Newbie on Linux: error while linking -lX11
lazarus / 1-Linux

----------------------------------------------------------------------

I've just had a Linux (Freespire) machine. Now I need to know how to
run Lazarus on it. I've tried compiling with LCL_PLATFORM set to
either gtk1 or gtk2. On gtk1, it fails on -lglib (OK, maybe I
installed it in the wrong place). Changing it to gtk2 gives me
surprises: error while linking -lX11. The linker can't find X11! How
can it be?! Anyone know solution to this?

This is a FAQ: since you're doing development, you need to install the
devel versions of the gtk and x11 packages.

Hello,
I have this same problem:
..
Linking ../lazarus
/usr/bin/ld: cannot find -lX11
lazarus.pp(125,1) Error: Error while linking
..
I have: ubuntu 9.04, fpc 2.2.4 and lazarus 0.9.26.
If the issue is finished for you, please hint what to do?
Best regards, sp3iq.

Look at this http://www.lazarus.freepascal.org/index.php/topic,6814.ms
g31822.html#msg31822

This was a successful installation

Thanks very much, but its next problem.
My report:
1. sudo apt-get install X-dev libX11-dev libXi-dev libXmu-dev
Couldn't find package X-dev

2. sudo apt-get install xorg-dev libX11-dev libXi-dev libXmu-dev
Install OK.

3. make clean all LCL_PLATFORM=gtk2
Linker went on, but its next problem:
..
Linking ../lazarus
/usr/bin/ld: cannot find -lgdk_pixbuf-2.0
lazarus.pp(125,1) Error: Error while linking

I looking for now gdk_pixbuf-2.0 (?).
Does anyone know what to do to the linker was ok?
Best regards, sp3iq.

Try install
libgdk-pixbuf-dev
and then (gtk2)
libgtk2.0-dev

In the beginning was:
Linking ../lazarus
cannot find -lX11
So I installed libX11:
sudo apt-get install xorg-dev libX11-dev libXi-dev libXmu-dev

Currently I have a problem: the linker says something different than
the system
1. Linker:
Linking ../lazarus
/usr/bin/ld: cannot find -lgdk_pixbuf-2.0
lazarus.pp(125,1) Error: Error while linking

2. Attempting installation libgdk_pixbuf:
sudo apt-get install libgdk-pixbuf
Could not find package libgdk-pixbuf

3.  Attempting installation libgdk_pixbuf2:
sudo apt-get install libgdk-pixbuf2
Reading package lists ... Done Building dependency tree Reading state
information ... Ready libgdk-pixbuf2 is already the newest version

Which name of a missing library: gdk_pixbuf-2.0 is responsible ?
Best regards, sp3iq.

Like you did for X11, you need libgdk_pixbuf2-dev

Hi,
I installed libgtk2.0-dev:
sudo apt-get install libgtk2.0-dev
and problems with the linker process is ended.
Now I have version 0.9.27 Lazarus
(svn update .. I got #20843)
Thank you all for your help.
Best regards, sp3iq.
