AmigaOS/m68k targeted cross compilers and assembler

Author: Krystian Bacławski

Short description: m68k-amigaos gcc / binutils / vbcc / vasm toolchain build script.

Overview

m68k-amigaos-toolchain project provides an easy way to build m68k AmigaOS 3.x target toolchain in a Unix-like environment. Build process should produce following set of tools:

• gcc 2.95.3
• g++ 2.95.3
• libstdc++ 2.10
• binutils 2.9.1 (assembler, linker, etc.)
• libnix 2.1 (standard ANSI/C library replacement for AmigaOS)
• libm 5.4 (provides math library implementation for non-FPU Amigas)
• AmigaOS headers & libraries & autodocs (for AmigaOS 3.9)
• ixemul.library 48.2
• vbcc 0.9b + vclib
• vasm 1.6b
• vlink 0.14c

Note: Patches are welcome!

Downloads

There are no downloads provided for the time being. I do as much as possible to make the toolchain portable among Unix-like environments. Following platforms were tested and the toolchain is known to work for them:

• Cygwin 1.7.18 (gcc 4.5.3)
• Ubuntu 14.04 LTS 32-bit (gcc 4.8.2)
• Ubuntu 14.04 LTS 64-bit (gcc 4.8.2) Requires gcc-multilib package, and i386 libraries!
• MacOS X 10.9.3 (MacPorts - Apple's clang-503.0.40)

Documentation

Documentation from Free Software Fundation:

• gcc 2.95.3
• gcc 3.4.6
• binutils

Texinfo documents from GeekGadgets converted into HTML:

• libnix - a static library for GCC on the amiga
• AmigaOS-only features of GCC

AmigaOS specific documents:

• Amiga Developer Docs

Compiling

Firstly… you should have basic understanding of Unix console environment, really ;-)

Prerequisites

You have to have following packages installed in your system:

• GNU autoconf
• GNU flex 2.5.x
• GNU gcc 4.x 32-bit version!
• GNU make 3.x
• lha
• perl 5.10
• libncurses5-dev 32-bit version!

For MacOSX users: you'll likely need to have MacPorts or Homebrew installed in order to build the toolchain.

How to build?

Warning: Building with sudo is not recommended. I'm not responsible for any damage to your system.

Follow steps listed below:

1. Fetch m68k-amigaos-toolchain project to your local drive:

git clone git://github.com/cahirwpz/m68k-amigaos-toolchain.git

cd m68k-amigaos-toolchain

2. Download sources (use `fetch.sh` script in `archives` directory):   

    ```
# cd archives   
# ./fetch.sh

3. Run bootstrap.sh script (with --prefix option to specify where to install the toolchain). Note, that the destination directory must be writable by the user.

cd ..

./bootstrap.sh --prefix=/opt/m68k-amigaos build

4. Wait for the result :-)

5. *(optional)* Install additional SDKs (e.g. AHI, CyberGraphX, Magic User Interface, etc.):

    ```
# export PATH=/opt/m68k-amigaos/bin:$PATH
# ./install-sdk.sh --prefix=/opt/m68k-amigaos ahi cgx mui

Note: If the build process fails, please write me an e-mail. I'll try to help out. Don't forget to put into e-mail as much data about your environment as possible!
