It seems to me, you pass invalid address to bind().
InternetAddress takes ipv4 dot notation string x.x.x.x, and
for bind you are to supply INADDR_ANY
For DNS resolution:

Right, but in this case, it would be sufficient to bind socket to
INADDR_ANY.

nope. compiler knows about this special pseudovariable, and will not
generate code neither for condition, nor for ctfe branch.

__ctfe is a constant, though. Any half-decent optimizer will throw away
the path that's not taken. dmd does it even without the optimization

CTFE rounding can be more simply done using cast(int), although
for negative numbers the behavior is not the same.

It comes up frequently in PVS Studio's open source analysis write ups. So I checked for all the languages listed: C, C#, Java, Javascript, C++, PHP, Perl and D. All have the same order of precedence except, as always the abomination of all languages: C++ (kill it with fire). C++ is the only language that has the ternary operator have the same precedence than the assignment operators. This means a>=5?b=100:b=200; will compile in C++ but not in all the other languages. That's one reason why it irritates me when people continuously refer to C and C++ as if it was the same thing (yes I mean you Walter and Andrei). Even PHP and Perl got it right, isn't that testament of poor taste Bjarne?. :-)

While you are linking with the phobos you compiled yourself with -defaultlib, ldd (and your binary) will pickup the one available in one of the paths configured for the run-time shared library loader. To actually make use of the phobos you compiled you also need to set the rpath. ``` -L-rpath=/path/to/phobos ``` Or use phobos as a static library. -- Mike Wey

That's a little trickier when things are spread over more than one repo and dub is involved. Hopefully I should have dcompute kernels running on OpenCL 2.x very soon.
