Homebrew package

[easybe]

I would really love to be able to install this awesome toolchain with brew without having to compile everything.

Here my first attempt to create a Homebrew package (requiring https://github.com/autc04/Retro68/pull/85):

https://github.com/easybe/homebrew-core/blob/retro68/Formula/retro68.rb

I guess we won't be able to have Apple's Universal Interfaces as part of the binary package though.

Anyway, currently the install fails here:

Any idea what is going wrong?

[autc04]

Strange.

Looks like it tries to build the apps in TestApps before it builds the runtime library, libretrocrt. Which is strange, since those apps should probably link to libretrocrt.

The C compiler should automatically try to link to libretrocrt, so I haven't been telling CMake to link to libretro. But in add_application.cmake, linbe 81, the add_application macro tells CMake that linking an application requires the libretro target to be built first. Is this not working any more?

[easybe]

brew install --verbose --debug https://raw.githubusercontent.com/easybe/homebrew-core/retro68/Formula/retro68.rb

[autc04]

I'm on it. It is indeed a problem related to the order things are built in (no idea yet why that stopped working), and there also seems to be another problem later on:

In file included from /tmp/retro68-20190812-4702-3w0zzt/Retro68-0.0/LaunchAPPL/Server/OpenTptStream.cc:28:
/usr/local/Cellar/retro68/0.0/CIncludes/OpenTransportProviders.h:2333:5: error: 'FSSpec' does not name a type
 2333 |     FSSpec      modemScript;
      |     ^~~~~~

... probably related to the exact UniversalInterfaces version being used.

[autc04]

I'll probably have some more time to look into it this evening.

[autc04]

Try again now. I've fiddled with the build order stuff and worked around the OpenTransportProviders error.

[easybe]

[autc04]

Okay... this time, we're having a Universal Interfaces problem.

The package you are downloading doesn't include the 68K OpenTransport libraries (OpenTransport.o) that mine contains. Mine's a version of 3.4 from somewhere, I'll try to track down my source tomorrow.

The good news is that we're already at the "optional" parts of Retro68 (well, the parts that could be made optional should anyone want to add the necessary pumbing to the CMakeLists and build-toolchain.sh files).

[easybe]

Cool, we are getting there 😄

Actually, I have successfully built everything with the Universal Interfaces from MPW GM recently. MPW used to be available on Apple's FTP (which IMHO would be the preferred source) and can still be downloaded here. Using something that can be found in https://staticky.com/dl/ftp.apple.com/developer/Development_Kits/ just makes the most sense to me though.

[autc04]

So apparently, the OpenTransport 68K libraries weren't part of the Universal Interfaces package, they were just distributed with MPW. Interestingly, the PPC versions of those libraries are more likely to be included, probably because 68K .o files were specific to MPW, while PPC .o files actually followed a documented standard format (IBM's XCOFF).

There's a separate OpenTransport SDK available as well.

So I think our options are...

• Use MPW GM interfaces instead
• Download both Universal Interfaces and the OpenTransport SDK
• Don't include pre built Samples and LaunchAPPLServer in the homebrew package
• Make the build not fail if OpenTransport libs are missing (#88)

[easybe]

OK, got the build to work now 🍾. Thank you very much for the support.

Next step would be to create a version tag/release of this repo. Would that be possible?

Further, I will try to find a good way to not have the files form Apple in the binary packages/bottles. I think this should easily be possible by implementing post_install. Worst case we have a script that the user has to run after brew install.

[easybe]

Please review https://github.com/autc04/Retro68/pull/89. Cheers.

[easybe]

Thanks for merging https://github.com/autc04/Retro68/pull/89. I would also add an option to build-toolchain.bash to remove the interfaces and libraries after the build. What do you think?

[autc04]

Yes, unless you'd rather do that in the build formula. If it's in build-toolchain, it should probably be documented as being "for use by packaging scripts".

[autc04]

I've played around a bit more with the interfaces-and-libraries.sh script. I've made it store a list of installed library files in $PREFIX/apple-libraries.txt, and I've added a function removeInterfacesAndLibraries() that removes all libraries.

One minor thing that I'll probably take care of tomorrow is the fact that build-toolchain copies the PEFBinaryFormat.h header from the universal interfaces because that's needed for the host side tools to build.

[easybe]

Cool, thank you very much. I will make use of it in the Formula.

BTW, now we have a mix of spaces and tabs. I do not really care which one we use (but prefer spaces) but it should be one or the other.

[easybe]

I've updated the Formula. Building now...

[autc04]

Something is still going wrong... I broke something, and just pushed a fix. Also, I noticed that apparently homebrew's cp_r command does not copy old-fashioned resource forks with the libraries (which shouldn't really be a problem, as there's a fallback, but if you know an easy way to fix it...)

[easybe]

I‘ll use cp -r instead. I do not know if Ruby can do that. Maybe the experts that will review it will have a better solution...

[easybe]

So, build was successfully now. But, when trying to build my application I got:

1:1: error: could not open /usr/local/Cellar/retro68/0.1/m68k-apple-macos/RIncludes/Retro68APPL.r

[autc04]

Oh...

I didn't think of that. The cmake build (in libretro/CMakeLists.txt) installs Retro68APPL.r into RIncludes, but my "remove apple interfaces" implementation removes all files in RIncludes. I'm going to bed for today, no idea how much time for this I'll have in the evenings during the week, but it shouldn't take long to come up with a fix for this...

[easybe]

Please review https://github.com/autc04/Retro68/pull/90.

Just brewed it again. I can manually build a sample without problems. However, I can't run brew test:

  brew unlink gcc

To force the link and overwrite all conflicting files:
  brew link --overwrite retro68

To list all files that would be deleted:
  brew link --overwrite --dry-run retro68

I have gcc 9 installed as a brew bottle. And apparently, gcc 9 installs quite a few files into the retro68/ prefix that conflict with the non-crosscompiler version of gcc 9. For now, the formula should probably be keg-only.

[autc04]

Okay, after unlinking gcc and brew link retro68 I can run the tests...

The problem seems to be that brew pollutes the environment with lots of environment variables, most importantly CFLAGS and CXXFLAGS, that get picked up by cmake but that are incompatible with non-Apple compilers. Not sure if we should just add exporrt CFLAGS= CXXFLAGS= to the test, or whether something else should be done in the long run.

[easybe]

Thanks for the hint. Got it to work.

Could you create a release/tag now? Then I can finish the formula and create a PR. Cheers.

[autc04]

v2019.8 is tagged.

[easybe]

Thank you very much.

I think I'm getting there. Unfortunately, I found a last small blocker for the package: https://github.com/autc04/Retro68/pull/91

We will need another tag. Or, you could also re-create/move v2019.8, both works for me.

[autc04]

There's v2019.8.2 now.

[easybe]

OK, https://github.com/Homebrew/homebrew-core/pull/43442, let's see what happens...

[autc04]

Great!

[easybe]

For some reason the builds failed on Jenkins 😞

https://jenkins.brew.sh/job/Homebrew%20Core%20Pull%20Requests/version=high_sierra/47122/console https://jenkins.brew.sh/job/Homebrew%20Core%20Pull%20Requests/version=sierra/47122/console https://jenkins.brew.sh/job/Homebrew%20Core%20Pull%20Requests/version=mojave/47122/console

Also, regarding the feedback we got it looks like we cannot install the interfaces in post_install. However, I have an idea how to still make the package easily useable. I will create a PR in this repo.

[autc04]

The formula really needs to depend on bison, as Apple only includes bison version 2. The error message was very well hidden in the middle of the log, because Rez used to be optional. And that's now bug #92.

It looks like we might need to do two things:

1. Make installing interfaces after the fact more convenient, maybe by installing the relevant scripts along with the other stuff.
2. Allow building the whole thing without Apple's interfaces at first.

The problem with 2. is that the libretro runtime library as well as the RetroConsole library need them, of course.

I've started looking at how to use the executor source code to rig up a replacement for the the most important parts of the UniversalInterfaces. That would be incomplete, but it would be based on a clean-room reimplementation, so it could be included. But don't expect anything from me on that front before a 2019.9 version, or even later...

1. That is what I am working on
2. I do not know if that is necessary

[easybe]

OK, so they rejected the PR and suggested to create an own tap. Still, I will finish the changes I had in mind and then look into creating an own tap.

[autc04]

Too bad. In the meantime, I'm making some progress with my "Multiversal Interfaces" project. It's not enough to compile Retro68 yet, but I am now convinced it can get far enough to be at least a good place to start for people who install Retro68. The original Universal Interfaces can then be made optional.

I am working on following tap now: https://github.com/easybe/homebrew-retro68

Unfortunately, when building with Azure Pipelines on macOS 10.14 I get following error:

I get the same on by machine which runs macOS 10.13.

I haven't built this often enough on my Mac recently... It looks like a case-insensitivity problem related to threads.h (a newlib header) and Threads.h (an Apple header), which can't exist in the same directory on a Mac. I thought I had fixed this with commit 57d99dfbed28d62e0ab054b600830d633f540ad4, did I mess that up?

[autc04]

Yes, I did. Should be fixed with 92c055052661235ca49c5addd568270778b6d004.

[autc04]

It should now be possible to build Retro68 without the Universal Interfaces :-)

[easybe]

That is good news, thanks.

I am on vacation at the moment. But, I'll see what I can do.

Would it also be possible to compile very simple test programs without the interfaces?

[autc04]

No hurry, just wanted to let you know, enjoy your vacation!

Definitely possible to compile test programs; in fact, all the included samples compile, only the LaunchAPPLServer is unusable due to missing features and a crash.

[easybe]

I tested it here: https://dev.azure.com/spam0686/spam/_build/results?buildId=58

But, using the --no-carbon option won't work. I would like to build the toolchains for all three targets. Is this not possible (at the moment)?

[autc04]

Yes, Carbon support just isn't there yet. It should be possible to get it to a level where it can build the toolchain and maybe even some of the samples, but we'll probably have to ask users to install the Apple interfaces for any serious Carbon development. Vacation coming up on my end, so don't expect anything before November.

[easybe]

I think that is fine. I have a patch to facilitate that. It would just be good if we could build the toolchain and have a simple test for it.

No hurry, enjoy your vacation. I'll be enjoying mine for another 2 weeks...

Sorry to bump, but is there any update regarding a homebrew package? Especially for TigerBrew.

I'm sure you know better than I do, but compiling this on a G4 is kind of painful. :) but I can't imagine it would be that difficult to make a tap for TigerBrew that would let one install a precompiled version.

Thanks!

Where I left off: https://github.com/easybe/homebrew-tap/blob/retro68/Formula/retro68.rb

It would have to be revised. Maybe switched to GitHub Actions.

However, building on/for PPC is a whole different story. There are most certainly no PPC-based runners provided by GitHub. And, I do not know if cross-compiling is possible.

        Cool, I’ll see what I can make of that. Thanks! I might set up my own build server if it becomes something I really am interested in.---- On Fri, 12 Nov 2021 01:33:18 -0500  Ezra ***@***.***> wrote ----

I could also donate some build server cycles if need be.

[easybe]

From reading http://maniacsvault.net/articles/powerpccross I understand that cross-compiling should be possible...
