Howto detect os?

[Heertsch]

Hi
is there a way to detect, if the app runs under linux or osx?

Environment.OSVersion.Platform.ToString() sends in both cases "Unix"

Thanks
Andreas

In MD we use some detection code factored out of Managed.Windows.Forms/XplatUI:

I removed the GTK# reference and did some cosmetics (your code won't start on my VisualStudio) (see code below).
It works fine in Visual Studio and with MD on OS X.
But if I try to start it in MD with OpenSuse I get: (Back translation from German)
Error loading project foo.csproj: Could not set property 'Policies' in type 'DotNetProject'
No idea, what that means. (Probably it does not depend on the code below.)

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
namespace Basal.Code{
    public static class Platform{
        [DllImport("libc")]
        static extern int uname(IntPtr buf);
        static private bool mIsWindows;
        static private bool mIsMac;
        static private bool mIsX11;
        public enum OS {Windows, Mac, X11,unknown};
        static public OS GetOS(){
            if(mIsWindows=(System.IO.Path.DirectorySeparatorChar == '\\'))return OS.Windows;
            if(mIsMac=(!mIsWindows && IsRunningOnMac()))return OS.Mac;
            if(!mIsMac && System.Environment.OSVersion.Platform == PlatformID.Unix)return OS.X11;
            return OS.unknown;
        }
        //From Managed.Windows.Forms/XplatUI
        static bool IsRunningOnMac(){
            IntPtr buf = IntPtr.Zero;
            try{
                buf = Marshal.AllocHGlobal(8192);
                // This is a hacktastic way of getting sysname from uname ()
                if (uname(buf) == 0){
                    string os = Marshal.PtrToStringAnsi(buf);
                    if (os == "Darwin")return true;
                }
            }
            catch { }
            finally{
                if (buf != IntPtr.Zero) Marshal.FreeHGlobal(buf);
            }
            return false;
        }
    }
}

That shouldn't affect your code. It's just a warning from the project
loader. Could you file a bug with the full error message?

Yes your solution delivers also X11 for OpenSuse (if I use mono and not MD)

There could be more in the MD log at ~/.config/MonoDevelop/log
