I'm familiar with building DMD/Phobos on linux32/64 (and I assume
freebsd is much the same, aside from having to install GNU make), but I
know OSX is different in that the 32/64-bits bins are combined. I don't
have access to a modern OSX machine ATM, but I might have a little
bit of time with one tomorrow (I'm pretty sure it's either 10.6 or 10.7
- I know it's a Core i7 laptop FWIW).

So I wanted to ask, is there anything I should know about doing a full build of DMD/Phobos on OSX? Is it just like doing a 32-bit-only or 64-bit-only build on linux, but just without using -m32/-m64? Or do I do one arch and then the other? Or does it differ between the different components (dmd/druntime/phobos)? Etc. And are there any special OSX-only prerequisites?

Both of these should be fine and are modern enough for developing using DMD.

If you run "make -f posix.mak" it will build only build for the default architecture, that is most likely 64bit. Only 64bit binaries of DMD are distributed. For Phobos a universal (fat) binary is distributed. Search for "lipo" in the Phobos makefile. lipo is the tool used to combine multiple architectures to a single binary. You can verify the result by running "file path/to/binary". It will tell which architectures are available in the binary. These tools work both with executables, dynamic and static libraries.

The developer tools, aka Xcode, available in App Store.

Thanks, I was indeed able to compile DMD/phobos on the system (after a loooong and surprisingly non-trivial download and install process for xcode/gcc).

There did appear to be an issue with the tools repo, as I got errors about "dustmite" being a directory instead of a file, which kinda surprised me b/c I thought OSX was case-sensitive? (The tools repo *does* have the dustmite sources in a subdirectory named "DustMite".)

Oh, really? I guess I forgot to mention that you need to install the command line tools as well.

No, HFS+, the filesystem on Mac OS X, is by default _not_ case-sensitive. I have hit one or two issues with this but in general it's not a problem. If you want, it's possible to choose case-sensitive, but that would most likely require you to reinstall the system.

Actually, what really took the most time by far was just downloading xcode - that sucker's like 1 or 2 gigs!

All in all that wasn't too bad though. The most awkward thing about the whole deal was just using an OS that I'm *really* not accustomed to ;)

I see. In that case, the "tools"'s posix.mak needs to be fixed, ideally by generating the executables into a subdirectory instead of tools's root. I'll put together a pull req.

You can actually just download and install the command line tools. But I'm not sure if the DMD makefile is setup to handle that. I have know idea if it will find the SKD and so on.

They're available here:

https://developer.apple.com/downloads/index.action

Requires a free Apple account. Search for "Command Line Tools". Only 113 MB.

Hehe :)
