Welcome to Amiga-Gcc

This project provides you a configuration to download, configur and build a cross-compiler toolchain for the classic AmigaOS with 68k based cpus.

Supported Plattforms

It's known to build properly on Centos 7.5 64 bit, Cygwin 32/64bit, Linux Mint 17.10, Ubuntu 17.*/18.* and OSX. Guess more plattforms will do.

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 gettext texinfo

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

How to build/update

git pull
make update -j
make all -j4

To clean run

make clean clean-prefix -j

What libraries are provided?

At time of writing you may select one of 3 libraries to create your programs:

Library	newlib	libnix	clib2
switch		-noixemul or -mcrt=nix20	-mcrt=clib2
supports Kickstart 1.3	no	yes -mcrt=nix13	no
code size	larger	smaller	dunno
status	quite new	stable	stable
-lsocket	no	yes	yes

Quality of the libs

There is a project with tests for libc: git://git.musl-libc.org/libc-testsuite Here are some results of its tests.

A number is the count of errors, - is not built, -1 test does not run properly
