Building from source

Here's how you build junixsocket from the source.


  1. Make sure you have a 64-bit Intel machine running macOS or Linux.

    If you have a different platform or architecture, continue here.

  2. Install the Java JDK 9 or newer (preferably Java 11), Maven 3.6 or newer, and junixsocket.

    Even though junixsocket can run on Java 8, you need Java 9 or better to build it, so we can support the new Java module system on newer Java versions.

  3. Install a development environment so you can compile C code (preferably clang/llvm).

    On macOS, this means installing Xcode. For development purposes, you may want to use the Xcode project defined in junixsocket-native/junixsocket-native.xcodeproj. However, this is not required. Running Maven (see below) is the authoritative way of building the native code.

    Also see here for instructions how to cross-compile for all supported architectures.

    Be sure to install bash, gcc,clang, ld/binutils, C headers (glibc-devel/libc-dev, musl-dev, etc.), and, optionally, for TIPC on Linux, Linux headers (e.g, linux-headers).

    For example, on Alpine Linux, run the following command:

    sudo apk add git maven clang gcc binutils bash musl-dev libc-dev linux-headers

Building with Maven

Build and test junixsocket.

cd junixsocket
mvn clean install

That's it!

Build options

While the default build options are a good start, you may want to change the level of scrutiny performed at build time.

Here's how to make building stricter (more potential errors are found):

mvn clean install -Pstrict

Here's how to make building less strict (this turns off several code quality checkers but will dramatically shorten build times):

mvn clean install -Dignorant=true

If some tests fail, you may try

mvn clean install -DskipTests=true

If you're having problems with building the native library, you can skip directly to building the Java code via

mvn clean install -rf :junixsocket-common

You can also try to build the full release version of junixsocket (which will include all cross-compile destinations) – see the release instructions for details:

mvn clean install -Pstrict -Prelease


If you don't have clang, try compiling with gcc. You may need to specify the compiler/linker at the command line:

mvn clean install -Djunixsocket.native.default.linkerName=gcc
