Hi all,
I've just installed DMD 2.058 and attempted to compile a 
little script
but was greeted with the following error:

gcc: Invalid argument

I used the .dmg installer from 
http://www.dlang.org/download.html and
issued the command:

dmd average

Is there something I'm missing?

Thanks,

Hi!

Could you try

        dmd -v avarage

and tell us what comes out?
Also, how does avarage.d look? Also what does

        uname -a

and
        gcc --version

say? Also, just in case

        which dmd

I made the mistake of assuming that gcc was automatically 
installed in MAC OSX. After installing Xcode the problem went 
away. To answer your questions though:

I'm using DMD version 2.058 for MAC OSX which I installed using 
the .dmg package available at 
"http://www.dlang.org/download.html";.

"gcc --version" yields:

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. 
build 5658) (LLVM build 2336.9.00)

"uname -a" yields:

root:xnu-1699.24.23~1/RELEASE_X86_64 x86_64

the average program is as follows:

[code]
import std.stdio: stdin, writefln;
import std.conv: to;

void main(string[] args)
{
   double sum = 0.0;
   int cnt = 0;
   foreach(line; stdin.byLine())
   {
      if(line.length)
      {
         sum += to!double (line);
         cnt++;
      }
   }

   double avg = sum / cnt;
   writefln("Average is %.5f", avg);
}
[/code]

and I doubt you want me to put all of what "dmd -v" spits out for 
this little script.

Thanks,
Andrew
