September 06, 2013 D Lang Socket Programming Example | ||||
---|---|---|---|---|
| ||||
Hi Friends, Socket programming with the D programming language is the most simple way how to do it For example, the sample with Tango, but not by phobos How do I do this with a simple, but phobos import tango.io.Stdout; import tango.net.Socket; import tango.net.ServerSocket; import tango.net.SocketConduit; int main() { Socket server = new Socket(AddressFamily.UNIX, SocketType.STREAM, ProtocolType.IP); while(true) { Socket client = server.accept(); char[1024] buffer; client.receive(buffer); Stdout.format("The client said'{}'.", buffer); client.shutdown(SocketShutdown.BOTH); client.detach(); } return 0; } |

I *think* if you replace that line with a UnixAddress: http://dlang.org/phobos/std_socket.html#UnixAddress It will do the trick. (I say *think* because I've never actually used a unix socket with D, so I'm not entirely sure.) |

Meaning that domain/Unix sockets aren't available at all in D (or need to be done through C calls directly)?

Thanks acehreli
In the example you give, but I receive this error during compilation.
savsak:~ savsak$ dmd /Users/savsak/Desktop/test.d
ld: library not found for -lphobos2
collect2: ld returned 1 exit status
--- errorlevel 1

That has already been fixed in the version of Phobos on Github (I've marked it as fixed now, didn't know about that issue on bugzilla before).

Your dmd installation is broken. Please tell how have you set it up to get any fixing suggestions ;)

Also note that probably /usr/lib would be more efficient as search path but using /usr can also catch exotic cases like /usr/share). If your installation is OK you will find the paths told by the find command to match those in /etc/dmd.conf. Here is an example of a working installation: $ find /usr -name 'libphobos2*' /usr/lib/x86_64-linux-gnu/libphobos2.so /usr/lib/x86_64-linux-gnu/libphobos2.a /usr/lib/i386-linux-gnu/libphobos2.so /usr/lib/i386-linux-gnu/libphobos2.a /usr/lib/i386-linux-gnu/libphobos2.so.0.2 --------------- $ cat /etc/dmd.conf // ... some comment lines ..
