Setting up C++ compiler toolchain

TechnoZealot · Post by **TechnoZealot** » Fri Dec 20, 2013 12:35 pm

HI! I've been trying fruitlessly to compile GCC with C++ and Objective-C support using Chilly WIlly's excellent tutorial using MinGW and MSYS, but cannot seem to get some parts to compile, specifically binutils and mpfr.

Does anyone have a compiled binary for m68k-elf-c++.exe?

Thanks!

Hi!

Do you mean from this thread? (viewtopic.php?t=1045) Or another?

Yes, from that thread. Sorry, I should have put a link in the first post!

I tried building for Windows a while ago. Have you seen my post in the thread?

viewtopic.php?p=18727#18727

There was a step that wasn't clear in the original instructions.

I remember having trouble figuring out where which folder went where.

I think the only difference for me was that I used the most recent version of MinGW/MSYS and I am [regrettably] running Win8.

I don't think my MSYS setup even has an /opt directory to copy though .ld files to.

You should try the exact versions in Chilly's instructions, just to be safe.

Is there a place where I can get a precompiled binary of this? I am having a lot more trouble than I think I should be.

Sadly, I don't know.

No problem. I'm hoping I get this to work. If anyone can find a copy of m68k-elf-c++.exe, I would be much obliged.

If you're having trouble building the toolchain, there might be other problems than just a missing executable. But you'll probably find them once you start building

I had build errors originally. I am just looking for a prebuilt binary if that is around somewhere. I couldn't find any online.

That is, unless I can fix my build process.

I am going to give the tutorial from SEGA-16 another try...

Wish me luck!

Keep getting this error:

Have you tried binutils 2.22 ? That's the version suggested in Chilly's instructions.

I can't find anything in the changelog from 2.21 to 2.22 about the problem, but it's worth a shot.

Ah! I'll try that!

I don't think that's the issue though, because I did a couple of other setups and got different errors at different stages, some very lacking in description, even when only trying to build the targets for pass2 of the gcc compiler.
