[Lazarus] package FCL

[Antonio Fortuny]

Hi Folks.

I want to make some changes and additions to the unit bufdataset.pas 
incresing dataset possibilities.
I've made the changes, compiled and tested using a dynamically created 
component.
So far, so good.
Now I want to incorporate the changes in the FCL package fcl-db
Vista32, Lazarus 1.0.10, FPC 2.6.2
Compile FPC fcl-db package, and compilation runs OK and my new unit gets 
compiled (see below for console output)
BUT
new .o and .ppu are not moved to 
"D:\Programmes\lazarus\fpc\2.6.2\units\i386-win32\fcl-db\"  but are kept 
in 
D:\Programmes\lazarus\fpc\2.6.2\source\packages\fcl-db\units\i386-win32\ 
as compilation result
Secondly, I guess that the Lazarus pacakge FCL should be compiled as 
well. The unit RegisterFCL does the TBufDataSet component registration
This one also looks good.
Then I install the FCL package and rebuild Lazarus. During Lazarus 
compilation all packages depending on FCL are compiled as well
But then I get the classical Lazarus errors:
Recompiling sqldb, checksum changed for BufDataset
registersqldb.pas(50,38) Fatal: Can not find sqldb used by 
registersqldb, ppu=..\..\fpc\2.6.2\units\i386-win32\fcl-db\sqldb.ppu, 
package SQLDBLaz
Of course there must be more than opne copy of bufdataset.o(& ppu). 
Which one to keep and which to delete ?
I probably miss something but I can't point out what. Maybe some file 
moves to do by hand ?

Thanks for your ideaas.

Antonio.
