Zeoslib - can't compile and install

Hi,

i am using Zeoslib 6.6.6 and Lazarus IDE v0.9.31 build 34014, FPC
2.5.1 on Windows 7. When i download same Lazarus version but FPC
2.4.4, all works OK.

But it doesn't work on FPC 2.5.1 - it returns this error compilation
message:
Code:
[Select]C:\lazarus\komponenty\zeoslib\src\core\ZClasses.pas(84,22)
Error: No matching implementation for interface method
"IUnknown.QueryInterface(constref TGuid,out <Formal type>):LongInt;
StdCall;" found

on the line 84 is:
Code: [Select]  TContainedObject = class(TAggregatedObject,
IInterface)
Can anybody help me? It seems that FPC 2.5.1 has changed syntax in
some way.

IUnknown.QueryInterface has changed. It uses now constref iid:tguid.
Before it was const iid:tguid.

CodeTyphon has updated zeoslib 6.6.6 for use with 2.5.1. I'm using
that version without any problem with lazarus svn and fpc.

Who is CodeTyphon and where can i find that version, please?

Exactly the same happens under FPC 2.6.0. I will try the mentioned fix
and report.

I Installed the ZeosLib version from CodeTyphoon, and it works.

I don't know how "alive" the ZeosLib project still is, but an official
fix would be great!

Revision 967 works with FPC2.6.0 for Mac OS X 10.6

Revision 967? Where? CodeTyphoon, or the official project page on
SourceForge.  I downloaded 7.0.0 alpha from there, and the same issue
is still there. 

Surely the code modification required should be minor - if someone
could just post it...

Also you have to modify plain files for the dynlib. Here is the path
you can reach in
/zeoslib/trunk/src/plain
Thanks.
