Hi there!
I wrote a small utility library to read configuration parameters
from both command-line arguments (using std.getopt) and SDLang
files (using sdlang-d package).
The main library defines a struct ConfigParams whose fields are
themselves structs defined in sub-libraries (set as
dependencies), each responsible for reading one kind of parameter
(BindAddress, BindPort, etc) from both command-line and SDL
files. Each sub-library has its own unit tests which run
successfully in isolation.
Then, when putting everything together in the main struct
CofigParams I get the compile-time error:
/usr/include/dlang/dmd/std/socket.d(1195,9): Error: static
variable getaddrinfoPointer cannot be read at compile time
called from here: parseAddress(addressString, null)
while using std.socket.parseAddress to validate IPv4/IPv6 bind
addresses.
I'm using dmd v2.071.2 and dub v1.0.0.
The relevant piece of code where this happens is the following:
struct BindAddress {
import std.socket: parseAddress, SocketException;
// Private members
private string addressString = "0.0.0.0";
// Construct from address string
this(string addressString) {
try {
auto address = parseAddress(addressString);
} catch(SocketException ex) {
throw new BindAddressException("Invalid bind address " ~
addressString);
}
this.addressString = addressString;
}
}
As said, this works fine when tested in isolation, and the
compiler only complains when using BindAddress as a member of
ConfigParams.
Any idea what the problem may be?
Or is there maybe a ready to use, high-level library for parsing
parameters from command-line arguments and config files of some
kind?
