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
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.
