Build instructions

Here in detailed is describe dhow to build a native binutils for ppc-amigaos.

The build is experimental build, using the clib4 c library and development envirnoment based upon a Dockerfile. Thus docker is a minimal requirement

Setup

All commands are assumed from a base directory, like ~/workspace:

1. We need to check out the needed projects from AmigaLabs, the libs-port for mpfr library and of course the binutils branch
   $ git clone https://github.com/AmigaLabs/libs-ports.git
$ git clone --branch nativeOS4-build-clib4 https://github.com/AmigaLabs/binutils-gdb.git
2. Next start up the docker env for compiling. Still being in the ~/workspace directory:
   $ docker run -it --rm --name binutils_clib4 -v "${PWD}:/opt/code" -w /opt/code walkero/amigagccondocker:os4-gcc11-exp /bin/bash
3. Wait until the prompt appears for the started dockerfile. Than install the missing texinfo package
   > apt-get update
> apt-get install texinfo
4. Now switch to the amidev user within the docker env.
   > su amidev
5. Next compile and install the mpfr lib for clib4
   > cd libs-port/mpfr
> make init
> make build LIBC=clib4
> cd mpfr-4.2.1
> make install
6. Now prepare the build env. for binutils
   > cd ../../../binutils-gdb
> mkdir native-build
> cd native-build
7. Configure binutils to include the gdb in build:
   > CFLAGS="-mcrt=clib4 -DHAVE_POSIX_SIGNALS" CXXFLAGS="-mcrt=clib4 -DHAVE_POSIX_SIGNALS" ../configure --disable-plugins --disable-sim --host=ppc-amigaos --target=ppc-amigaos --prefix=/opt/code/binutils-gdb/dist-clib4/
8. Lets build:
   > make
   Optional pass -j n improve compile times
