi=softfp -mfpu=neon -mcpu=cortex-a8 -c -o /tmp/ffconf.6LOSva5W.o /tmp/ffconf.YWZ9ftQ8.c
arm-linux-androideabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
C compiler test failed.
Than I have tried other way mentioned on
http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/
but in that I got the following error.
But in that the prefix install is /usr/local/ instead of ./arm/ and arch is x86 instead of arm. And it compiles but no arm folder is created.
Does anyone know how to compile ffmpeg for ndk-r10c.
Will be very helpful if someone can point out what I am doing wrong or how can I build the ffmpeg 2.4.1 for latest ndk.
Thanks
I am not sure why you see that error. I was able to successfully compile FFMpeg and you should be able to get the .so files for all architecture from this link https://github.com/android-native-libraries
Hi I have been working for weeks to compile ffmpeg library on Windows platform.But I found no way so far.Is it there any way to compile ffmpeg library on Windows 7.
I am using Cygwin on Windows.
Whenever I try to do ndk-build I get this message.
Android NDK: ERROR:jni/yuv2rgb/Android.mk:ffmpeg-prebuilt: LOCAL_SRC_FILES points to a missing file
Android NDK: Check that jni/ffmpeg-build/armeabi/libffmpeg.so exists or that its path is correct
/cygdrive/D/AndroidNDK/android-ndk-r8c/build/core/prebuilt-library.mk:43: *** Android NDK: Aborting . Stop.
& while searching for solution of this error I found that I will have to compile the libraries first.For compiling by using ./build_android.sh. I got this error message.
./build_android.sh
./build_android.sh: line 72: ./configure: No such file or directory
Please please guide me what should I do.
I'm starting to use the android ndk (r8c), and for that I have installed a fresh version of Ubuntu 12.10 (32bit)
Problem, whatever I try to build, I got freaky errors that drive me crazy...
~/workspace/Test$ ndk-build
Compile thumb : Test <= Test.c
SharedLibrary : libTest.so arm-linux-androideabi-g++: error:
./obj/local/armeabi/objs/Test/Test.o: No such file or directory make:
* [obj/local/armeabi/libTest.so] Error 1
So here, I try to run ndk-build on a simple hello world in jni. I can't understand the problem, as I thought the ndk-build command was suppose to create Test.o itself...
So I tried the same thing with ndk-r7 (we never know), and it is even uglier...
~/workspace/Test$ ~/Code/android-ndk-r7/ndk-build
Compile thumb :
Test <= Test.c Messages de l'assembleur: Erreur fatale: option -march=
invalide: « armv5te » make: * [obj/local/armeabi/objs/Test/Test.o]
Erreur 1
I can't find any answer that seems to help. (I've also tried to build hello-jni sample the same way, but the output was the same.
Please, someone save my hair... Hope I've been clear enough.
So I decided to reinstall my ubuntu, and it worked well this time.
I still have no idea why it didn't the first time, as I think I have done exactly the same manipulation (I went to Ubuntu 12.04 instead of 12.10 though).
