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:
- gcc with libs for C/C++/ObjC
- 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 rsync
sudo apt install make wget git gcc g++ lhasa libgmp-dev libmpfr-dev libmpc-dev flex bison gettext texinfo ncurses-dev autoconf rsync
If building with a normal user, the
PREFIX directory must be writable (default is
/opt/amiga). You can add the user to an appropriate group.
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By default macOS uses an outdated version of bash.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
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 rsync
Windows with msys2
Precompiled suite with installer: http://franke.ms/download/setup-amiga-gcc.exe
pacman -S git base-devel gcc flex gmp-devel mpc-devel mpfr-devel ncurses-devel rsync
Also note that you MUST cd into an absolute path e.g.
cd /c/msys64/home/test/amiga-gcc/ before running make, or builds may fail, because some files aren't found correctly (that's a msys2 bug).

Howto Clone and Download All You Need
git clone https://github.com/bebbo/amiga-gcc cd amiga-gcc make update
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
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
The build performs the installation automatically, there is no separate
make install step. Because of this, you must make sure that the target
PREFIX directory is writable for the user who is doing the build.
PREFIX directory points to a directory where the user already has appropriate permissions the below steps can be ommited and the directory will be created by the build process.
sudo mkdir /opt/amiga sudo chgrp users /opt/amiga sudo chmod 775 /opt/amiga sudo usermod -a -G users username
After adding the user to the group, you may have to logout and login again to apply the changes to your user.
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^^.
If you plan to develop for Kickstart 1.3 you should use
-mcrt=nix13 in your compiler commandline
m68k-amigaos-gcc test.cpp -mcrt=nix13
The include files for 1.3 - which are picked up by the compiler if
-mcrt=nix13 is used - can be found at
