GCC 6.2 toolchain for AmigaOS 3

[jotd]

Yeah. I'll adapt my engine to use non-SDL graphics & sounds. I'll keep the event stuff, as it is probably not very CPU hungry.

Hello guys, i have an invalid constraint in asm error with this code. If someone has information it will be appreciated, thanks!

INLINE u32 castToU32(float x)
{
u32 value;
__asm ("fmove%.l %1,%0" : "=d" (value) : "f" (x));
return value;
}

I forgot to mention i use -68060 flag and this code worked in old 3.4 gcc version.

[jamie]

-mhard-float did the job!

[jotd]

good for you! -mhard-float should always be used because the alternative is soft float which is slow as hell, specially if you have a 68060 it makes no sense (unless you want exactly the same results like on a 68000)

Hi I've got a fresh install of lubuntu 64bit installed as a virtual machine and thought I'd give this a go, can someone help me install it?


Is this info still current and does it apply to my setup?


https://github.com/bebbo/amiga-gcc

Prerequisites


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


How to Clone and Download All You Need

git clone https://github.com/bebbo/amiga-gcc
cd amiga-gcc
make update



I'd also like to get CDT running on lubuntu if possible using this build of gcc.


I'm still learning Linux BTW (more of a Windows user)

Thanx

Just check out the Amiga-gcc repository,

Then
make all all-sdk -j8 PREFIX=<path to where you want the toolchain>

E voila! It‘ll download some extra sdk‘s and build the whole toolchain (with newlib, clib2 and noixemul all installed in parallel) all in one go.

The binaries to compiler, linker, assembler will be found under <yourprefixpath>/bin and you should add them to your path.
The toolchain comes with a bunch of essential libs (like ahi, cgx, sdl and the AmigaOS 3.0 and 1.3 sdks), so you can get off the ground very quickly.

[NovaCoder]

Thanks for the that, I'll give it a try

Turns out Tapatalk swallowed parts of my message. PREFIX= should point to the directory where you want the built toolchain to be installed. The toolchain executables are installed underneath in „bin“ with the system includes and ndk etc in parallel

OK thanks, I'll give it a try tonight.

What's a good directory to use for the PREFIX?
Should it be something like /usr/bin/gcc?

[pipper]

It’s really up to you. I personally didn‘t like the /opt/amiga directory, and just put it into my home directory somewhere under $HOME/

Hi,

I gave it a try last night and it didn't quite work out (no doubt due to my lack of Linux skills ).

Lubuntu doesn't come with make or gcc so I install both of them first and then pulled down https://github.com/bebbo/amiga-gcc into /home/novacoderDevelopment/amiga-gcc.

I then tried make all all-sdk -j4 PREFIX=/home/novacoder/Development/amiga

And it spewed out the following stack trace (attached), any ideas?

[pipper]

Seems this is the issue:
make: *** No rule to make target 'projects/newlib-cygwin/configure', needed by 'build/newlib/newlib/Makefile'. Stop.

make: *** Waiting for unfinished jobs....

Not sure why there is Cygwin business in a native Linux environment ?!

Did you do this?

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

Yep, was that my bad?

I'm not a Linux guy BTW, just starting out with Ubuntu

Yep I noticed that too, thought it was a bit weird.

Nah, you're supposed to do that. Just making sure.

Did you run "make update" before "make all"?

Nope, I'll try that now.

Thanks

Update: Seems happier now, still building...



OK that worked, now trying to use eclipse CDT, anyone have any tips?

Thanks
