Is there a way to compile a project and deploying it as a

A default build of a D program is *reasonably* compatible. All
its dependencies are core operating system components like
libc. Now, there can certainly be libc version
incompatibilities, but there's a decent chance it will just
work.
I'm pretty sure this is the exact same situation Go is in; the
default Go and D builds link the same way.
I was curious so I just tried. Building a hello world with "go
build" (I just litterally did what was on
https://gobyexample.com/hello-world) produces a file that is not
a dynamic executable. There is no dependency.
For comparison building a similar hello world with dmd and no
options gives the followig dependencies (thanks ldd):
linux-vdso.so.1 (0x00007fffd02aa000)
libpthread.so.0 => /usr/lib/libpthread.so.0
(0x00007f45e5e69000)
libm.so.6 => /usr/lib/libm.so.6 (0x00007f45e5b1d000)
librt.so.1 => /usr/lib/librt.so.1 (0x00007f45e5915000)
libdl.so.2 => /usr/lib/libdl.so.2 (0x00007f45e5711000)
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1
(0x00007f45e54fa000)
libc.so.6 => /usr/lib/libc.so.6 (0x00007f45e5142000)
/lib64/ld-linux-x86-64.so.2 =>
/usr/lib64/ld-linux-x86-64.so.2 (0x00007f45e6087000)
(And using -L-static produces an error because of an
incompatibility with -pie... I'm sure it's workable I just didn't
take the time to look it up yet)
