Problem linking (used to work)
lazarus / 32-Linux

I think my linux system must have changed without me knowing because
when I try to link a simple Project1 application I get linking errors
as follows:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
/usr/bin/ld: cannot find -lgdk-x11-2.0/usr/bin/ld: cannot find
-lgdk_pixbuf-2.0/usr/bin/ld: cannot find -lgtk-x11-2.0/usr/bin/ld:
cannot find -lgobject-2.0/usr/bin/ld: cannot find
-lglib-2.0/usr/bin/ld: cannot find -lgthread-2.0/usr/bin/ld: cannot
find -lgmodule-2.0/usr/bin/ld: cannot find -lpango-1.0/usr/bin/ld:
cannot find -lcairo/usr/bin/ld: cannot find -latk-1.0 
I don't use this particular machine very often (probably 3 months ago
since last usage).

Can anyone tell by the messages what might have happened since then?

Is the solution to uninstall Lazarus and do a re-install?

I'm using FPC 3.1, I just noticed too that the menu has disappeared
from  my lazarus IDE, is there a way to get it to come back, I tried
max/restore window, right clicking/alt-key etc. It is the new docked
layout that I am less familiar with.

Thanks

Maybe target set wrong? Compiling for 32-bit while otherwise you are
compiling for 64-bit ?

Thanks, I tried changing target options from

OS:default
CPU:default
Processor:default

To
OS:Linux
CPU:i386 (my machine is 32 bit pentium 4)
Processor: Pentium IV

I even tried switching widget set to gtk3 just in case, still no luck
though..

No, uninstall/reinstalling won't help. You even unable to reinstall.
That issue is dependency issue, all you need to do is install all the
missing libraries it told you.

I checked Lazarus 1.8 gtk (using Synaptic Package Manager), it
requires:
- libatk1.0-0
- libc6
- libcairo2
- libgdk-pixbuf2.0-0
- libglib2.0-0
- libgtk2.0-0
- libpango-1.0-0
- libpangocairo-1.0-0
- libx11-6

Missing library is a common issue on Linux. The solution is easy:
install all the missing libraries.
