The compiler's changed so I can't pass these on cmd line any longer, which means can't test compile for other platforms any more. This big problem for writing libs.

Please change back, or add override switch.

This just means you can't use the Windows version of DMD to test for Linux releases, and visa versa. You can't pretend to be using the 'wrong' version of DMD. In other words, DMD is not a cross-platform compiler - you have to use the version of DMD for the platform you are targeting.

Not true. I've used it for that also in past, and its worked fine.

I was talking about what applies *now*, not what you used to be able to do.

You may have to resort to a trick like this ...

<code>
import std.stdio;

version(NIX)   version=linux;
version(GATES) version=Windows;

char[] graf;

void main()
{
    version(linux)
    {
        graf = "linux rules!";
    }
    else  // <<< Don't forget the 'else'!
    version(Windows)
    {
        graf = "MS-Windows(tm) rules!";
    }

    writefln("%s", graf);
}

</code>

then compile it with ...
   dmd myprog -version=NIX

and

   dmd myprog -version=GATES

Wasn't it
version=windows
version=Linux

A small w and a big L.

(I'm not at a DMD computer right now, but I think that could be it.)

Nope, it was Windows and then linux,cygwin,freebsd,darwin,solaris...

Setting the OS versions was made illegal, that's why it doesn't work.

Used it for what?  Cross-compiling, or checking that the other-platform code is valid?

Preventing the user from doing the latter seems an arbitrary restriction.

Just wanted to mention the above works perfectly, as was stated. Very handy source example.

Thanks! :-)

Seems I remembered there was an inconsistency, but not what.

:-)   (Could it be that Walter is a Windows person?)   :-)

JTAI, if we're going to allow setting these predefined versions, then we ought to have a way of switching off versions defined for the local platform.
