Port of libsss to Java using GCC-Bridge

This project is a port of dsprenkels/sss to Java using Renjin's GCC-Bridge. It compiles the original C sources to JVM bytecode using GCC-Bridge and provides convenient wrapper methods to access the generated methods.

Requirements

The GCC-Bridge Maven plugin requires GCC 4.7 to be installed to compile C sources. On Ubuntu GCC 4.7 was available on version 16.04 but is not available on more recent versions and the GCC-Bridge currently relies on that specific version of GCC.

To make the build work on a modern system, vagrant is utilized to set up an old Ubuntu virtual machine and builds the project there. The build artifacts are then platform independent and can be used on any system.

Compiling

To compile the C sources, first go to the bridge directory.

There you need to set up the build virtual machine using vagrant:

vagrant up

After that completed you can ssh into the machine and build the project:

vagrant ssh
cd sss-gcc-bridge
mvn install

Vagrant uses the project directory on your real local machine as a shared folder so that the build results are available in your target directory locally.

When you're done, shut down the virtual machine:

vagrant halt

Then, from the toplevel directory of the whole project, copy the generated JAR file to the main project:

cp bridge/target/sss-gcc-bridge-1.0.0.jar sss-gcc-bridge/bridge/

Switch to the sss-gcc-bridge directory and build using Gradle:

./gradlew build
