Saphyr Compiler

Build Status Bugs Coverage Status

A C++ Like compiler using LLVM as a backend.


Unless otherwise stated the source code is licensed under the GPLv3 -- see LICENSE.

Build Dependencies

  • FlexC++
  • BisonC++
  • Boost
    • Program_Options
    • Filesystem
    • System
  • LLVM 3.8+
  • Make
  • C++14 compiler (either GCC or Clang)
  • Python 3 (for running tests)
  • Saphyr-libs (for tests)
  • Icmake (required if building FlexC++/BisonC++ from source)
  • Bobcat (required if building FlexC++/BisonC++ from source)


Debian 9 (Stretch) and Ubuntu 16.04 (Xenial) or newer have all the required packages in their repositories.

sudo apt-get install flexc++ bisonc++ make llvm-dev libboost-program-options-dev libboost-filesystem-dev libboost-system-dev clang python3


A local portage overlay containing bobcat/flexc++/bisonc++ is provided in scripts/portage. After adding the overlay run emerge saphyr to install all required dependencies.


FlexC++/BisonC++ can be found in the AUR along with their dependencies icmake and libbobcat. The other dependencies can be installed using:

pacman -S make llvm boost clang

Other Linux

Install: make, clang, llvm, boost and python3 for your Linux distribution. If your distribution doesn't have flexc++/bisonc++ then you can use the jdm64/saphyr docker image to build the frontend by running:

sudo make frontend-docker

NOTE: On Fedora you must disable SELinux (sudo setenforce 0) or you will get a permission error.

Build Instructions

Run make in the src directory and it will build the compiler binary saphyr.

You can’t perform that action at this time.
