• David Nadlinger (9/13) Oct 22 2013 That's with LDC, right?
• bioinfornatics (8/22) Oct 22 2013 yes with ldc. I do this command

Hi,

That is now some time where i am not try to buld derelict3, 
Currently my build fail with:

derelict/pq/types.d(117): Error: struct derelict.pq.types.PGconn 
unknown size
derelict/pq/types.d(117): Error: struct derelict.pq.types.PGconn 
no size yet for forward reference

Someone know what to do?

thanks

That's with LDC, right?

We definitely need to improve the error message (it should refer 
to the actual function definition), but I checked the Derelict 
source a few weeks back and if you grep it for PGconn, you'll 
find that it is used in a function parameter (for which the 
actual type is needed for the x86-64 ABI handling code).

If you don't need that function, just comment it out.

yes with ldc. I do this command
find -iname '*.d' | xargs grep -Hn PGconn

and i see like you that is a alias to a function i do not use 
this syntay usually so i am not able to understand what is the 
problem.

So i build for both 32 / 64 bits, i think i need it no?

I'm not on my dev box right now, but I took a look at the source 
at github and found what I'm certain is the cause of the problem. 
PGConn is an opaque struct, which means instances can only be 
declared as pointers. However, the declaration of 
PQsetErrorVerbosity in functions.d incorrectly declared a 
parameter of type PGConn rather than PGConn*, hence the forward 
reference error.

I've edited the file via the github interface, so I'm not able to 
attempt a build at the moment and won't be for a few hours yet. 
But I 99.9% confident all should be well. I was unable to find 
any other incorrect declarations of PGConn parameters.
