Building Qt under Haiku
Instructions are available there : http://qt-haiku.ru/index.php?option=com_content&view=article&id=53&Itemid=67
Building Qt is not required. You can just download lastest binaries at [1] and uncompress it to /boot/.
In order to compile the qt4pas binding below, you should get the development package.
Building Qt4 binding for FreePascal under Haiku
Download the source from [2]. The current binding is "V2.1 (Qt 4.5.X, compatible with Qt 4.6.X)". Choose the entry "Library source" under the Linux X11.

Building Lazarus under Haiku
Required tools
fpc 2.4.0 for Haiku is not suitable to build Lazarus. Some bugs were fixed while porting Lazarus to Haiku.
The 2.4 fix branch or trunk should compile Lazarus.
Getting sources
As usual :
svn co http://svn.freepascal.org/svn/lazarus/trunk lazarus
Compiling Lazarus
Once you have a good enough compiler and the source tree, just run at the root of the source tree
Make sure gcc 4 is the default compiler under Haiku using :
setgcc gcc4
then :
make LCL_PLATFORM=qt
