Are Lazarus programs compatible with previous OS versions?

Are Lazarus programs compatible with previous OS versions?

I want to develop on Ubuntu 9.04 and 10.04.

Will the programs be compatible with 8.04 or even 7.04?

The programs will be non GUI for the most part.

Lazarus programs (or more precisely, LCL programs) depends on the gui toolkit and kernel version. FPC 2.4.0 requires kernel version 2.4 at the minimum.

That should be fine.

Non-GUI programs are fine there, too.

I don't remember what GTK2 versions those distro versions have. The GUI libraries are evolving and I would recommend a more recent version for GUI development. Linux can be updated for free after all.

@Lelebumbo: Linux kernel 2.4 is rather old. I guess those Ubuntus have it.

Mostly Lazarus trunk and FPC 3.2 on Manjaro Linux 64-bit.
