I downloaded some *.deb packages from here:
http://sourceforge.net/projects/lazarus/files/Lazarus%20Linux%20i386%20DEB/Lazarus%200.9.30/ and wanted to install with
dpkg -i *.deb

There was an error libc6-dev not found. (crosscompile package). Where can I get this deb package?

The installation is on a brandnew Debian 6.0.2 distribution.

Is it also possible to update an existing installation with these *.deb files above?

dpkg should have marked that dependency as broken, so you should be able to use:

apt-get -f install

to install the necessary packages from the repo. then try dpkg -i ... again.

Henry

When try to install the packages I have some kind of feeling that I will force to learn again and again to eat with knife and fork although I know already how to eat with knife and fork.

Also it feels like to be thrown back in stone age.

The win32 crosscompile package requires a lot of other packages that are not available in the debian (standard!) distribution.

I want to install fpc, lazarus and crosscompile with the deb packages (without internet access on this computer) but that seems to be impossible. I remember that is was possible easier last year.

It only requires the fpc packages (obviously), binutils and libc6dev:

It's still possible. Just install the fpc packages, binutils and libc6-dev.

Henry

fpc_crosswin... ...requires fp-units-gtk

...fp-units-gtk... ...requires libgtk2.0-dev

...and that lib requires other libs...

and so on

Why is it only possible with this libs?
Isn't it possible with the libs which has debian 'on board' ?

What does "on board" mean? Debian has libgtk2.0-dev.

Henry

That means if an installation of fpc could also be possible with less dependencies. We already discuss that here.
I installed KDE Desktop. May be then the lib libgtk2.0-dev was not installed by the debian installer.

-dev packages are almost never installed by default, because they are only required when compiling programs that link against these libraries. Most people don't compile software.

Jonas

Isn't it possible to install the stuff without these dependencies and then put later an error if these libs/units are used?
I don't think that these libs are required for crosscompiling for win32. And not all users want to compile gtk applications. Rainer

Jonas_______________________________________________ fpc-pascal maillist - http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Yes, that is possible, but that is not Debian's policy (their policy is: if it installs, it should be fully functional). If you disagree with Debian's policy, either discuss it with them, or use a different Linux distribution.

Jonas

I am always surprised how suggestions in the direction of easy install and userfriendlyness are choked because of that and that reason.

Jonas_______________________________________________ fpc-pascal maillist - http://lists.freepascal.org/mailman/listinfo/fpc-pascal

User-friendliness and ease of installation is in the eye of the beholder. This is Debian's version thereof. Every choice has its upsides and downsides.

are choked because of that and that reason.

The reason is that someone has to do the work. The current .deb files are created by the official Debian maintainers of the FPC package. If you or someone wants to create alternate .deb files without any dependencies, we can probably offer space to host them as well.

Jonas

I am not familiar with the deb system and so on, but I can imagine that this should not be _that_ hard work to do so.
For me this seems like deleting one ore more entrys somewhere in the deb file. Then more people are lucky than with the dependency rallye. Rainer

Read the man page for dpkg and search for "depends". You should be able to set dependency errors to warnings.
