digitalmars.D - Mac OS X 10.5 support

Currently, the build/test farm is OS X 10.7.

I don't think this is like the Windows issue. Upgrading Windows is (for me, 
anyway) a full day job. Upgrading OS X is inexpensive and relatively painless, 
the least painless of any system newer than DOS that I've experienced.

Hence, is it worthwhile to continue support for 10.5? Can we officially say
that 
only 10.6+ is supported? Is there a significant 10.5 community that eschews OS 
upgrades but still expects new apps?

 There appears to be fewer 10.5 users than 10.4, oddly:
 http://update.omnigroup.com/

Note that 10.5 and 10.4 support PowerPC as well as x86. They have 4% PowerPC, down from about 7% at the start of 2011. That accounts for about 25% of the combined decline of 10.4 and 10.5, and it's clearly caused by old machines being replaced. They must date from 2006 or earlier. Surely a large fraction of the remaining 10.4 & 10.5 systems are likewise near end of life. So it looks like: 48% 10.7 34% 10.6 15% 10.5 + 10.4 4% PowerPC, never supported by DMD.

While I'm normally big on not dropping support for older things, my honest take on it is that if someone's using an Apple OS, then they've already agreed to an implicit "contract" (for lack of a better word) that they're going to need to keep upgrading to whatever's the latest hardware/software anyway. It's just the way Apple works. 'Course, as a non-Apple user, I'm not sure anything I have to say on it counts for much. So, FWIW.

The link that Brad posted shows there are Intel users on 10.4 and 10.5. The number of 10.4, 10.5 users is about four times higher than the number of PPC macs. Is 10.6 still available? I would imagine that anybody who didn't upgrade early on, probably never will now.

That's too bad. But the same must apply to 10.6 as well, since the build/test farm runs Mac OS X 10.7. I mean it can cause problems as well since we don't have a build farm that runs 10.6.

Yes, except that no problems have arisen (so far!) with 10.6.

If anyone wants to give me a shell account on an osx 10.6 box (or 10.5 too for that matter), I'll be happy to setup and maintain the auto-tester on it. Feel free to shoot me an email. Later, Brad

I have a project that we actually plan to use in production in the company for which I work.

If support should be dropped anyway, are the issues only build-related so that e.g. gdc would still continue work on 10.5 without further work?

Would it also be possible for you to: 1. debug what has gone wrong with the 10.5 support? I'll be happy to fold in any resulting patches. 2. provide a remote login shell so we can figure it out? 3. use git bisect to determine which change broke it?

I will try and see if a regular retail version of 10.5 can somehow be run in a VM, I will possibly get one tomorrow. Otherwise I'll try to get a 10.5 test machine on monday and see what I can do.

I was able to test on a Mac Mini with 10.5 today (setting up a virtual machine did not work without downloading disk images over torrent or similar stuff and v4.1.1 of vmware fusion does not allow non-server installations anymore). My findings were: - stock DMD did not run because it is compiled for 64-bit while the system is 32-bit only - compiling on a 10.6 machine with stock DMD caused a fatal dyld error at application startup on the 10.5 machine (for a simple hello world app) - compiling a fresh DMD on the 10.5 machine from git seems to yield working executables So either the problem is just a build setup issue or it was something I didn't test (I tested writefln() as in bug 4854). Is there a standard way to build the DMD+druntime+phobos package so I can simulate the original build process? Right now I just compiled each of those separately using "make posix.mk" without any further options. Minor note: the version check in dmd/source/posix.mk to select the OS X SDK does not work on 10.5 and it selects the 10.6 SDK.

Attached the patch (the pattern uses % instead of * and the 10.5/10.6 arguments are reversed on line 40). There is an easy way to install the 10.5 SDK on a 10.7 machine: http://lunokhod.org/?p=269 Maybe that would be a viable solution to keep 10.5 support - of course assuming that it's really just the SDK.

You don't actually need the 10.5 SDK to create a 10.5-compatible binary, unless you're compiling for PowerPC. All you have to do is use the "-mmacosx-version-min=10.5" argument when invoking GCC and make sure you're not using any API not present on 10.5 (and if you're using one it'll be weak-linked and you have to check at runtime if it exists before using it). You can still use the 10.6 or 10.7 SDK, or not specify any SDK letting the compiler use the system-installed headers and libraries. I'm doing it with my apps, and it works great. -- Michel Fortin michel.fortin michelf.com http://michelf.com/

 You need 10.5 server. Apple doesn't allow desktop versions of OSX in a VM (I

may be able to sort out earlier OSX server versions somewhere for my own use,
but I don't have the resources to make them accessible to others.  I'll see
about trying this today.

VMware made a mistake with VMware Fusion 4.1 that allows to virtualize Leopard and Snow Leopard. http://www.macworld.com/article/163755/2011/11/vmware_fusion_update_lets_users_virtualize_leopard_snow_leopard.html -- /Jacob Carlborg

 Lately, dmd seems to have broken support for OS X 10.5. Supporting that
 system is problematic for us, since we don't have 10.5 systems available
 for dev/test.

 Currently, the build/test farm is OS X 10.7.

 If support should be dropped anyway, are the issues only build-related so
 that e.g. gdc would still continue work on 10.5 without further work?

Maybe... someone needs to test it though (apple-gcc won't work anymore as that has been dropped, but gcc should still be available through macports, or so I'm told). --=20 Iain Buclaw *(p < e ? p++ : p) =3D (c & 0x0f) + '0';
