"libphobos2.so" for OSX is not yet available. You should use "libphobos2.a".

libphobos2.a is not compiled with PIC code on Linux and OSX so is not usable for creating shared libraries, it has to be libphobos.so.

Uurrr… on what grounds?

Shared libraries are simply not yet supported on OS X, at least not to the same level as on Linux.

PIC is the default on OS X. But as David said, dynamic libraries are not properly implemented on OS X yet in DMD (or any other D compiler).

Sponditious.

They work for me fine on a MBP with OSX Mavericks.

However on a white MB with OSX Lion (*) the install of DMD fails. The problem appears to be that Clang cannot link the object files since the object files are not built for x86 architecture – despite the processor being 64-bit, the boot prom is 32-bit and so OSX is 32-bit and reports the processor to be 32-bit, unlike the processor which knows it's 64-bit and reports so. As far as I can tell (log files are huge due to the huge numbers of warnings about expressions) all the clang++ lines have -DDM_TARGET_CPU_X86, so I am somewhat surprised. Of course I am really a Linux person being forced to set up OSX boxes for testing…

I think this is a core problem for D in general: everyone needs or wants shared libraries, but…



(*) Apple refuse to allow any upgrade of this hardware to OSX Mountain Lion or OSX Mavericks, so I am stuck with OSX Lion.

I have no idea how Macport compiles DMD but I have no problem in compiling DMD manually, either with a 64bit or 32bit kernel.

If the computer supports it, you can force OS X to boot either a 32bit or 64bit kernel [1].

I'm pretty sure there are ways around that.
