/usr/bin/ld: warning: link.res contains output sections; did you forget -T?

[iru]

Gentlefolk,

I installed Lazarus on Ubuntu 11.04 following instructions from 'silvio' as follows:

wget -c http://silvioprog.com.br/download/install_fpc_lazarus_svn_version.tar.gz

 tar -vzxf install_fpc_lazarus_svn_version.tar.gz

 ./install_fpc_lazarus_svn_version.sh

Worked beautifully, Lazarus IDE version 0.9.31, svn 31208.

But when I try to compile a simple form with one button I get an error message:

/usr/bin/ld: warning: link.res contains output sections; did you forget -T?

A general Google check and a check of the forum for something like this showed nothing.

Any ideas??

Thanks, Ian

It is just a warning,  not an error.  Everything should work.

There are dozens of such warnings while compiling FPC or Lazarus themselves.

Gentlefolk,

Thanks for the response.

However the messages window was a little small and I now see a long list of errors as follows:

/usr/bin/ld: warning: link.res contains output sections; did you forget -T?
/usr/bin/ld: cannot find -lX11
/usr/bin/ld: cannot find -lgdk_pixbuf-2.0
/usr/bin/ld: cannot find -lgtk-x11-2.0
/usr/bin/ld: cannot find -lgdk-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 -latk-1.0
/usr/bin/ld: cannot find -lcairo
project1.lpr(20,1) Error: Error while linking
project1.lpr(20,1) Fatal: There were 1 errors compiling module, stopping

It looks like the install process did not set up links to the required files/libraries or these are missing.

Any suggestions?

Thanks, Ian

Gentlefolk,

A little more chasing shows an entry in the forum reporting the same problem.

The contents of the response are a little beyond me but there is the comment:

"This is only developers headers for FPC compiler. Compiled executable run on ubuntu without this packages".

I believe this is telling me that some portion/s of the FPC compiler are missing.

It is not.  Probably you didn't install the development packages for those packages (GTK2 and its dependancies) are not installed.

Iru, you did not install the prerequisite Linux packages for FPC/Lazarus.

Before you start with FPC/Lazarus compilations, you need to have at least the following packages installed:
build-essential libx11-dev libgtk2.0-dev libgdk-pixbuf-dev

(there might be more)
you can do this in a terminal window with a

Code: [Select]

sudo apt-get install build-essential libx11-dev libgtk2.0-dev libgdk-pixbuf-dev

Gentlefolk,

Thank you for the responses, I am getting there!

However I (and the APT-GET and the Synaptic Package manager) cannot find libgdk-pixbuf-dev anywhere.

is this the correct name/spelling/?

Thanks, Ian

[bobo]

If you still get errors regarding pixbuf, you need to find it. Did you try with just the others installed?

I am not sure what is it called exactly in Ubuntu 11.04 , maybe libgdk-pixbuf2.0-dev or something similar. Look for packages with pixbuf in their name.

try to search on usr/lib .
i believe the needed library is somewhere in your system but with different name.
 i also get same problem couple years ago..

then if you have found it, do something like this

Code: [Select]

sudo ln -s /usr/lib/libgtk-x11-2.0.so.0.2000.1 /usr/lib/libgtk-x11-2.0.so

Gentlefolk,

Thanks for the responses and the suggestions contained.

I surfed around /usr/lib found something like lgkd_pixbuf-2.0, checked it out in the update manager.

All seemed OK.

Read: http://lazarus.freepascal.org/index.php/topic,6125.0.html.

Chased around some more. Rebooted Linu, restarted Lazarus, compiled a basic program OK.

Not sure exactly what solved the problem.....

Thanks Ian
