Yeah, in the config it is

     // default switches appended after all explicit command-line 
     post-switches = [

I've hard coded it and it still doesn't find them.

I've added -conf=

and nothing...

dcompute\driver\cuda\package.d(3): Error: module `dcompute` is in 
file 'ldc\dcompute.d' which cannot be read

Of course if I manually include it then it gives more problems...

Seems ldc is not even reading the conf file or using it if it is?

If you are right then it seems you are suggesting it is an LDC 
bug... but that this is highly unlikely...

I am using Visual D and maybe it is all setup for dub and dub 
takes care of configuring something that Visual D does not?

Note that I've had to include the dcompute imports(downloaded 
from git), rt(for xmalloc I think), and derelict modules.

I did those because when I added dcompute it would complain about 
the missing modules so I had to hunt and peck to find them.

When I remove the ldc imports from Visual D,

then the error about missing ldc.dcompute is at

module dcompute.driver.cuda;
public import ldc.dcompute;

which, is in the ldc imports dir(which is why i manually included 
them which solves it then gives the intrinsics error).

In any case, it seems like it is a very strange bug since 
`pragma(LDC_intrinsic` should work fine. It's analogous to 
`pragma(msg` not working in dmd...

Are you using the latest ldc? (1.14.0?)
