While we strive to maintain binary compatibility there are some
instance where we've broken source compatibility making it so that you
have to make changes to get an app that compiled under BeOS to compile
under Haiku. I've ported a few apps and there are almost always a few
changes that need to be made. My advice is to load up the app in
Paladin and see what errors there are, if the project came with a
BeIDE .proj file it is easier, if not, start a new Paladin project and
add all the files. You may need to add some libraries (Project ->
Change System Libraries) to get it compile. Look at the error messages
Paladin gives you and try to figure out what it is missing, you might
just need a different #include for it to find something.

Not all BeOS drivers are expected to work, for those that do, they
probably would only work when compiled with gcc2.

Don't attach a zip file as that will go to everyone but you can
include an error message or link to zip files hosted somewhere or
error messages on something like pastebin.com. The right mailing list
for this is haiku-3rd-party or you can ask on haiku-ports (although
that is more meant for ports from non-BeOS platforms). haiku-devel is
meant to discuss development of the OS itself.
