Try compiling printer4lazarus.lpk and set the widget set to Qt.

You can also do it at the command line. For example:

~/lazarus/lazbuild -B --ws=qt ~/lazarus/components/printers/printer4lazarus.lpk

If you haven't compiled printers for your widgetset, you often get errors when you try to compile an app that depends on printers. This trips me up a lot when I test other widgetsets on Mac.

Thanks.

Right. It's like compiling the LCL against a widgetset before you can use it.

Not sure why the printers stuff isn't just part of the LCL.

When you compile printers, you'll get additional .o/.ppu files in components/printers/lib/i386-xxx/qt.

Thanks.

I haven't used Qt in a long time. Looking at the Qt interface Web page, it looks like there's some issues with the latest Qt libraries (4.7).

What version of Qt itself are you using?

What version of the Qt interface?

Thanks.

Hi all

I have the same problem with my Mint KDE/64 installation!

Lazarus 0.9.28.2-10ubuntu1 beta, FPC 2.4.0 (SVN 22277)

btw, can I update Lazarus to .9.30 without waiting for it to show up in the repository?

tnx.

Isn't it because of the QtCurve?
