Problem with VideoTest Linux

[klacus]

Hi Folks.

I have a following troubles when I try to compile the VideoTest.lpr.

"
TFMainForm.pas(82,27) Hint: Parameter "Src" not used
/usr/bin/ld: warning: /home/kozma/Dokumentumok/lazarus/VideoTest/lib/i386-linux/link.res contains output sections; did you forget -T?
/usr/bin/ld: cannot find -lglib
VideoTest.lpr(19,1) Error: Error while linking
VideoTest.lpr(19,1) Fatal: There were 1 errors compiling module, stopping
"

I use Lazarus 0.9.28.2
Ubuntu 10.10.

What a frick is -lglib? Any dependency, or what?  Any package need for run?

I want to use my webcam, the system can handle it ex. skype. So I don't know what's wrong...
Please help me.

Best Regards
Laszlo

Hi, I use Kubuntu, the same version like you. I think lglib could be libglib. Try open your package manager and write libglib. You will see what will be found.

Hello.

Thanks for your reply.

Unfortunately I have it. I tried to install other modules, but no function.

The message probably refers to not finding the glib library.

ld prepends a "-l" before the filename if it is a library.

sudo apt-get install glib ?

You probably need the glib-devel package as well.

I already have it....

[davesimplewear]

use synaptic or apt-get and install libglib-dev

Hi all,

got the same error!
So I searched a bit and set the following:
TFMainForm.pas:
change glib to glib2 in the uses clause
RGBGTKRoutines.pas:
insert: {$DEFINE LCLgtk2} after the interface statement

Now everything compiles, but I get only a black image from my 2 different cams.
Seems the same problem as in my post about 5dpo, my cams have jpeg frames!

Any hints ?
