-Os and -O1 gives me compiler errors.

Maybe these errors are related to why I can no longer execute milkytracker when compiled with -O3?

Uhm yes, found that bug and fixed it. Milky compiles here again.

Awesome! Thanks =)

It's been a while since I did some testing, so I'd like to get in on this compiling MilkyTracker thing.

I've cloned this git repo: https://github.com/milkytracker/MilkyTracker

But I don't see any makefile, only a cmake directory, so I'm confused. How do I compile this? (cygwin-32/win7-64)

This is my fixed version: https://github.com/mbeijer/milkytracker-amiga68k

it requires premake4 to create the makefile.

I'm not done with optimizations, so currently it only runs at a decent speed in UAE-JIT 040. Just fyi.

Browsing files inside milkytracker doesn't work either, so you have to load files from commandline. So it's far from usable at this point.

My plan is to "remove" SDL and add in CGX RTG support instead and go straight for AHI myself, in hopes for getting some improvements by removing overhead. I'd like it to at least run on a Vampire accelerated Amiga in a foreseeable future.

premake4 comes with your distribution, right? Or do I have to download/install that separately? Because it says it can't find premake4 when building the makefile:

Code:

$ ./build_gmake
./build_gmake: regel 2: premake4: opdracht niet gevonden

https://premake.github.io/download.html#v4

I have included premake4 and premake4.exe, first being for linux, second for windows. You just need to modify the build_gmake file to run the included executable.

But this is off topic discussion, if you need further help, send me a PM.

Guess I was cheating... it was 28mins.

And I added a new switch: --mytools

Code:

./toolchain-m68k build --mytools --threads 8 --prefix /opt/amiga >& b.log

using --mytools most of the tools are not built, instead it's required to have these installed and working.

=> speeds up build process :-)

Oh, so if I only need to update gcc and no other surrounding tools, --mytools will suffice? But the linker and stuff still gets built, right?

Darn, that still beats my 35 minutes..

Marlon_ · 20 June 2017, 21:36

Hmm, still get "Program aborted" with -O1, -O2 and -O3, then UAE locks up.
Do you get it to run after it's compiled?

I never tried running this... needed the SDL lib to link.

It dies at SDL_SYS_CreateThread, because DOSBase is 0. And DOSBase is not an alias for __DOSBase which is initialized...

Well, it was working before, and I haven't made any changes since last time.

EDIT:
How do you debug by the way? I need to sort that out so I can develop this properly.

bebbo · 20 June 2017, 22:57

hm - I dislike the linker - library order matters a lot

-> will check the link specs and compare with previous versions...
... and then math stuff will break again
... /sigh

The struggle! Your work is highly appreciated though! Too bad there's only one of you. Would be nice if someone knowledgable about compilers could help you out.

I unfortunately know nothing about that stuff and am afraid I would just break it further. :P

Do you have a patreon or something to show you support?

bebbo · 21 June 2017, 09:32

OK - I tries different older revisions - and none worked out. Always the same crash.

SDL-1.2.15.lha is crashing.

Then I tried a different libSDL.a and finally an empty window shows up plus some complaints in the console window about a missing audio device...

Which libSDL.a is the correct one to use?

I have me ^^ and I found a bug in the flow analysis that caused some parts of code not been evaulated at all: tail calls which are converted into a jump.

PUSH

should I get more than this complaint? "SDL: failed to open audio device! ..."? with my UAE?

And consider using

Code:

-fno-rtti -fno-exceptions

to reduce the code size a tiny bit.

The one referred to in the github repo works: http://aminet.net/package/dev/misc/SDL-Amiga

What I get when I start the application is an actual SDL window, the "intro"-screen, then when it's supposed to show the actual program contents I get "Program aborted" and the SDL window just stays.

Do you have AHI installed? It is needed. AHI set to Paula Stereo++ should work.

OK - AHI audio driver is found now.
Now I have an empty window - no abort - no complaints.

Do I need further libraries?

Marlon_ · 21 June 2017, 14:34

only the ones stated in my github repo readme. I get the MilkyTracker logo in the window, that then fades out to black and should show the actual tracker interface. But when it's supposed to show the tracker interface it aborts.

I haven't tried your latest changes yet though.

I recommend using the latest fix.

And btw: I am using my old old old hard disk image which I was using 20+ years ago on my A2000/040 then A3000/030 - don't ask but there are loads of libs in ancient versions...

... maybe I should setup a new vanilla wb...

PS: new there is now a milkytracker_config file
