It would be a nice.

I have tried. And it even work quite well now. All patches are available
in the lazarus trunk. What is missing is debugging support. There is
also a problem when resising components in the designer, probably
because Qt is still young under Haiku. I plan to write a wiki page to
explain how to build Qt, Qtpas and Lazarus on Haiku.
The official 2.4.0 for haiku is not enough to compile Lazarus. I
discover a few bugs. They are hopefully fixed in trunk and in the
One thing to do to compile lazarus under Haiku is setting gcc4 as the
current one using setgcc gcc4. Qt does not compile with the default old
gcc 2.95. Lazarus need to set gcc4 so ld look at the right libraries
Good luck with FPC and Lazarus under Haiku.
