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 apt install make git gcc g++ lhasa libgmp-dev libmpfr-dev libmpc-dev flex gettext

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.
