Make a really fast clone of all of AROS SVN, and be able to git svn dcommit

Working with GIT + SVN

There are many 'Using GIT with SVN' tutorials out there, but here's my workflow skeleton:

  • git svn fetch
    • Updates to current SVN tip
  • git checkout -b todays_project git-svn
    • Make a local branch to muck with
    • ( code code code )
  • git gui
    • Make my local commits - no pushes at this point
  • git svn fetch
    • update again, just in case
  • git svn rebase
    • pile my changes on top of current tip
  • ( Compile test )
  • git svn dcommit (push my changes upstream)

Toolchains

The following procedure will set up a m68k-aros toolchain in /opt/aros-m68k:

$ AROS=/sources/to/AROS
$ mkdir AROS.toolchain-m68k
$ cd AROS.toolchain-m68k
$ $AROS/configure --target=amiga-m68k \
                  --with-aros-toolchain-install=/opt/aros-m68k
$ make -s crosstools

To use the precompiled toolchain:

$ mkdir AROS.amiga-m68k
$ cd AROS.amiga-m68k
$ $AROS/configure --target=amiga-m68k \
                  --with-aros-toolchain-install=/opt/aros-m68k \
                  --with-aros-toolchain=yes \
                  --disable-crosstools
$ make -s

Nov 2, 2010: Frankenrom KS 3.0

This is just the AROS Exec, with everything else from AmigaOS KickStart 3.0.

Doesn't boot, but does ask for a disk. The disk insertion animation is correct, too.

Nov 6, 2010: AROS (no KS) ROM

This is All AROS, no Kickstart.

AROS SVN revision r35177, GIT revision 8ce2052d684cb0951990627b0e42ca32b4ec00b1

Capable of running:

  • EXILE100.ADF, md5sum f8d27184e8be07d1c9581de33d0b8b1a.
    • This is a trackdisk loading, not DOS boot sector disk. DOS boot sectors are not yet fully supported.

Nov 12, 2010: AROS Shell

Yep, that's right. The AROS Shell prompt. Whee!

Capable of running:

  • AROS Shell
  • A number of trackloading games

Not yet:

  • DOS loading games (no in-ROM shell to run their startup scripts)

What's horrible:

  • Had to change the ABI to the Graphics/*LayerRom routines to use A4 instead of A5, due to GCC issues. That's in the EVIL.patch
  • Doesn't boot if we're not strobing the serial port.
  • It's a 1M ROM set.

ROMs + E-UAE configs + AROS System Floppy + EVIL.patch

Nov 25, 2010: AROS Wanderer

Compiled straight off the AROS mainline,

  • SVN Revision r35751
  • git revision 76575383d5ff841598476ee7acd27476b59df21f
  • Can use the WinUAE/E-UAE RTG graphics
    • You need to have the CPU be a 68020 (not 680ec20!) or better, and
    • Have 24-bit addressing disabled
  • Can boot up to Wanderer
    • Requires 8M (ugh!) of Fast RAM
    • Takes a LONG to time and lots of RAM unless you disable the copying of FONTS: to RAM:Fonts in the AROS/S/Startup-Sequence script
    • VERY slow - some process is consuming 100% of the poor Amiga's CPU time.

Jan 11, 2011: AROS on Amiga 1200 + ACA 1230

Compiled straight off the AROS mainline,

  • SVN Revision r36531
  • git revision aafc932549b0e94b33737bae58b288d3b4cd826d

Running on a PAL Amiga 1200 with an ACA 1230/56 (for MAPROMing the ext+rom images).

  • No HDD support, so floppy only for now
  • Still no 'Wanderer Lite', so no Workbench (can't fit Wanderer on a floppy)
  • As you can see, you *can* run Intuition applications if you start them from S:Startup-Sequence, or the shell

Feb 8, 2011: ELF2HUNK utility

Not much to see here, just a program compiled on AROS as ELF running on AOS via my ELF2HUNK utility.

  • elf2hunktest.c
#include <intuition/intuition.h>

#include <proto/exec.h>
#include <proto/dos.h>
#include <proto/intuition.h>

int main(int argc, char **argv)
{
   struct EasyStruct easy = {
       .es_StructSize = sizeof(struct EasyStruct),
       .es_Flags = 0,
       .es_Title = "Elf2Hunk works!",
       .es_TextFormat = "Really, it does.",
       .es_GadgetFormat = "Yes|No",
   };
   PutStr("Hello World\n");

   EasyRequestArgs(NULL, &easy, NULL, NULL);
   return 0;
}

Compilation, from AROS SVN 37012:

$ make build-tools
$ bin/linux-x86_64/tools/m68k-amiga-aros-gcc  -Werror -Os  elf2hunk-test.c -o elf2hunk-test
$ mkdir /path/to/WB3.1/AROS
$ bin/linux-x86_64/tools/elf2hunk elf2hunk-test /path/to/WB3.1/AROS/elf2hunk-test

Run UAE with a stock Kickstart 3.1 ROM, with '/path/to/WB3.1/' mounted somewhere, and run 'elf2hunk-test' in a shell from the 'AROS' subdirectory. You should get something similar to the following:

AROS-ELF2HUNK.png

This demonstrates:

  • Compiling with the AROS toolchain, and deploying on AmigaOS
  • Automatic loading of 'dos.library' and 'intuition.library' by the AROS C runtime.

Todo:

  • Find some way to copy ELF debug information (maybe just symbols?) to HUNK


Nov 28, 2011: OpenGL under AROS m68k

Finally got around to getting C++ to compile for m68k, which allows Mesa to be compiled

Correction: .. but it doesn't work (yet)

The 'tunnel' demo shown below does not use Mesa.
