I just downloaded the svn containing virtualDBGrid (from
http://code.google.com/p/luipack/source) and attempted to install the
package, but am having problems getting it to compile.

The 2nd line produces the below error messages:Code: [Select]type
  TIntegerList = specialize TFPGList <Integer>;     
QuoteC:\Laz\32432\lazarus\components\virtualdbgrid\VirtualDBGrid.pas(7
40,29) Error: Identifier not found "specialize"
C:\Laz\32432\lazarus\components\virtualdbgrid\VirtualDBGrid.pas(740,29
) Error: Error in type definition
C:\Laz\32432\lazarus\components\virtualdbgrid\VirtualDBGrid.pas(740,29
) Fatal: Syntax error, ";" expected but "identifier TFPGLIST" found
I do have the required packages (lclextensions, virtualtreeview, lcl)
loaded and working.

Any suggestions?

0.9.31-32432-2.5.1,win32-Vista

Seems your compiler version does not like generics.

Using fpc 244 without problems

Odd.  the version of 2.5.1 [2011/12/30] included with today's Laz
snapshot does not like that line.
There are already several reports of generic issues with fpc, but I'll
add one more bug report.
Thanks.

edit: an "fpc" bug report, not a laz bug report.

Try using fpc 260rc or fpc 244, the official releases

Update the svn and try again

Luiz,
Thank you.  It now compiles.

Should I see a component icon for it in the component tab someplace?

The virtualdbgrid_package.pas does not include a RegisterUnit line,
but it's CompilerOptions does say "RunAndDesignTime".

re: virtualdbgrid icon - the icon is finally showing up.

I did the following:
- removed the old version of Laz
- added a RegisterUnit line to the virtualdbgrid_package.pas file
- exported virtualdbgrid folder from the svn folder to my working
laz/component folder.

The next issue I had was three errors (see below) when I loaded
"megademo", which I resolved by removing those properties from the
Umegademo.lfm file.

Eror reading NTB.ShowTabs: Unknown property: "ShowTabs"
Error reading Page1.Caption: Unknown property: "Caption"
Error reading Page2.Caption: Unknown property: "Caption"

Luiz, thanks for the demo program.
