digitalmars.D.learn - What is the equivalent of -version=Flag for conditional compilation in

Hi,

I was switching from dmd to ldc2 and would like to know the 
equivalent command line for conditional compilation -version=Flag 
I was using in dmd. I checked the ldc2 --help but didn't see 
anything relevant. Version there refers to compiler version or 
some other unrelated things.

Thanks

It's in there, I had to do grep to find it:

   --d-version=<level/idents>             - Compile in version code >= 
<level> or identified by <idents>

Thanks, I tried that but didn't realise I still had the old 
version flag in the command line and assumed it didn't work! Lol 
- silly!

You can also use `ldmd2` as driver for ldc2 with dmd commandline 
syntax.
