NitrOS-9 Languages

This repository contains programming languages, compilers, and related tools for NitrOS-9.

Contents

• basic09 — Microware BASIC09 and RunB sources, utilities, and samples
• bf — Brainf*ck interpreter and sample programs
• ccompiler — Microware C compiler, libraries, headers, and sources, and the source of Carl Kreider's compatible C library, KLibc (ccompiler/klibc)
• c3 — C-Cubed, a portable C compiler derived from the Microware one; it runs on the build host as a cross compiler and on NitrOS-9 itself
• pascal — archival Pascal materials

The Microware source in basic09/microware is the authoritative source for the BASIC09 and RunB modules. Generated or separately disassembled versions are not maintained as competing sources.

Building

A neighboring NitrOS-9 checkout is used by default:

make

Set NITROS9DIR when the NitrOS-9 checkout is elsewhere:

make NITROS9DIR=/path/to/nitros9

The default target builds BASIC09, Brainf*ck, the C compiler, and c3, including their disk images. The BASIC09 disk is based on the CoCo 3 floppy recipe in the NitrOS-9 checkout. Use make clean to remove generated modules and disk images.

c3 also needs a host C compiler. It is built first as host executables, then used to cross-build itself to OS-9 modules. Its disk image also needs the Microware assembler and linker from a CoCo C checkout. Without one, the c3 tools are still built but the disk is skipped:

make COCOC=/path/to/CoCoC

make -C c3 ontarget COCOC=/path/to/CoCoC checks that the disk self-hosts: it boots NitrOS-9 under the usim09pt emulator, builds c3's C libraries on the target, and compiles and runs a program there. c3/build/os9/ontarget.sh lists what it needs.

The Pascal material is retained for reference and is not part of the aggregate build.

Source and licensing

These packages were migrated from the NitrOS-9 3rdparty/packages tree. They retain their original source notices, documentation, and licensing terms. No repository-wide license is asserted over packages that do not already include one.
