I import std.stdio;

and
writef("Hello");

gives me:

 Error 42: Symbol Undefined _D3std5stdio6writefFYv

when linking!

And i really wanted to figure out how this writef works!

linux or windows? And is the 0.95 library installed?

WindowsXP, i did what i allways do: extract the new zip over
the old ones. The strange thing is that there is a _D3std5stdio6writefFYv
string in phobos.lib.

I just tried deleting my dm and dmd directories, an re-extracted the zip, and now it compiles and links, but when i run it i get "Test.exe is not a valid Win32 executable"

It may be that i am a little tired and doing something wrong, i'll try it on the other computer tomorow! :)

I tried it on the other computer and it works(sort of).
writefln does work ok
writef doesn't print anything with the same arguments!

I think this will be fixed when TypeInfo gets better, but right now:

date_t t = /* something */;
writef("%s",t);

Outputs the numeric representation of the date.

try an fflush(stdout) after the writef.

That works but that way i have to import both
std.c.stdio and std.stdio! I think i'll just stick with
the writefln (it is really nice by the way!)

The flush is triggered by the output of '\n' when writing to a 'tty'. I'd just remembered that <g>, which is why the writefln worked for you. The output from writef will eventually appear. In fact, the behavior is the same as if you used a printf without a '\n'.

What about this?

//////////
import std.date;
import std.stdio;
import std.c.stdio;

void main ()
{
    writefln("hi");
    fflush(stdout);
    d_time t = getUTCtime ();
    while ( getUTCtime() - t < 2 ) {}
    writef("bye");
}

//////////

Both "hi" and "bye" get printed at the same time (2 secs after the program
started). Tested on WinXP Pro and Win95 (yes, I'm currently using also 95).

Windows is a multithreaded operating system, and while your program is hung in a tight loop, it is probably preventing other threads from running, like the thread that updates the console window.
