##### It took me countless hours to put this fragile software together. The time I can spend to develop this project is limited. If you want binary builds, better support for Windows or any other [feature](https://github.com/cahirwpz/amigaos-cross-toolchain/wiki/TODO), please incentivize me by leaving a tip.

**Short description:** Cross toolchain build script for AmigaOS m68k and ppc targets. Supported host platforms are Linux, MacOSX and Windows (with [MSYS2](https://msys2.github.io/)).
|
|
|
|
### Overview
|
|
|
|
**amigaos-cross-toolchain** project provides an easy way to build AmigaOS 3.x (m68k) and ppc AmigaOS 4.x (ppc) target toolchain in a Unix-like environment.
|
|
|
|
Build process should produce following set of tools for **m68k-amigaos** target:
|
|
|
|
* gcc 2.95.3
|
|
* g++ 2.95.3
|
|
* libstdc++ 2.10
|
|
* binutils 2.14 (assembler, linker, etc.)
|
|
* libnix 2.2 (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)
|
|
* vbcc toolchain (most recent release) including vasm, vlink and C standard library
|
|
* IRA: portable M68000/010/020/030/040 reassembler for AmigaOS hunk-format
|
|
executables, libraries, devices and raw binary files
|
|
* vda68k: portable M68k disassembler for 68000-68060, 68851, 68881, 68882
|
|
* [amitools](https://github.com/cnvogelg/amitools/blob/master/README.md#contents) with [vamos](https://github.com/cnvogelg/amitools/blob/master/doc/vamos.md) AmigaOS emulator which is proven to run SAS/C
|
|
|
|
... and following set of tools for **ppc-amigaos** target:
|
|
|
|
* gcc 4.2.4
|
|
* g++ 4.2.4
|
|
* binutils 2.18 (assembler, linker, etc.)
|
|
* newlib
|
|
* clib 2.2
|
|
* AmigaOS headers & libraries & autodocs (for AmigaOS 4.1)
|
|
|
|
**Note:** *Patches are welcome!*
|
|
|
|
### Downloads
|
|
|
|
There are no binary 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:
|
|
|
|
* Windows 7 SP1 32-bit (MSYS2 2.6.0, gcc 5.3.0)
|
|
* Ubuntu 16.04 LTS 32-bit (gcc 5.4.0)
|
|
* Ubuntu 16.04 LTS 64-bit (gcc 5.4.0) *Requires gcc-multilib package, and i386 libraries!*
|
|
* MacOS X 10.9.5 (MacPorts - Apple's clang-600.0.57)
|
|
|
|

### Compiling
|
|
|
|
*Firstly… you should have basic understanding of Unix console environment, really* ;-)
|
|
|
|
#### Prerequisites
|
|
|
|
You have to have following packages installed in your system:
|
|
|
|
* GNU gcc 5.x **32-bit version!** or Clang
|
|
* Python 2.7.x
|
|
* libncurses-dev
|
|
* python-dev 2.7
|
|
* GNU make 4.x
|
|
* perl 5.22
|
|
* git
|
|
* GNU patch
|
|
* GNU gperf
|
|
* GNU bison
|
|
|
|
*For MacOSX users*: you'll likely need to have [MacPorts](http://www.macports.org) or [Homebrew](http://brew.sh) 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 *amigaos-cross-toolchain* project to your local drive:
|
|
|
|
```
|
|
# git clone git://github.com/cahirwpz/amigaos-cross-toolchain.git
|
|
# cd amigaos-cross-toolchain
|
|
```
|
|
|
|
2. Run `toolchain-m68k` or `toolchain-ppc` script (with `--prefix` option to specify where to install the toolchain). Note, that the destination directory must be writable by the user.
|
|
|
|
```
|
|
# ./toolchain-m68k --prefix=/opt/m68k-amigaos build
|
|
```
|
|
|
|
3. Wait for the result :-)
|
|
|
|
4. *(optional)* Install additional SDKs (e.g. AHI, CyberGraphX, Magic User Interface, etc.):
|
|
|
|
```
|
|
# ./toolchain-m68k --prefix=/opt/m68k-amigaos install-sdk ahi cgx mui
|
|
```
|
|
|
|
#### What if something goes wrong?
|
|
|
|
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!
|
|
It's **vitally important** to send me a full log from build process. You can capture it by redirecting output to a file with following command:
|
|
|
|
```
|
|
# ./toolchain-m68k build 2>&1 | tee build.log
|
|
```
|
|
|
|
... but remember to cleanup your build environment beforehand with:
|
|
|
|
```
|
|
# rm -rf .build-m68k
|
|
```
