I've recently upgraded from Ubuntu 10.04 to Fedora 16 with Gnome Shell and I've been getting a strange error using TTabControl. Creating a blank form and dropping a single tab control on to it raises EInterfaceCritical: "clearlooks_style_draw_box_gap: assertion 'height >= -1' failed". My application features quite a few TTabControls in various options dialogs, and I was wondering if anyone has a workaround for this. They were all functional using Gnome 2, and now opening any form with a TTabControl raises this error in Gnome 3.

Thanks for your time,
David

I have been trying to install the lazdbexport pkg on OSX and it will not compile for nothing.

My Error is:

/Developer/lazarus/components/dbexport/fpdataexporter.pp(1,1) Fatal:
Can't find unit fpdbexport used by fpdataexporter

The odd part is if I right click on fpdbexport in the fpdataexporter unit and select find declaration it goes right that unit no problem so I don't understand how the compiler cannot find it? I check and it appears the path is in my search path?

Any ideas on how to overcome this? I want to be able to use the Lazarus Data Desktop app if possible.

Thanks,

Tom

For browsing the source, you don't need the compiled units. To compile fpdataexporter you need fpdbexport.ppu. I guess fpdbexport is not compiled on Mac OS X. I don't know why, better ask the fpc team.
