lglib problem
lazarus / 1-Linux

Hi all.

I've just installed Lazarus 0.9.6 for Linux but when trying to compile
I'm getting the message:

/usr/bin/ld: cannot find -lglib
project1.lpr(14,1) Error: Error while linking

It happens to any program I try to run. This one for example is only a
form and a button.
I'm running Mandrake 10.1 with kernel 2.6.8. Tried to get lglib but
couldn't find anywhere.

Any suggestions?

Thanks in advance.

Perhaps try to run ldconfig as the root user. If you've just installed
Lazarus and the FPC without a reboot then the linker may need
updating.

Two things:

1. Have you got the necessary development packages installed, i.e.
glib-devel or glib-dev, or whatever your distro calls it?

2. You probably need to edit /etc/fpc.cfg. Find the section labelled
"# searchpath for libraries" and add (or uncomment) the path to your
Gnome libraries. For example, on my SuSE system I added the line

-Fl/opt/gnome/lib

rebooting didn't work
ldconfig didn't work
editing /etc/fpc.cfg didn't work

I have both glib-devel and glibc-devel installed and none of them
provide a library called lglib. Actually, in my entire filesystem
there's no file named or partially named lglib

thanks again

I'm compiling now.
The problem was links.
When Lazarus says that couldn't find lglib it was looking for
libglib.so. The same happened to lX11 (or libX11.so) and others. So, I
linked:

ln -s /usr/lib/libglib-2.0.so /usr/lib/libglib.so
ln -s /usr/X11R6/lib/libX11.so.6 /usr/lib/libX11.so
ln -s /usr/X11R6/lib/libXi.so.6 /usr/lib/libXi.so
ln -s /usr/X11R6/lib/libXext.so.6 /usr/lib/libXext.so

It's not fully solved yet because the program doesn't run. The error:

(project1:9918): GLib-CRITICAL **: g_log_remove_handler: assertion
`handler_id > 0' failed
[FORMS.PP] ExceptionOccurred
  Sender=EAccessViolation
  Exception=Access violation
  Stack trace:

it looks like you've created a link to glib2, but unless you are
compiling lazarus for gtk2 you should have created a link to glib1
instead.

2 remarks:
* the links you have created are normally made by a -devel package

* the message lglib not found is somewhat confusing. The meaning is
that the linker couldn't find the option -l glib, so it means that it
couldn't find libglib.so
