Developing C++ app on Linux

Hi, I need to develop a C++ application for Linux, and I am worried about its compatibility with between different distros, for example if I develop it on Kubuntu, is it possible that I may have compatibility issues if I run it on Gentoo or Open SUSE for example?
In other words, what should I keep in mind to make my application compatible with other Linux distros?
Thanks,
Komyg

In case you are using some extra stuff like the Posix thread libraries or cURL or one of the many Boost libraries for C++, then you application will be restricted to run only to those platforms where those libraries have been ported to.

The same answer applies to that and is specific to the driver you are talking about.
If the driver only has one version, for Linux, then you probably wont run into any problems, if there exist different versions for different distros then you might run into problems, but in this case I guess you can only be sure by testing, maybe there aren't any differences that apply to you.

Do you think that the differences between the Kernel present in different distros could cause me problems while using those drivers?

so it's a file in the linux. what I just doing is use the scanimage utility
in the liunx. So you can read from the scanner using that scanimage
utility.Here is the man page
http://linux.die.net/man/1/scanimage
just Create another child of scanimage. It will make you're things
easy.You can even do this using shell script.
so for the GUI development you can use the Xlib , if you heavily
needs the independent among the distros. Xlib is everywhere on
evey distro's.But the life with Xlib is going to be hard.
Nothing like a kernel pannic !
