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,
Andrew

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) Copyright (C) 2007 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There is NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. "uname -a" yields: Darwin Andrews-MacBook-Pro.local 11.3.0 Darwin Kernel Version 11.3.0: Thu Jan 12 18:47:41 PST 2012; 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

Hi Andrew, I ran into this problem as well and here is how I fixed/hacked it: OSX Lion, and soon to be Mountain Lion, no longer come with GCC installed for the Command Line (/usr/bin/gcc) What you need to do is Install Xcode from the app store, which is free, and then: * Launch your Xcode 4.1 * Go to preferences > Downloads * Click on the "install" button near the "Command line tools" This will put gcc in your /usr/bin directory. Then try to recompile your code. -- the new mac installer on the website should probably come with gcc or check for dependencies Josh

Quick Edit: just noticed that your gcc command is working, so i guess this isnt the prob.
