i just looked at your gcc diffs
https://github.com/gcc-mirror/gcc/co...b74985ab353fbb
and it shouldnt to be to difficult to merge in even though aros is 6.3.0 and yours 6.3.1. already. one could create an alternative diff to build aros compiler for the time being and check out if and how it works. i know kalamatee is against too much changes in order to have an option to push it upstream an have it eventually accepted.

the main issues for now are probably though the scripts adoptations. this will be beyond my abilities. but i might try to create diff in if need be without too much typos i hope.

Sorry to barge into this amazing thread with some general usage noob questions. I'm looking for a modern way to (learn how to) program the Amiga, and this might be it. I'm currently running SAC/C 6.58 on my A1200 itself, but maybe I can do better than that. So here's a couple of questions:

1. Will I be able to use Visual Studio to build Amiga executables? I mean, including all those nice features like intellisense, 'go to definition' and 'find all references'? I think I read that you can use Eclipse, but I'm not sure wether this is under Windows or under Cygwin.
2. Will I be able to build this project: http://eab.abime.net/showthread.php?t=78295
3. Why are there (almost) no binary distributions for this toolchain?

Anyway, this has been a very interesting read, even though I probably only understood about 20% of what has been said..

Thank you and keep it up, bebbo!

1. Not sure, but I use code::blocks together with this toolchain just fine.
2. No clue, go ahead and try.
3. It's heavily under development with tweaks and fixes almost every week. Keeping up with the development and doing binary distributions for each OS would be tedious. Building the toolchain yourself is not that hard since the scripts does it all for you basically.

Thanks for the input, Marlon_!
1. Under windows? I mean, can windows even read the cygwin files (and/or vice versa)?
2. I might just do that!

3. Ok, I see.

It works for me in MacOS and Linux. Haven't tried on Windows myself. It was ages ago I tried cygwin, so I'm not sure how that works. Perhaps someone else can shed some light on that.

No doubt about that!

Using win7-64bit, btw..

@1. Visual Studio won't work out of the box. Eclipse is doing fine and provides all that nice stuff you want - plus it's working with Windows, Linux or OSX. Running Eclipse with Windows requires the amigaos-toolchain compiled with Cygwin (I 'm using the 32 bit Cygwin, but 64 bit is also ok). Thanks to my changes the include and library paths are autodetected with Windows/Eclipse/Cygwin, so its quite smooth.

@2. The project does not compile out of the box due to some unknown keywords like 'far'. But that should be fixable - maybe the 'chip' attribute requires some effort - or start "nofastmem" on your Amiga ;-)

@3. The reason for not many prebuild binaries (there are some...) and no Windows Installer to install it somewhere is the pita also known as gcc. gcc requires a fixed path to be installed in, which is defined during compile time.

Thanks for your answer, bebbo, much appreciated!

1. Well, using Visual Studio was my best case scenario, but I'd be very happy to get this going with Eclipse, too. I've used Eclipse in the past, when doing some python dev, although it's been about 10 years. So I'll be going with Cygwin-64, I guess, because why not, right?
2. Well this definitely will be the first thing I'll try to get compiled if I get this toolchain working.

3. Oh, it's even worse than I thought, then.. No worries, though, I'll surely be able to compile this myself..

guy lateur · 08 June 2017, 21:31

So I installed Cygwin-64 and tried to build this. It seems to give an error when I do the 2nd step of "how to build" in the readme, ie "./toolchain-m68k --prefix=/opt/m68k-amigaos build". I've tried doing it again, with the same result. Here's what it says at the end:

Code:

Guy Lateur@guy-thuisbak ~/amigaos-cross-toolchain
$

Is that bad? How do I continue? I don't see any other errors in the log. Is it because of the space in the subdir 'Guy Lateur'?

bebbo · 08 June 2017, 21:47

yes, use a path without spaces

That path comes with my windows user name. So do I need to make (and log in as) a different user (I'd rather not), or can I redirect this somehow?

You may pick any path you like if that path is writeable to you.

Why not create a folder somewhere? Or move the amigaos-toolchain folder to c:\ ?

Made a folder /home/guy, trying again..

guy lateur · 08 June 2017, 23:08

Now I get this:

Did you install all required packages?

guy lateur · 08 June 2017, 23:33

Well I did this, if that's what you mean:

Code:

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

Didn't seem to give any errors, AFAIK..

bebbo · 08 June 2017, 23:54

Good. So we know now: Cygwin 64 bit is not ok.

Use Cygwin 32 bit then rinse and repeat.

EDIT:

or edit the file

Code:

/cygdrive/..../amigaos-cross-toolchain/.build-m68k/sources/gawk-3.1.8/posix/gawkmisc.c

and insert at the top

Code:

#include <io.h>

EDIT2:

use the 32bit version - there will be further problem's with cygwin 64 bit

guy lateur · 09 June 2017, 00:25

Hmm, can't seem to remove cyg64 nor install cyg32 (latter one has troubles with my avg virus scanner). I should probably try again later, like this weekend..

Thanks for all the help, peeps!

I'll let y'all know how this goes..

bebbo · 09 June 2017, 10:01

Cygwin/64bit is working now. Just pull the latest changes.

Sounds great, I'll test it out as soon as I have some time!
