No-one?? This bug is particularly annoying because it prevents me from
calling ntohl, ntohs etc from within a class method. In the end I just
wrote my own ntohl functin and called that.

Reply to Regan,I don't known why your getting it, but you must have more than one ntohl defined. The linker is finding this so I expect that one is in a lib. Try dropping the pragma (lib) and explictly linking c:\dmd\lib\WS2_32.LIB directly.Error 1: Previous Definition Different : _ntohl 4 --- errorlevel 1 Anyone know what this means?No-one??

Looks like a phobos problem. ntohl can be found in both phobos.lib and wsock32.lib. If you don't link with wsock32.lib, the error relating to ntohl goes away (and creates other problems). std.c.windows.socket has its own version of ntohl. It should either be a unique name or refer to wsock32.lib. Dick BCS wrote:Reply to Regan,I don't known why your getting it, but you must have more than one ntohl defined.

Can you check if std.socket already has pragma(lib) ?

Ok... It does not.
In fact "pragma" is not used in phobos at all.
