I have always worked with Visual C/C++ IDE, so i am really new to GCC, makefiles and so on. By default, the Android NDK build process for Android applications using JNI creates a version of your. ![]() I have found a lot of similar questions over the internet. I forgot to mention that i run ndk-buld under the jni directory of the helloworld project. Linking Vanadium (Chromium) and the Linux kernel with LTO + CFI are the most. Ws/bin/./lib/gcc/arm-linux-androideabi/4.4.3/././././arm-linux-androideabi/ Update server Stable release manifest Standalone SDK Android Studio. If i do not remove references to mylib, it compiles but doens't link: i obtain the following result:ĭ:/android/android-ndk-r6b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windo If i remove every reference to mylib from ndkfoo.cpp, it compiles and run even on my phone. This allows using definitions from newer headers, while only linking to such functions dynamically (e.g. Unfortunately, this doesn't seems to work. (therefore, the path to libmylib.so is: d:/android/workspace/mylib/libs/armeabi). My directories are organized in the following way: d:/android/android-ndk-r6b => android ndk rootĭ:/android/workspace/helloworld => helloworld projectĭ:/android/workspace/mylib => mylib project library NDK r19 turns libgcc.a into a linker script to ensure that libunwind.a is linked before libgcc.a, which clears up most of the issues. LOCAL_LDLIBS += -L$(LOCAL_PATH)/././mylib/libs/armeabi/ -lmylib Since the issue with broken prebuilts can only be fixed by the build system, the NDK cannot do any more to solve that problem. cd Guarantee that you are under the '/Home' directory, works for Ubuntu at least, for other systems 'cd /Home' may work. Once profile is configured, you should see the following. Open a terminal and type as follows (noted that you need you change the ndk path according to your download and location): 1. The only way you have to configure is ANDROIDNDKROOT which is a path to the Android NDK installation. Suppose the library file is libmylib.so, i have the following android.mk script: Add linking your libraries in native-lib cmake: targetlinklibraries(native-lib gdriver udev) This is just an example, you can implement it however you want, for example without native-lib at all, but main point is to recompile your executable like library and call its entry function from Activity (in our case via JNI). First we need to let the system to know where to find ndk-build. Now, in the helloworld Android.mk, i need to make some edits in order to tell the linker to include that library. At the end of the compilation, i obtain a. cpp file called ndkfoo.cpp) sample, i created a new Android project in Eclipse (updated for Android), added a jni directory, added a Android.mk and Application.mk files, edited them in order to compile the. Since i have a library written in C++ that i wish to use in the hello-jni (actually, i have created a prj called helloworld with a single. I am modifying the hello-jni sample in order to learn working with NDK. ![]()
