Hi!

I just added MouseAndKeyInput to a project.

Everthing compiled fine, but the linker complains:

Code: Text  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i linker:
/usr/bin/ld: cannot find -lXtst
Hm, Xtst is installed. But from experience I know that it often helps
to install the devel package. So I installed the libXtst-devel.

I did not even close Lazarus. Compiled, linked, zak - everything ok.

Who is responsible for that: Suse or fpc/Lazarus?

Suse Tumbleweed 5.3.1.1, gtk 2

In practice: You.

Forcedly installing all dependencies for all libraries for which
FPC/Lazarus might have headers is not workable. Breaking up in many
packages is an half solution (e.g. debian derived distros try), and
also has its problems.

Agreed with Marco: if the developer is using something that's not
implicit to the IDE/LCL then it's his responsibility to make sure that
the prerequisites are installed, and if the distro makes that
difficult it was his choice to use that distro.

The exception is that for quite a long time it was very useful for the
end user's system to have the SQL development packages installed, but
the LCL fixed that by giving the programmer better control over which
libraries were used (i.e. rather than relying on a symlink set up by
the development packages).

Hi!

Thanx for the infos.

I just remembered that Lazarus 1.6 / Suse 13.x worked without
complaining. So Suse must have changed the packages.

I am warned for the future.
