This repository contains scripts to build the cross-compiler for the Rust-based library OS HermitCore.
The build process works currently only on x86-based Linux systems. The following software packets are required to build HermitCore's toolchain on a Linux system:
- Netwide Assembler (NASM)
- GNU Make, GNU Binutils, cmake
- Tools and libraries to build linux, binutils and gcc (e.g. flex, bison, MPFR library, GMP library, MPC library)
On Debian-based systems the packets can be installed by executing:
sudo apt-get install nasm texinfo libmpfr-dev libmpc-dev libgmp-dev flex bison
We require a fairly recent version of CMake (
3.7) which is not yet present in
most Linux distributions. We therefore provide a helper script that fetches the
required CMake binaries from the upstream project and stores them locally, so
you only need to download it once.

So before you build HermitCore's toolchain you have to source the
everytime you open a new terminal.
Building the HermitCore's toolchain
To build the toolchain just call the script as follow:
$ ./toolchain.sh x86_64-hermit /home/usr/hermit
The first argument of the script specifies the target architecture, where the second argument defines the path to the installation directory. Do create the toolchain, write access to the installation directory is required.
