# amiga-gcc [](https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=YRRBRLCKDU3H6)
|
|
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 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`
|
|
### Ubuntu, Debian
|
|
`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.
|
|
|
|
### 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 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By default macOS uses an outdated version of bash.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`
|
|
|
|
### 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
|
|
```
|
|
pacman -S git base-devel gcc flex gmp-devel mpc-devel mpfr-devel ncurses-devel rsync
|
|
```
|
|
|
|
### Ubuntu running on the Windows 10 Linux subsystem

## 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
|
|
```
|
|
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.
|
|
If the `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.
|
|
|
|
## 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^^.
|
|
|
|
## Kickstart 1.3
|
|
|
|
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 `<PREFIX>/m68k-amigaos/ndk13-include` i.E. `/opt/amiga/m68k-amigaos/ndk13-include`
