Hello,


is it possible to have something like this in D (in a context where I am interfacing with C code)

version(32Bits)
{
version(Windows)
{
...
}

version(MacOs)
{
...
}
}

version(64Bits)
{
version(Windows)
{
...
}

version(MacOS)
{
...
}
}


how do I tell the D compiler to compile the 32Bits and MacOS version code ?


Best regards

Pac

To start with, I don't think version identifiers can start with a digit.  You'll have rename them.

As for your question, you can either specify "-version=_32Bits -version=Windows" on the DMD commandline, or, in the source code, you can say "version=_32Bits;" to define a version flag.

Is there any way to "deregister" a version?

e.g. I am in a Linux environment and don't want to include the "version=linux" parts.
