To get the code to build successfully under MinGW the following changes were made. The configure command for some of the projects had to be changed from absolute paths to relative paths to avoid build errors relating to path name issues under windows. GMP, MPC and MPFR are built as part of GCC. fd2sfd has a patch for it to build under MinGW. sfdc is patched to remove carrage returns from the sfd files. This was causing errors in the generated include files.
amiga-gcc
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 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

Howto Clone and Download All You Need
git clone https://github.com/bebbo/amiga-gcc
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^^.
