There are two main libraries in D: The D Runtime, and the
standard library (a.k.a. Phobos)
By default, D links in Phobos and the D Runtime. With the GDC
compiler, the two are actually compiled as a single binary. You
can disable linking phobos and the D Runtime with the
-nophoboslib compiler flag. I'm not sure if DMD or LDC offer a
similar compiler option. You could, however, compile to object
files and then link manually with the system linker to avoid
linking in phobos and the D Runtime.
If you don't explicitly import anything, then you won't need
phobos, but you may need the D Runtime depending on which
features of the language you use. However, if you stick to a
C-like subset of D, you need very little of the D Runtime (50~100
lines of code)
Note: since, I'm already here, does anyone know how D
manipulates/uses standard streams to make its write/read
functions as well? I can't find any resources telling me a
non-abstracted way of this being completed.
It is my understanding that D links in the C standard library and
leverages the functionality there for standard streams.
