#Android ndk for linux how to#
The following example shows how to define a sysroot for a build targeting Android 5. Native APIs for the respective Android API levels reside under $NDK/platforms/ each API-level directory, in turn, contains subdirectories for the various CPUs and architectures. To define the sysroot, you must must know the Android API level you want to target for native support available native APIs vary by Android API level. The next thing you need to do is define your sysroot (A sysroot is a directory containing the system headers and libraries for your target). APP_ABI settings for different instruction sets. Each architecture corresponds to a different toolchain name, as Table 1 shows. You can use the toolchains provided with the Android NDK independently.īefore anything else, you need to decide which processing architecture your standalone toolchain is going to target. We are all set and the compiled executable is installed under $PROJECT/libs/ now. Compile thumb : foo libs/armeabi-v7a/foo We can also place it under a sub-directory of the top-level $NDK/apps/ directory.Įxample of using ndk-build, an Android.mk and an Application.mk with BUILD_EXECUTABLE:
The Application.mk also usually resides under $PROJECT/jni/. The Android.mk must resides in a subdirectory of your project’s $PROJECT/jni/ directory, and describes your sources and shared libraries to the build system. It can also override project-wide settings for specific modules. The Android.mk file is useful for defining project-wide settings that Application.mk, the build system, and your environment variables leave undefined. The Android.mk and the Application.mk files are really tiny GNU makefile fragments that the build system parses once or more. Use the ndk-build and an Android.mk with BUILD_EXECUTABLE Some of the examples are borrowed from there for the summary purpose.
Note: While writing this article, I found the official guide from Andriod was very nice and easy to read.
I have used Android NDK to compile shared libraries for Android, so I would like to summary the possible ways to compile an Android executable using Android NDK. The Android.mk build system has proven to be hard to maintain, as one needs a built Android tree to build against, and.
#Android ndk for linux drivers#
Since I have Android NDK installed on my Mac, I thought it would be nice if I can make good use of that. You can use the toolchains provided with the Android NDK independently, or as plug-ins with an existing IDE, such as Eclipse. Mesa hardware drivers can be built for Android one of two ways: built into the Android OS using the Android.mk build system on older versions of Android, or out-of-tree using the Meson build system and the Android NDK. The minimal, and recommended, NDK version to use is r19b: Go to ndk downloads page Windows users should create a virtual machine with an GNU Linux os installed, and then you can follow the described instructions from within your virtual machine.
