Bug 18603 – Illegal instruction: 4 on Mac OS 10.7.5 Leopard

After downloading version 2.079.0 of the Mac OS DMG file on a Mac OS 10.7.5 system, the installer runs OK but the files it leaves in /usr/local/bin (e.g. dmd or dub) all say "Illegal instruction: 4" when you try to run them. This is despite the fact that the installer says it aims at Mac OS 10.6 or above. I suspect the files have been compiled with a Mac complier that targets a minimum version of Mac OS higher than 10.7 (perhaps 10.9 or higher?) - if this cannot be fixed, perhaps the minimum Mac OS requirement needs to be updated? Thanks. (Filing against Installer because I'm not sure which component this should be filed against. Hopefully it's easy to reassign if necessary.)

Yes, the minimal deployment target was bumped to 10.9 with 2.079 See: https://dlang.org/changelog/2.079.0.html#osx-10_9 So I guess the only thing we can do is update the docs. I see that this page (https://dlang.org/dmd-osx.html) still says 10.7, did you see another one?

There is also a reference to 10.6 in the installer itself. It says "This package is intended for Mac OS X Snow Leopard (10.6) and later" on the "Welcome to the DMD2 Installer" screen.

I don't use OS X, but it seems like this should do the deed: https://github.com/dlang/installer/pull/308 BTW 2.078.3 should still run on 10.7
