The GNU C-Compiler with Binutils and other useful tools for cross development

This is a Makefile based approach to build the same files as in the old amigaos-toolchain to reduce the build time.

Right now these tools are build:

  • binutils
  • gcc with libs for C/C++/ObjC
  • fd2sfd
  • fd2pragma
  • ira
  • sfdc
  • vbcc
  • vlink
  • libnix
  • ixemul (not really, but the headers are used)

Short Guide

Prerequisites

Centos

sudo yum install gcc gcc-c++ python git perl-Pod-Simple gperf patch autoconf automake make makedepend bison flex ncurses-devel gmp-devel mpfr-devel libmpc-devel gettext-devel texinfo

Ubuntu

sudo apt install make git gcc g++ lhasa libgmp-dev libmpfr-dev libmpc-dev flex bison gettext texinfo ncurses-dev

macOS

Install Homebrew (https://brew.sh/) or any other package manager first. The compiler will be installed together with XCode. Once XCode and Homebrew are up install the required packages:

brew install bash make lhasa gmp mpfr mpc flex gettext texinfo

By default macOS uses an outdated version of bash. Therefore, on macOS host always pass the the SHELL=/usr/local/bin/bash parameter (or any other valid path pointing to bash), e.g.:

make all SHELL=/usr/local/bin/bash

On macOS it may be also necessary to point to the correct compiler version (there is a gcc wrapper for clang, which can produce compile errors!), e.g.:

CC=clang CXX=clang++ make all SHELL=/usr/local/bin/bash

ALSO NOTE If you want m68k-amigaos-gdb then you have to build it with gcc

Windows with Cygwin

Install cygwin via setup.exe and add wget. Then open cygwin shell and run:

wget https://raw.githubusercontent.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
apt-cyg install gcc-core gcc-g++ python git perl-Pod-Simple gperf patch automake make makedepend bison flex libncurses-devel python-devel gettext-devel libgmp-devel libmpc-devel libmpfr-devel

Windows with msys2

pacman -S git base-devel gcc flex gmp-devel mpc-devel mpfr-devel ncurses-devel

Ubuntu running on the Windows 10 Linux subsystem

cd amiga-gcc
make update

Overview

make help

yields:

make help 		        display this help
make all 		          build and install all
make <target>		      builds a target: binutils, gcc, fd2sfd, fd2pragma, ira, sfdc, vbcc, vlink, libnix, ixemul, libgcc
make clean		        remove the build folder
make clean-<target>	  remove the target's build folder
make clean-prefix	    remove all content from the prefix folder
make update		        perform git pull for all targets
make update-<target>	perform git pull for the given target

display which targets can be build, you'll mostly use *make all *make clean *make clean-prefx

Prefix

The default prefix is /opt/amiga. You may specify a different prefix by adding PREFIX=yourprefix to make command. E.g.

make all PREFIX=/here/or/there

Building

Simply run make all. Also add -j to speedup the build.

make clean
make clean-prefix
date; make all -j3 >&b.log; date

takes roughly 10 minutes on my laptop running ubuntu. takes forever running cygwin on windows^^.
