How to build AmigaOS4 cross-compiler (Binutils 2.23.2 & GCC 8.3.0) on CYGWIN

I didn't mean changes in the adtools repository, that's frozen in time, but the official GCC repository. If I was in the wrong directory, then shouldn't

have failed too? I guess I have no other choice but to start from scratch.

edit: I found the problem. The tags in official GCC repo got renamed. There used to be "gcc-8_3_0-release":
https://webcache.googleusercontent.com ... &cd=1&hl=en&ct=clnk&gl=hu
But now it's "releases/gcc-8.3.0":
https://gnu.googlesource.com/gcc/+refs

This is why gild no longer works... Now I have to figure out where it stores the name of this tag.

edit #2:
So here's the solution, this could be added to the original post. Open "adtools/gcc/series" in a text editor, and replace

WARNING: When cross-compiling PKG_CONFIG_LIBDIR must be set to the location of the .pc files for the target

Also:
error: unrecognized option: --build=x86_64

How to fix those?

@Raziel
When configure want PKG things, then:

export PATH=/usr/local/amiga/ppc-amigaos/SDK/local/newlib/bin/:$PATH

./configure --host=ppc-amigaos --target=ppc-amigaos PKG_CONFIG=/bin/pkg-config PKG_CONFIG_LIBDIR=/usr/local/amiga/ppc-amigaos/SDK/local/newlib/lib/pkgconfig


(so we use cross-compiler's pkg-config but our .pc files and skip --build=x86_64 option)

@kas1e

Can this be automated?
Is there a file i can edit to make the PKG_CONFIG persistent?

Unrecognized option
PKG_CONFIG=
PKG_CONFIG_LIBDIR=

@Raziel
Everything can be automated, i for myself just didn't bother.

Try to run ./configure --help | grep PKG to see what options it have.

But it strange, you post "WARNING: When cross-compiling PKG_CONFIG_LIBDIR must be set to the location of the .pc files for the target", i usually have that when configure accept PKG_CONFIG_LIBDIR.

But then try to set it as environment then, like:

export PKG_CONFIG_LIBDIR=/usr/local/amiga/ppc-amigaos/SDK/local/newlib/lib/pkgconfig

I am taking baby steps to compile simple things from Linux..

When I try to cross compile something, I get following error:

e.g.

CMake Error: The source directory "/amiga/Projects/flac-1.3.3/flac-1.3.3" does not appear to contain CMakeLists.txt.

What can be the solution ?

@SinanSam460

Kas1e covered this in the first post.

@derfs

Thanks but I got this error after following the final step.

@SinanSam460

you need to be in the “build” directory when you run cmake.

@kas1e

How do we update gcc 10 and latest updates on CygWin64 ?

@SinanSam460

All the same as with gcc8, but the only difference that you clone the gcc10 branch from sodero's repo, and apply gcc 10 patches. I.e. the whole block will be:

And then doing all the same as usual (change SDK link, etc, etc).

@kas1e

Thanks

I am getting this error when compiling new gcc

The way I compile it on docker using Ubuntu 20.04 can be found at https://github.com/walkero-gr/AmigaGCConDocker/blob/main/Dockerfile

There you can see the bash commands I use. Have in mind that this supports gcc 8, 9 and 10, which is set on an ENV variable called GCC. Check this out and you might find a missed step on your setup.

@kas1e

Do i need to do something special with gcc11?

I tried to install the whole package, but when i picked gcc11 no ppc-amigaos-gcc binary was created?

Is it mandatory to use gcc8 while cross-compiling?

@Raziel
At https://github.com/walkero-gr/AmigaGCC ... blob/main/base/Dockerfile you can see how I did it on docker with Ubuntu 20.10. When I did it a few months ago it worked just fine and there is a docker image with GCC 11.1.0 working fine, as much as I know.

Maybe that helps you. If you need more info, please do not hesitate to ask me.

@walkero

Erm, thank you...but i don't know nothing about Linux, i don't even know what a docker is, so...sorry

Going to try the gcc8 approach in cygwin now

@Raziel

Nope, something is wrong with the build process, i don't get ppc-amigaos-gcc build neither with gcc8 nor gcc11.

All the other ppc-amigaos-xxx binaries are there, but no gcc, c+++ (and whatever the compilers are named)

@Raziel

I built ppc-amigaos-gcc-8.4.0 just a few days ago. Here are my personal notes from installing adtools which are just rewritten from the ones in this thread.

This assumes Cygwin has been set up with all the appropriate packages.

@derfs

Your steps are the exact same as in post 1.

But i followed them anyway, to no avail.

I don't get it.
Shouldn't the compiler binary be build and placed into
usr/local/amiga/bin ???

I have every other ppc-amigaos-xxx in there, but i always miss the compiler binaries...why???

Could you maybe upload your ppc-amigaos-g++ etc. binaries somewhere )or send them via email), so i could at least grab them and copy them over?

Thank you

@all

This was the problem...
I never got an "error", just a simple line at the end of the build process telling me

I redid all of it with -j2 and it worked...finally :-/

Now i have more questions, but i'm returning to my "Porting to..." thread instead to not spam @kas1e's thread
