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)

sudo yum install wget 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

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

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 wget make lhasa gmp mpfr libmpc flex gettext texinfo gcc make autoconf

By default macOS uses an outdated version of bash.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 brew version of gcc make and autoconf, e.g.:

CC=gcc-9 CXX=g++-9 gmake all SHELL=/usr/local/bin/bash

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

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

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

git clone https://github.com/bebbo/amiga-gcc
cd amiga-gcc
make update

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

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

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^^.
