A little while ago, there was a discussion about where to put the 32-bit phobos
library in the DMD archive. It was finally decided that the 32-bit version
would go to a lib32 directory, and the 64-bit one in a lib64 directory.
That's all fine for Linux, but I brought to the discussion that on OS X the
standard way is to create a universal binary which includes both architectures
in one file. That's how libraries are packaged on OS X. But I was told, that
this didn't concern OS X (yet) as the 64-bit port was (for now) Linux-only.
Valid point.
But now, I see that in the archive the OS X library has been moved to a lib32
directory. Was this intentional or is it an oversight? Is the plan to do things
as they're done on Linux and not have a universal multi-architecture binary?
Currently D for Xcode is broken by this change and I'm looking at the best way to fix it.
In the sort term I might just change the path to point to the lib32 directory instead of
simply "lib". But the current approach which is to put a symbolic link in
/usr/local/lib pointing to libphobos2.a won't work anymore if the binary for the two
architectures are kept in separate files...
I don't know what the right answer is.
The best thing would be to have a single multi-architecture library in a "lib" folder. Which would
mean going back to "lib" instead of "lib32".
And when the 64-bit version appears, you can easily combine the two architectures into a
single library file using the "lipo" command and let the linker handle things
from there on.
There's a conflict with the "mac way" and the "unix way". I'll have to agree
with Michel that on the mac we should do it the mac way.
