Gemstone

Gemstone is a programming language compiler written in C with lex and yacc.

Build

The build pipeline is configured with CMake in the file CMakeLists.txt. In order to avoid dependency and configuration issues the recommended way to build is by using the provided docker containers. All tools required for building (cmake, make, gcc, lex, yacc) are installed inside the SDK container (see Dockerfile sdk/Dockerfile). For creating the build pipeline build the Dockerfile in the root folder of this repository. This takes the current SDK and copies the source files into the home of the build user. Then the make targets are generated. Running make release will build gemstone from source in release mode. The generated binaries can be found either in bin/release/gsc or bin/debug/gsc depending on the chosen target. The following graph visualizes the build pipeline:

                  │ configure build environment
                  │  cmake, make, gcc, yacc, lex

Docker images

Currently, the SDK is based on Almalinux 9.3, an open source distro binary compatible to RHEL 9.3.

The following images can be found in the offical repository at Docker Hub:
