digitalmars.D - Dropping support for OSX 32 bit

reply Nicholas Wilson <iamthewilsonator hotmail.com> writes:
So Apple has dropped support for 32 bit apps in the latest OS 
release (September last year).

Officially we support 10.9 (Mavericks) released October 2013. All 
supported versions run on 64bit processors, Apple support (I 
think?) 10.11 and newer (we should probably raise that to be in 
line but thats a different problem: see 
https://forum.dlang.org/thread/CAOC+-J-iZnpvEvFu5womjuy2H_ZiUzPytVDZfxoPuv1zYt173g mail.gmail.com).

The newer c++ standard library support is disabled on the 32 bit 
configurations of the CI pipeline and is currently blocking 
https://github.com/dlang/dmd/pull/9143

Removal of support has been requested 
https://github.com/ldc-developers/ldc/issues/2959
and by many who have experienced the ~~joy~~ pain of dealing with 
CI failures related to OSX32.

1) Does anyone actually build for 32bit OSX?
2) Is everyone happy with accelerating EOL for D support of OSX32?

Please reply so we can get a representative sample.

I spent a lot of blood and sweat getting OSX32 to work, and I hate to say it, 
but it's time to drop kick it to oblivion.

If only you could drop unsupported C++ compilers and linkers (for 
far longer) as easily :/.

Thanks a lot for opening this thread!

It has been quite a pain for many D contributors as this target 
never received much love and thus is probably the one with the 
most "random" bugs in it and I remember quite a few times where 
contributors had to waste hours trying to workaround the 
auto-tester 32-bit OSX build as they couldn't reproduce the error 
locally.
Also, if we remove support for it, the OSX builds on the 
auto-tester will receive a doubled capacity.

So, as our resources and manpower are stretched thin, I think we 
should focus on targets that are actually being used and I 
suggest to drop support for it.

No, at SARC we don’t.

According to this [1] El Capitan (10.11) is not supported any more. 
Unsupported as of August 2018 and iTunes support ends this year.

As far as I know, the only one was Guillaume Piolat (p0nce) which has 
now requested the support to be dropped [1].

Yes. Please kill it.

Yes, eventually, at some point.  Sometime over the next month, 
I'll be adding druntime support for 10.5, as its the only version 
that fully supports all architecture combinations for darwin 
(x86, x86_64, ppc, ppc64).  For bootstrapping, it's easier to 
start at the most common baseline.

So long as druntime C bindings are left intact - all rt stuff 
regarding OSX support not compiler agnostic anyway - dmd compiler 
is fine to do what it wants.

I think the point is to allow PRs that may break the OSX 32-bit build. I 
don't think there are any plans to remove the current support.

In other words, I think it will continue to build and function, but 
nobody will be testing it. So it may break in the future.

And add me to the list of those who do not use (actually never used) 
32-bit OSX. And I've been using macs since 2012. I'm fine with removing 
support.

We are using D with OSX at DeepGlance, but not on 32bit platform.

Feel free to kill

No, and we can use old compilers if need be.

Drop it.
Being friendly to those core developers matters a lot.
Everything is moving faster and faster, the rolling release 
things are examples.
