Support on macOS (via Homebrew)

[mavam]

Great project! It would be really nice if we had support on macOS via Homebrew, allowing users to install Diagon via brew install diagon.

Is there anything that would prevent a build on OSX in principle? I tried to build it on OSX Big Sur 11.6 with Apple Clang 13, but no success with a first shot:

[ArthurSonzogni]

Thanks!

The first error is probably fixable by replacing the line with:

        std::cout << "  [PASS] " << test.path() << std::endl;

The second error is about a missing boost library.

I don't have a MacOS OS, but I tried to build it using github action here:
https://github.com/ArthurSonzogni/Diagon/runs/4610501448?check_suite_focus=true
Same errors.

If you want, you can try to make it work, and let me know if you managed to do it.
Here is the github action:

Diagon/.github/workflows/continuous-integration.yaml

Lines 41 to 46 in 0d4a89e

	#- name: "MacOS clang"
	#os: macos-latest
	#cc: clang
	#cxx: clang++
	#test: true
	#cmake: cmake

The part installing boost on MacOS

Diagon/.github/workflows/continuous-integration.yaml

Lines 77 to 79 in 0d4a89e

	- name: "Install boost for macOS"
	if: runner.os == 'macOS'
	run: brew install boost

[mavam]

The first error is probably fixable by replacing the line with

Yes, I just checked that.

The reason why Boost is not found is because Diagon doesn't use find_package in the CMakeLists.txt to properly setup the dependencies. If that'd be there, CMake would find my existing Boost installation in /usr/local. Fixing this would probably get us macOS support for free.

[ArthurSonzogni]

Indeed!

If you want to give it a try on MacOS, I would merge the PR.
Otherwise, I will try myself this week end.

[DameonSmith]

Any update on this? I tried fixing it to use test.path() but then got this error. Not a C++ dev so I'm a little stuck.

[ArthurSonzogni]

I recently merged @iwahbe PR
#42

This fixes the test.path() among other.

[PythonicNinja]

Seems there has been some progress 🎉

Were you able to successfully build it for macOS?

[iwahbe]

My PR was brittle to upgrades in GCC version. See comments
#42 (comment)
and
#42 (comment)

That should do it.

[celie56]

I was unable to build with the latest code and saw a link error due to stdc++fs.
Removing this from the link targets allowed me to build on a mac m1.
My changes are here: #48

[ArthurSonzogni]

Update:

I am now able to build on the CI on Linux, Windows, Mac, WebAssembly:
https://github.com/ArthurSonzogni/Diagon/actions/runs/3509142920

I still need to tweak it a bit, so that I can extract the binaries produced from Mac and Windows.

[ArthurSonzogni]

It's done:
https://github.com/ArthurSonzogni/Diagon/releases/tag/v1.0.139

In the release, there are 3 assets for MacOS:

• diagon-1.0.139-Darwin.dmg
• diagon-1.0.139-Darwin.tar.gz
• diagon-1.0.139-Darwin.zip

I don't have a Mac. Could someone try one of them to confirm this is working on Mac?

What are the next step to publish it to homebrew?

[celie56]

Running the binary does not work on my system. Building from source for v1.0.139 does work. So good job there.

Here is what I saw when running the binary.

It could be a problem with my setup, but I have boost installed via homebrew and it seems to work fine when building from source 🤷

[RobertAudi]

One problem I see straight away is that homebrew now installs everything under /opt/homebrew and the boost prefix is /opt/homebrew/opt/boost not /usr/local/opt/boost.

[ArthurSonzogni]

Thanks @RobertAudi & @celie56

I tried to link against boost statically. Unfortunately, there was a bug in Boost for MacOS:
Homebrew/homebrew-core#67427

Instead, I removed the "GraphPlanar" translator from MacOS for the moment.

Does it fix the problem?

New builds:

• diagon-1.0.139-Darwin.dmg
• diagon-1.0.139-Darwin.tar.gz
• diagon-1.0.139-Darwin.zip

[celie56]

Those links appear to be broken.

[ArthurSonzogni]

I removed the previous draft prerelease. It is no more available. However the last links should be working.

[RobertAudi]

@ArthurSonzogni The links to the builds you linked in your previous comment are no longer available, or at least I get a 404 😕

[ArthurSonzogni]

Okay. It looks like I need to publish the release to make the link to work.

This is now fixed @RobertAudi and @celie56. See the links from:
https://github.com/ArthurSonzogni/Diagon/releases/tag/v1.0.139

[RobertAudi]

@ArthurSonzogni The new binary seems to work perfectly on my M1 🎉

[celie56]

Yep. Works on my machine too 👍
Thanks for the fix.

[ArthurSonzogni]

Awesome! Thanks for checking!

[mavam]

Double-confirming: same here! 🙌

I think the final swoop would be getting this now into Homebrew, which means writing a PR for https://github.com/Homebrew/homebrew-core.

[realshovanshah]

Looks like it's been a while so I'd also like to lend my upvote to the imminent homebrew support.

[fakkoweb]

Excuse everyone: how do I run it on Mac (M1) from the .dmg? All I get is something in bin classified as "document" so cannot really run it.

[realshovanshah]

Hey @fakkoweb! I'd guess everyone just copied the executable from the mounted directory to the desired location (and ejecting it, ofc) — /usr/local/bin works well for me.

Do you see no binary in the mounted dir?
