Lastly, on Windows, the native-image builder will only work when it is executed from the 圆4 Native Tools Command Prompt. You can use Visual Studio 2017 version 15.9 or later. * Install Visual Studio with the Windows 10 SDK * Install the Visual Studio Build Tools with the Windows 10 SDK To start using Native Image on Windows, install Visual Studio and Microsoft Visual C++ (MSVC). Prerequisites for Using Native Image on Windows On macOS use xcode: xcode-select -install On other Linux distributions use dnf package manager: sudo dnf install gcc glibc-devel zlib-devel libstdc++-static On Ubuntu Linux use apt-get package manager: sudo apt-get install build-essential libz-dev zlib1g-dev You can still install libstdc++-static as long as the optional repositories are enabled ( ol7_optional_latest on Oracle Linux 7 and ol8_codeready_builder on Oracle Linux 8). On Oracle Linux use yum package manager: sudo yum install gcc glibc-devel zlib-devel Some Linux distributions may additionally require libstdc++-static. Install glibc-devel, zlib-devel (header files for the C library and zlib) and gcc, using a package manager available on your OS. The above command will install Native Image from the GitHub catalog for GraalVM Community users.įor GraalVM Enterprise users, the manual installation is required.įor compilation native-image depends on the local toolchain. Run this command to install Native Image: gu install native-imageĪfter this additional step, the native-image executable will become available in Native Image can be added to GraalVM with the GraalVM Updater tool. Native Image for GraalVM Enterprise Edition is available as an Early Adopter feature.Įarly Adopter features are subject to ongoing development, testing, and modification.įor more information, check the Oracle Technology Network License Agreement for GraalVM Enterprise Edition. Native Image for GraalVM Community Edition is licensed under the GPL 2 with Classpath Exception. The Native Image technology is distributed as a separate installable to GraalVM. To inform native-image of a guest language used by an application, specify -language: for each guest language (e.g., -language:js). Polyglot embeddings can also be compiled ahead-of-time. The resulting image can, optionally, execute dynamic languages like JavaScript, Ruby, R or Python. Native Image supports JVM-based languages, e.g., Java, Scala, Clojure, Kotlin. This entire process is called building an image (or the image build time) to clearly distinguish it from the compilation of Java source code to bytecode. Then it ahead-of-time compiles that reachable code and data to a native executable for a specific operating system and architecture. It statically analyzes these data to determine which classes and methods are reachable during the application execution. The Native Image builder or native-image is a utility that processes all classes of an application and their dependencies, including those from the JDK. The resulting program has faster startup time and lower runtime memory overhead compared to a JVM. Substrate VM is the name for the runtime components (like the deoptimizer, garbage collector, thread scheduling etc.). It does not run on the Java VM, but includes necessary components like memory management, thread scheduling, and so on from a different runtime system, called “Substrate VM”. This executable includes the application classes, classes from its dependencies, runtime library classes, and statically linked native code from JDK. Native Image is a technology to ahead-of-time compile Java code to a standalone executable, called a native image.
